With its energetic dynamics, wide soundstage and pleasant sound quality, it was enthusiastically received by hi-fi users worldwide. It gradually became known among audiophiles as a great example of ‘balanced headphones’ and far exceeded expectations in terms of popularity. It is still a competitive headphone on the market today. The new FIIO FH19 from FIIO is a significant upgrade that incorporates a lot of user feedback. It retains the distinctive sound and premium build quality of the FH9 and has also been developed in partnership with Tokyo Onkyo Ltd. in Japan and Knowles in the USA. It features a truly high-end acoustic design, with richer and fuller mids and a more robust yet flexible bass. In addition, the fit has been redesigned and optimised based on the characteristics of the human ear, so you can enjoy flagship-level comfort. The top, further improved The new FIIO FH19 is equipped with two 13.7mm dynamic drivers and six balanced armature drivers, matching the flagship. The bass is reproduced by a completely new push-pull dual dynamic driver unit, which was developed jointly with Tokyo Onkyo Ltd. in Japan. This driver is characterised by significantly improved extension, cohesion and speed in the low frequency range. The mid to high frequencies are handled by specially adapted, improved Knowles Balanced Armature drivers for the midrange, achieving greater sound energy density for rich and delicate vocals that are wonderfully musical without sacrificing detail. As the cones move back and forth, the overall direction of movement of the two dynamic drivers remains consistent due to the push-pull arrangement, ensuring phase consistency. This effectively doubles the driving force and allows the diaphragms to damp each other with air. As a result, the dynamic drivers exhibit more stable movement and completely suppress any residual sound after the end of the audio signal. Compared to typical dynamic drivers, push-pull dual dynamic drivers require only half the amplitude to reach the target sound pressure level. This results in lower cone excursion, which significantly improves linear drive performance and further reduces intermodulation distortion, allowing the driver unit to deliver a cleaner sound. Customised Knowles Enhanced Mid-BA Drivers The FIIO FH19 uses six Knowles Balanced-Armature drivers as mid and high frequency units. To achieve an even higher level of vocal sound quality, FIIO has worked with Knowles to develop a custom balanced armature driver with enhanced midrange. By adding acoustic vents in the rear cavity of the driver, the mid-frequency driver gains more sound energy compared to typical mid-frequency drivers. This brings out the benefits of the midrange driver even more, resulting in rich and smooth vocals that sound as immersive and realistic as if the singer were standing right next to you. 7000 Series titanium and aluminium construction The FIIO FH19 boasts a build quality worthy of a flagship speaker, helped by its titanium centre frame. Its luxurious feel and uniquely charming titanium colour give it a premium look. As the part of the headphones that is touched the most, the rigidity and corrosion resistance of the pure titanium metal bracket thoroughly protects the rest of the headphone housing and makes it resistant to everyday wear and tear. The FIIO FH19 uses 7000 series aluminium*, which ensures a robust and resistant housing while reducing the weight of the headphones. Thanks to this aluminium, the FH19 offers a comfortable wearing experience even with more drivers and a more complex acoustic design. *7000 series aluminium alloy is widely used for aircraft fuselages, wings and other important components. It has high strength, rigidity and corrosion resistance. Fatigue-free listening, large sound stage Semi-open design The semi-open design was highly praised in the FIIO FH9, FH7S, FH5S and FD5. In the FH19, this proven semi-open design is used again and has been specially adapted to combine with FIIO's balanced pressure relief technology for the front and rear cavities - the result is a more natural and relaxed sound with a wide sound stage. This design efficiently equalises internal air pressure, eliminating the feeling of pressure on the eardrum, which also helps protect your hearing. Enjoy long listening without fatigue. Mid-frequency cut-off filter The FH19 features a variety of different drivers and acoustic design principles. The scientific tuning of the individual parts so that they form a harmonious whole is the essence of high-level tuning. To achieve this, the FIIO development team has developed a special ‘mid-frequency cut filter’ for the FH19 hybrid earphones. Further enhanced mid-range tests have shown that the FH19's mid-frequency cut filter not only retains the high resolution and clarity of the BA drivers, but also increases the sound pressure level in the mid-frequency range. This makes the vocals denser and fuller while ensuring a smooth transition between the dynamic driver and the BA driver for the mid frequencies. The FH19's mid-frequency cut-off filter effectively filters out the high-frequency 8 kHz peaks generated by the mid-range drivers. This reduces the overlap between the sound produced by the midrange and tweeter drivers, eliminating sibilance while ensuring high sound quality. The mid-frequency cut-off filter can also advance the crossover point of the balanced armature units. This ensures that these drivers have a truly independent frequency range and there is no interference with the other drivers, allowing the tweeters to perform to their full potential. The working principle of the FH19's mid-frequency cut-off filter: When the frequency of the sound wave is close to the natural frequency of the resonance chamber, the inner wall of the resonance chamber and the air generate vibrational friction, which converts the sound energy of certain frequency bands into mechanical and thermal energy, thereby consuming sound energy and achieving a sound absorption effect. Conversely, the resonance effect in the cavity is weaker if the frequency of the sound wave is far away from the natural frequency of the resonance chamber, resulting in less sound absorption. This principle forms the basis for the operation of the FH19's mid-frequency cut-off filter, which adjusts the sound produced by the mid-range drivers and achieves a physical pass-through effect. Focusing on small details to achieve big improvements Suspended voice coil To achieve flagship-level driver performance, the FIIO FH19 utilises a suspended voice coil. With this design, the voice coil leads are routed directly from the centre hole underneath the cone, allowing them to float in the gap. This avoids unnecessary contact and prevents additional adhesive load. Compared to conventional diaphragms*, the floating voice coil design ensures smooth and gentle diaphragm movement, minimising interference from other factors and fully exploiting the diaphragm's inherent potential. *Conventional diaphragms often use special adhesives to bond the voice coil to the diaphragm surface. However, this approach not only increases the overall weight of the diaphragm, but can also lead to a dynamic imbalance during dynamic movements of the driver. Uneven local weight distribution can lead to vibration irregularities, change the compliance of the cone and even cause distortion due to voice coil scraping. This ultimately affects the overall performance of the driver. Scalpel-like accuracy Rubycon audiophile-grade film capacitor crossovers The FH19 is equipped with the same high-precision Japanese film capacitors as the FA19, which offer exceptional accuracy in phase matching and have been developed with the utmost care for sound quality. While conventional resistor-based crossover components typically have an accuracy error of around 1%, the FH19 achieves an impressively low error rate of 0.1%. In addition, the FH19 not only achieves more precise crossover points compared to conventional ceramic capacitors, but also effectively improves the resolution in the high frequency range and results in a more detailed sound overall. Acoustic four-way design "While the basic design is derived from the FH9, the FH19 builds on and surpasses its predecessor by updating the bass and midrange drivers and implementing them in a more precisely controlled four-way crossover design. Special push-pull dual dynamic driver units are used in the low frequency range, and a ‘Turbine Low-Frequency Boost Technology’ is used for physical low-pass filtering for relaxed yet natural bass. For the mid frequencies, the FH19 introduces an innovative ‘3+1 semi-open’ acoustic layout with balanced armatures. This is complemented by a newly designed resonance chamber that allows for two separately managed mid-range areas, resulting in richer and more emotional mids. For the high frequencies, the FH19 retains the coaxial design with an acoustic guide, but also incorporates audiophile-quality Rubycon film capacitors. This combination enables high resolution with excellent high frequency response." Chief Engineer of FIIO IEM's R&D Centre Turbo-charged energy Patented S.Turbo design Inspired by turbochargers in super sports cars, the FIIO development team has created the patented S.Turbo acoustic design. This design ingeniously utilises the properties of sound wave guidance and improves bass performance through a turbine-shaped structure. The result is a deep and lively bass. In addition, the design skilfully filters out excess mid to high frequencies from the dynamic driver, ensuring smooth transitions between the low and mid to high frequencies. The result is a powerful and robust sound. Patent number: ZL2018211416279 Interchangeable audio filters As befits an IEM flagship, the FH19 has three pairs of interchangeable audio filters. Each filter has a different internal attenuation and mesh density, so you can customise the sound to your preference: Red audio filter - Boosts low frequencies and provides powerful and impressive bass Black audio filter - Provides a balanced sound that is clear and transparent Green audio filter - Delivers fine and detailed highs *Green filter is pre-installed. The other filters are included in the carrying case. Top-class comfort Optimised wearing ergonomics 10° ear cup angle Based on user feedback and numerous optimisations, the angle between the ear cup and the wearing surface along the Y-axis is exactly 10°, while the length of the ear cup remains unchanged. This adjustment means that the earphones fit even more precisely in the ear canal, which significantly improves both wearing comfort and stability. Gap-free, comfortable fit, the FH19 has a completely new, more three-dimensional rear recess design. Numerous tests led to numerous ergonomic optimisations, such as ear-friendly protrusions with a thickness of approx. 1.4 mm, which ensure a firm and stable fit by minimising any unwanted movement. The brand new design of the FH19 back panel features a slight reduction in thickness - approximately 1 mm - in the area corresponding to the fold of the human ear. This structural design significantly reduces the feeling of pressure and compression on the ear from the earphones. In combination with the excellent housing materials, the FH19 disappears into your ears while delivering a first-class sound. Pure silver for pure sound The FH19 comes with a high-purity pure silver cable as standard. Each of the 8 strands consists of 28 wires, totalling 224 wires. Each individual wire is insulated with enamel and the cable is braided into strands. The outer jacket is made of imported, transparent and environmentally friendly TPU, which enhances the transparent appearance of the cable. In addition, this material effectively prevents the cable from yellowing with prolonged use and becoming stiff at low temperatures. *The cable is identical to the LC-RD Pro 2022 Straight, interchangeable twist-lock audio plugs Supports 3.5/4.4 mm plugs and features extended stainless steel MMCX plugs *Patent for interchangeable audio plugs licensed by FABRILOUS. Listen the way you want 22 pairs of ear tips included As befits a flagship model, the FH19 comes with 22 pairs of ear tips in different shapes and sizes* to give you a comfortable listening experience no matter what your preferences are. In addition to the popular HS18 and SpinFit ear tips, the new HS18 silicone ear tips are also included. Specifications Headphone type: Hybrid in-ear monitors with dynamic and BA fittings Frequency response: 8Hz-40kHz Impedance: 16Ω@1kHz Sensitivity: 109dB/mW@1kHz Cable type: 8 strands with a total of 224 wires of high-purity pure silver Length of cable: Approximately 1.2m Weight of headphone unit: Approximately 12g (without cable) Earphone connection: Extended MMCX Audio plug: Straight twist-lock plug3 pairs of HS20 silicone ear tips (S/M/L) 3 pairs of HS18 ear tips (S/M/L) 3 pairs of SpinFit ear tips (S/M/L) 2 pairs of foam ear tips (M) 3 pairs of bass ear tips (S/M/L) 3 pairs of balanced ear tips (S/M/L) (size M pre-installed) 3 pairs of vocal ear tips (S/M/L) 2 pairs of dual flange ear tips (M) 1x HB7 carrying case 1x cleaning brush 1x MMCX quick release 1x magnetic cable clip 1 set of audio filters red/black/green 1x pure silver earphone cable with interchangeable plug 3. 5/4.4 mm 1x quick start guide

It was developed from the ground up by experienced acoustic engineers at FiiO. It features an ultra-thin 1-µm diaphragm with a double-coated, patented design. With professional tuning adjustments from FiiO, the FP3 achieves a wide stage, deep bass response and detailed, extended treble reproduction with a frequency response of up to 40 kHz. The driver is precision manufactured with nanometre-level accuracy. It was manufactured using a 28 nm process. Ultra-thin diaphragm and precision engineered driver The planar magnetic driver of the FiiO FP3 utilises an ultra-thin 1-µm diaphragm. It is made from high-performance PET as the substrate material for the diaphragm. It is extremely lightweight and combined with its ultra-thin design, it achieves lightning-fast movement speed, resulting in faster transients, improved dynamics and low distortion in sound output. The driver utilises FiiO's own patented double coating system. The planar driver uses a PET diaphragm substrate with an aluminium and titanium material coating to form a double-coated driver unit. The first layer is made of aluminium, while the second coating layer is made of titanium. Super Strong Magnetic Architecture The FiiO FP3 has a strong, powerful magnetic architecture. Each driver has 14 powerful N52 neodymium magnets, seven on each side of the driver. The balanced placement of these magnets allows for an evenly distributed, uniform diaphragm of the double-coated driver. The diaphragm experiences balanced forces on both sides, resulting in smooth movement that improves sound efficiency and also reduces distortion. Improved bass response with ‘Tesla Valve’ acoustic technology The FiiO FP3 features the same patented ‘Tesla Valve’ bass enhancement technology as the highly acclaimed FD15 IEMs. The length, angle and number of channels in the FP3's cavity have been optimised to achieve a fluid Tesla Valve structure.

Wired over-ear headphones Solid American black walnut shells 60 mm dynamic driver Nanowood fibre composite diaphragm W-shaped suspension seal Closed-back design U-shaped acoustic damping tube Conical baffle plate 32 Ω high sensitivity design 3.5 mm and 4.4 mm headphone cables included High-quality headphone storage bag Sound of nature The FIIO FT1 cups are made from carefully selected American black walnut in FAS quality. The smooth grain of the wood, which is unique to each piece, and the fine texture bring out its natural beauty. This very dense solid wood also helps to effectively reduce cavity resonances and minimise standing waves. 60 mm dynamic driver The FIIO FT1 features a newly developed 60 mm second-generation dynamic driver specifically designed for FIIO's first closed-back over-ear headphones. The larger-than-average driver improves the efficiency of energy conversion and provides a solid foundation for powerful bass. In addition, the larger size of the driver results in lower resonance points at low frequencies, allowing for deeper bass, dynamic sound and an overall authoritative sound. Nanofibre composite cone - paper making technology and the art of sound The cone of the FIIO FT1 is mainly made of carefully selected paper wood fibres based on 90 year old spruce wood from Northern Europe. European spruce is a premium raw material for musical instruments and fibre products, known for its clear and natural sound. Mature northern European spruce wood undergoes a series of processes including soaking, boiling and beating to produce a specific pulp. A certain amount of carbon fibre material is added to meet the acoustic resilience requirements. The membrane is then baked and moulded in a further round so that it finally reaches a thickness of around 0.1 mm, is light and resistant. To bring out the full acoustic performance of the nano wood fibres, a lightweight PU material with high internal resistance is used for the suspension seal, which improves the compliance of the diaphragm and increases elasticity in the low frequency range, enhancing the density of voices from the sound source, resulting in warm, rich voices. In keeping with its overall acoustic concept and high-quality listening experience, the FIIO FT1 uses a nano wood fibre cone. This membrane consists of carefully selected paper fibres in combination with a lightweight PU (polyurethane) suspension seal. It is characterised by excellent high-frequency extension and excellent transient response, resulting in a clean, precise sound with clear imaging and giving you the unique sweet, rich and dense midrange sound of paper cones. This driver works in harmony with the FT1's other acoustic design elements to deliver a specially tuned frequency response for a pure and pleasing sound experience. It's as if the elegant aesthetics of the ‘paper’ driver translate perfectly into beautiful sound. Cutting-edge technology and innovative applications The FIIO FT1, FIIO's first closed-back over-ear headphones, pioneers a new generation of in-house acoustic technology - the W-shaped suspension seal. The 25 mm diameter voice coil is larger compared to similar models and has been specially optimised and tuned. Compared to typical, similarly sized cones, the W-shaped cone achieves a 25.8 % larger effective vibrating area, allowing it to store more energy reserves. The FT1's cone with a hard dome and a compliant suspension seal allows the 25 mm voice coil to drive the stiffer dome region directly. This design minimises vibration losses between the different materials and reduces distortion caused by driver break-up, allowing the FT1 to deliver a more refined sound. Ultra-fine Japanese CCAW voice coil To ensure a robust and high-quality sound, the FIIO FT1 uses a specially imported Japanese ultra-fine CCAW (Copper-Clad Aluminium Wire) voice coil with a diameter of up to 25 mm. A longer copper wire of the voice coil can directly improve the efficiency of the transducer and the drive capacity, resulting in a better transient response and a purer, more pleasant sound. Each individual wire core in the CCAW coil has a diameter of approx. 0.035 mm and is therefore as thin as a hair. In addition, the voice coil frame of the FT1 is made of lightweight KSV (Kapton), which also contributes to a significant reduction in overall cone mass. The result is improved response speed and minimised reverberation. Closed-back design The FT1 is FIIO's first closed-back over-ear headphones and incorporates a number of features specifically designed to enhance the closed-back listening experience. A series of sound-absorbing components in the FT1 effectively reduce ambient noise, including external voices and ambient noise, by up to 26 dB. Whether you're commuting, editing recordings, working in the office or gaming, the FT1 lets you immerse yourself in a high-fidelity audio world. It is a truly great sounding all-rounder headphone. U-shaped sound attenuation tube for improved noise reduction The U-shaped sound attenuation tube specially developed for the FIIO FT1 not only improves passive noise reduction, but also ensures that sound energy is channelled through the flute over a certain length and angle, increasing the air viscosity and reducing the resonance frequency of the cavity. This further improves the bass expansion. You will clearly feel the air movement and the focussed power of percussion and strings. Conical baffle The pursuit of excellent sound has always been the essence of hi-fi. Based on the characteristics of the FT1 dynamic drivers, the development team has designed a conical baffle for them. This device allows the entire driver to be positioned parallel to the human ear, breaking sound convergence and avoiding standing waves. The result is minimal attenuation of high frequencies for true hi-fi sound quality. 32-Ω design with high sensitivity The FIIO FT1 is designed to provide users with a high-quality hi-fi experience in various usage scenarios. To achieve this, the FT1 has a low impedance of 32Ω and offers an acoustic sensitivity of 113dB/Vrms@1kHz (equivalent to 98dB/mW@1kHz). This significantly reduces the need for drive power, allowing you to enjoy outstanding sound quality effortlessly. Adaptive 3-axis headband The FT1 has inherited the excellent ergonomic design of the FIIO FT series. The adaptive 3-axis headband allows free rotation at different angles. This design adapts to different head sizes and ensures a snug fit on the head for improved comfort and minimised sound loss. 10Hz-40kHz ultra-wide frequency response The FIIO FT1 has a frequency response of 10 Hz to 40 kHz, providing a studio-like listening experience. Every little detail is reproduced cleanly, just as you would expect from a professional audio device. Lightweight, portable headband To make the FT1 headband more portable and lighter, it is equipped with high-quality steel rails that significantly increase the durability of the headband. You will feel the precision and sophistication of the mechanical construction every time you adjust the headband. In addition, compared to similar products, the FT1 offers an extended adjustment range from 0 to 11 clicks to adapt to different head sizes. The part of the headband that comes into contact with the head is made of lychee leather for a soft and comfortable feel. Breathable fabric ear pads Experience comfortable long listening sessions and say goodbye to congestion. The FT1 is equipped with breathable fabric ear pads, which are made of a textile material that comes into contact with your skin. The high-density, breathable mesh design efficiently dissipates the heat that builds up between the ear pads and your ears. The side of the ear pads is made of protein leather, which not only looks good, but feels good too. Dual TRS headphone jacks The FIIO FT1 features two 3.5mm TRS headphone jacks, allowing you to easily switch and upgrade to a different headphone cable. Includes high-quality headphone storage bag The FT1 comes with a high-quality headphone storage bag, made with the same materials and techniques used by top French brands. It offers a refined and elegant look rarely found in this class, but undoubtedly useful for protection. 2 silver-plated oxygen-free copper cables included The brand new FT1 comes with two headphone cables - with 3.5 mm plugs (single-ended) and 4.4 mm plugs (balanced). Both cables are identical and consist of an oxygen-free, copper-coated silver wire base with 392 wires, have a thickness of 24AWG and are 1.5 metres long.

FiiO FT3 - 350 Ohm Version Large Dynamic High-Res Over-Ear Headphones 60mm large dynamic driver Beryllium-plated gasket + DLC diaphragm 350Ω high impedance Asymmetric internal and external magnetic circuit system Open-back design Furukawa monocrystalline copper cable Aluminum alloy construction Lightweight hollow design 4 different audio plugs included Vast sound quality headroom, Experience pure “blackground”The FT3 350Ω version features a black background, or a “blackground” for a true high-end sound experience. The 350Ω design also gives you much room to explore its sound quality. With a powerful, high-quality amplifier you can tap into the vast sound potential of the FT3 350Ω version – experience its fully extended treble and bass, vast soundstage, and ultimately relaxing yet powerful soun Art of harnessing energy for great sound - 60mm large dynamic driverSound comes from the vibration of material – thus, the choice of the driver is quite important in determining sound quality. The FT3 features a large 60mm dynamic driver, uncommon in its class. Compared to a smaller driver, the FT3 can push more air and convert energy into the sound more efficiently – resulting in a more natural yet robust sound with an expansive soundstage.The FT3’s large dynamic driver also has other benefits. For example, due to its large size, the diaphragm is capable of bearing higher output power, leading to less distortion under large dynamic signals. Also, the larger driver is more easily able to produce lower frequencies for deeper reaching bass. Thoughtfully designed - Beryllium-plated gasket + DLC diaphragmThe diaphragm is one of the most important parts of a dynamic driver. And not just any diaphragm material can meet the demands of the FT3 due to the large driver size. After countless testing at FiiO, a beryllium-plated gasket + DLC diaphragm was chosen.The FT3 driver gasket is plated with beryllium. This not only results in a lighter gasket (and thus a lighter driver), but also a more rigid gasket better able to handle the movement of the large dynamic driver for less distortion. The diaphragm of the FT3 is made of DLC (Diamond-Like Carbon),  – which is both highly sturdy and lightweight compared to other diaphragm materials. This means that the FT3 driver is less prone to breakup and thus nonlinear distortion, while also having an extremely extended frequency response and improved soundstage. Pure sound - 350Ω high impedanceThe FT3 was designed with great sound as the primary goal, and features 350Ω impedance to achieve that. Compared to lower impedance headphones, higher impedance headphones more effectively filter out noise to the listener resulting in a purer sound with higher signal-to-noise ratio performanceThe voice coil is made of ultra-fine Japanese copper-clad aluminum only 0.035mm thick in diameter. This finer voice coil allows the driver to better and more quickly follow signals, has anti-interference capabilities, and allows for thunderous dynamics across a wide frequency response range.Hear the artist’s intent - Asymmetrical internal and external magnetic circuit systemThe FT3 utilizes powerful N52 neodymium magnets to maximize sound quality under its 350Ω impedance design. These magnets have been arranged in an optimized asymmetrical internal and external magnetic circuit system. When the voice coil starts to move during the reproduction of sound, the optimized magnetic circuit balances this movement of the voice coil and diaphragm, especially during large dynamic changes - which allows more effective use of magnetic energy and better control over the voice coil. Quality cable - Furukawa monocrystalline copper wireStandard with the FT3 is a 3m, 23AWG diameter cable consisting of high-purity Furukawa monocrystalline copper wire.Outer shell material: TPEShielding layer: PCOCC-A (26/0.12X2) Insulating layer: PFA Conductor: PCOCC-A (3/20/0.8X2AWG23)Outermost diameter: 2.4mmx2 (parallel structure)Widely compatible - 4 swappable audio plugs come standardThe FT3 cable features swappable plugs of the following 4 kinds:3.5mm/4.4mm swappable plugs3.5mm to 6.35mm adapter4.4mm to XLR-4 balanced adapter*Interchangeable audio plugs are officially licensed from the patent by FABRILOUS.Lighter and stronger - Aluminum alloy constructionThe exterior of the FT3 is made entirely of aluminum alloy that not only feels luxurious to the touch, but is also highly rigid yet lightweight. This gives the FT3 the perfect combination of being comfortable to listen to and being durable enough to withstand life’s challenges.Full of comfort - With a lightweight hollow mesh designThe FT3’s design begins with hexagonal elements as its base, and when combined with how open-backed headphones usually look, gives off a bold sci-fi appearance. The open-back design features a hollowed-out mesh to not only further reduce the weight for greater listening comfort, but also to fully unleash the capabilities of its driver in a more open environment. Removing a layer of veil from your music - Open-backed designThe FT3 features an open-backed design that reduces unwanted vibrations and resonances and results in a larger soundstage, since when the driver is pushing air in the housing the open-back means that air encounters. The result is that details in the music come through more clearly and naturally in a wide open soundstage, just as if you were listening to a live performance.Free to rotate - 3-axis swiveling designThe FT3 has undergone much fit testing in FiiO Labs, and the 3-axis swiveling design is one result of that testing. The 3-axis swiveling design was specifically made so that the FT3 could better fit a wide variety of head and face shapes for improved comfort and better seal to maximize sound quality.Innovative touches - Angled drivers parallel to the earThe FT3’s driver is placed at an angle to be parallel to the ear when worn, which helps to reduce high-frequency response caused by the waves hitting the contour of the ear and not entering it. Angled drivers can also minimize unwanted reflections caused by the shell of the headphone that would cause standing waves and also reduce frequency response distortion. Additionally, towards the rear of the FT3’s shell is a reflective tip that is specifically designed to direct soundwaves produced by the driver to prevent unwanted reflections from interfering with each other, to both further minimize sound flaws and reduce unwanted frequency response artifacts. Rich sounds - 2 sets of distinct-sounding earpadsThe FT3 comes with 2 sets of earpads, each with their own soundSuede earpads: Balanced sound, enhanced ambience, majestic experienceImmitation leather earpads: Clear sound, large soundstage, highly detailedThorough protection - Storage bag includedThe FT3 comes with a storage bag, which comprehensively protects your headphones in a light yet luxurious feeling package.FT3 Basic specificationsHeadphone type: Dynamic driver headphonesFrequency response: 7Hz-40kHzDriver type: 60mm dynamic driverDiaphragm material: Beryllium-plated gasket + DLC diaphragmImpedance: 350ΩSensitivity: 102dB (1Vrms)@1kHzWeight: About 391g (excluding cable)Earpad pressure: 4.0N±0.3NCable length: About 3mCable material: Furukawa monocrystalline copper wireHeadphone connector: Dual 3.5mmAbundant accessories3.5mm interchangeable plug    4.4mm interchangeable plug    3.5mm female to 6.35mm male adapter    4.4mm female to XLR-4 male balanced adapter    Storage case    Imitiation leather earpads    Suede earpads

This time, I've transferred that experience to headphones with a newly developed and designed full-size 106mm planar driver. Several innovative acoustic patent technologies are used to further enhance the ultra-low frequency response capabilities of planar headphones.” -Joseph Chief Engineer of the FiiO IEM R&D Center Gold and silver bring out the best in each other Patented multi-layer gold and silver coating of the coils The FT7 uses FiiO's proprietary planar driver technology*—a patented multi-layer coating system. The planar driver uses high-performance PET as the diaphragm substrate and selectively applies gold and silver to create a multi-layer coated driver, thus utilizing the advantages of these two precious metals. This allows the FT7 to deliver an extremely detailed yet charming sound. Gold: Gold has a high density, very high internal resistance, and excellent ductility. The additional gold coating improves the damping of the membrane, making the mid and low frequencies sound relaxed and pleasant. Silver: Silver is characterized by low resistance and high electrical conductivity. High-frequency currents flow quickly and with minimal loss through pure silver material, resulting in very detailed highs. In addition, silver is not very dense and is lightweight, which improves the sensitivity of the driver. *Patent number: ZL2024205488218 Top-of-the-line planar driver 1μm thin diaphragm Engineers have constantly strived to develop thinner and lighter diaphragms for planar drivers. After two years of independent research and development, FiiO has developed a class-leading, ultra-thin 1μm diaphragm for the FT7, which uses high-performance PET as the carrier material. The difference between a 2μm and a 1μm diaphragm thickness results in noticeable performance differences when the diaphragm vibrates at high speeds, which ultimately affects the sound quality. The FT7's ultra-thin 1 μm diaphragm is exceptionally light and can respond at lightning speed. It reproduces even subtle sounds in the ultra-high frequency range faithfully and offers an exceptional dynamic range. *The driver is printed with the words “Designed and manufactured by FIIO”. Advanced technology for advanced sound 28 nm process technology To ensure that the driver diaphragm can be manufactured to a sufficiently high standard, the FiiO FT7 driver is manufactured using a 28 nm process. Inspired by the coating technology used in the semiconductor industry, this technique completely isolates the conductive circuit material from the ambient air. The conductor material is placed in a vacuum with a pressure of 6.6 × 10-³ pascals, and the temperature is raised to 120 °C. The conductor material is converted into ionized particles, which then accumulate on an ultra-thin 1 μm film through the principle of charge attraction. This process achieves the desired layer thickness for optimal acoustics and significantly increases the durability and service life of the conductor tracks*. *Contrary to popular belief that planar drivers have a short service life, the proprietary driver was subjected to aging tests in FiiO laboratories for over a year. During this test period, there were no cases of delamination, separation, or wire breakage in general. The sound quality continues to meet standards. Flowing stripes, a natural work of art Natural zebrawood grille The front cover of the FT7 grille is made of zebrawood sourced from West Africa from trees that normally grow at an altitude of 1,600 meters. Its grain resembles the flowing patterns of a zebra, a dynamic animal that well represents the unique wilderness of the West African highlands. Each grille strip is precisely aligned with the magnet positions, resulting in a reduction in sound wave interference caused by reflections from the grille. Balanced energy, even power Patented uniform magnetic field design Finite element analysis shows that conventional rectangular magnet designs have uneven magnetic fields, with some areas particularly strong and others weak. This results in uneven forces acting on the voice coils within the magnetic field, which can cause the driver to fail due to uneven movement and thus lead to distortion. The FT7 is equipped with FiiO's patented acoustic technology – the Uniform Magnetic Field Design. Through the optimized arrangement of the magnetic circuit and the use of magnets with rounded corners, FiiO is able to achieve a uniform magnetic field that ensures that all parts of the planar driver diaphragm are evenly loaded. This reduces driver breakup and minimizes distortion. Patent No.: ZL202420884963.1 Thanks to the patented uniform magnetic field design, the magnetic field area is expanded. This not only contributes to the high sensitivity of the FT7's large 106 mm driver, but also helps to reduce the weight of the driver, thereby improving wearing comfort. Each driver in the FT7 features 18 powerful N52 neodymium magnets with a magnetic flux of up to 1.5 T. The magnets provide ample energy reserves for excellent transient response and structured bass. 5-40kHz wide frequency response, hear every detail Flagship quality, but easy to carry, weighing 427g Comfort is something FiiO has always paid attention to. Although the FT7 has a large 106mm planar driver, it weighs only 427g, which is exceptional among high-end planar headphones. Large carbon fiber housing No expense has been spared to reduce the weight of the headphones as much as possible. As a result, much of the headphones are made of lightweight, high-strength carbon fiber, making the FT7 comfortable to wear even during long listening sessions. Cryogenic treatment at -192°C Liquid nitrogen-frozen monocrystalline copper cable A new cable made from over 6N OCC (99.99998%) high-purity monocrystalline copper has been specially developed and tuned for the FT7 and its sound characteristics. The copper undergoes a 7-day low-temperature treatment with frozen nitrogen at -192°C. This accelerates the breakdown of internal stresses in the metal material and the alignment and narrowing of the crystal boundaries to improve electrical conductivity and signal transmission. This ensures that free electrons can flow smoothly from one atom to another in the conductor, improving sound quality. In addition, PFA with a dielectric constant of only 2.1 is chosen as the insulating layer for the cable. PFA has damping and shock-resistant properties that can also contribute to the sound image. Planar headphones generally have high resolution but tend to sound a little “dry.” The PFA insulating layer not only preserves the high resolution of the single-crystal copper wire, but also helps to adjust the mid and low frequencies, adding a touch of richness to the sound for a relaxed and enjoyable listening experience. Cable specifications: Conductor cross-sectional area: 4x21AWG Conductor material: 6N OCC (99.99998%) High-purity monocrystalline copper Conductor structure: Axially twisted Insulation material: PFA Dielectric constant: 2.1 Inner jacket: TPU Outer jacket: Nylon Length: approx. 3m Cable outer diameter: Approx. 7.5*4.5 mm A rich listening experience Two sets of ear pads included The FT7 comes with two sets of ear pads, each offering a different sound.

Two adapters are also included: 4.4 mm to 6.35 mm adapter 4.4 mm to XLR-4 symmetrical adapter. Included headphone storage bag The included storage bag is made of Yaoli linen, which is comfortable to carry thanks to its soft texture and exudes subtle luxury thanks to its gentle sheen. It is densely woven, wear-resistant, and does not crease. Hi-Res Audio certified The FT7 has been certified as Hi-Res Audio capable by the Japan Audio Society (JAS) and the Consumer Electronics Association (CEA). This is proof that the headphones are capable of reproducing audio signals faithfully and accurately, just as they were intended to be heard. What`s in the box:FT7 Headphones*1 Linen storage bag*1 Headphone cable*1 Symmetrical XLR-4 plug to 4.4 mm jack adapter*1 4.4 mm to 6.35 mm adapter*1 Sheepskin ear pads*1 pair (pre-installed) Suede ear pads*1 pair FT7 box* 1 Quick start guide*1 Specifications: Open planar headphones Frequency response: 5Hz-40kHz Driver: 106mm proprietary planar driver Impedance: 25Ω±15% Headphone sensitivity: 94dB/mW@1kHz / 110dB/Vrms@1kHz Weight: Approximately 427g (without cable) Ear pad pressure: 4.2N±0.3N Cable material: 6N liquid nitrogen-frozen monocrystalline copper cable Cable length: Approximately 3m Headphone cable connection: Double 3.5mm TS audio plug: 4.4mm symmetrical

Hybrid 13-driver flagship in-ear headphones 1DD, 4BA and 8EST design on each sideEight electrostatic Sonion drivers Four custom Knowles BA drivers Dynamic driver with 10mm lithium-magnesium alloy diaphragm Electronic and physical five-way crossover Patented S.Turbo acoustic design Titanium construction with gold, silver and copper cables Exclusive serial number nameplate Three interchangeable Termination audio plugs included 22 Pairs of Ear Tips including SpinFit, FiiO HS18 and FiiO HS20 TipsHi-Res Audio CertifiedWhat you have in front of you now is the masterpiece of FiiO acoustics. This custom-built acoustic device is the result of 18 years of acoustic experience. It combines the best acoustic technology, embodies an unobtrusive design aesthetic and interprets the ideal sound in your heart. The essence of 18 years is united in a creation in which all sounds flow together, just for you. 1DD 4BA 8EST design per side To achieve the best possible sound quality, the FX-17 features a design with one dynamic driver, 4 balanced armature drivers and eight electrostatic drivers per side. A five-way crossover has been precisely tuned to balance the energy distribution between the drivers and ensure that each unit operates in its optimum state, resulting in a wider soundstage and a more natural sound. Eight electrostatic drivers for a truly airy feel Electrostatic drivers have exceptional high frequency extension, easily reaching 50 kHz, and a feeling of airiness, giving the listener a wider soundstage. The downside is that their sensitivity is only 99 dB/mW, which is low compared to the 110 dB/mW sensitivity typically found in balanced armature and dynamic drivers, resulting in a masking effect. Therefore, the FX-17 uses 8 electrostatic units to increase the sound pressure level and make the electrostatic drivers audible as they handle the high and ultra-high frequencies above 6kHz and are not just for decoration. * The masking effect refers to the phenomenon that the sensitivity of human hearing to high frequency signals is reduced in the presence of loud low frequency signals. Four customized Knowles BA drivers The FiiO FX17 uses 2 Knowles Balanced Armature drivers, which are responsible for the mid and high frequencies. Each of the composite balanced armature driver units is divided into two parts, with one part responsible for the mids and the other for the mid and high frequencies. This results in denser mids and a more transparent sound and allows a seamless transition to the electrostatic drivers. To achieve higher vocal performance at flagship level, FiiO has developed a specially designed Midrange Enhanced Balanced Armature Unit in collaboration with Knowles. The rear cavity of the Balanced Armature drivers has been designed with acoustic ports that provide more energy to the Balanced Armature Unit in the midrange to further exploit the benefits of the driver. The overall result is lush, smooth vocals that make the singer's seductive voice seem as if it's really right next to you. Dynamic driver with lithium-magnesium alloy High-resistance material surpassed only by beryllium The lithium-magnesium alloy is light, stiff and has a density of 1.6 g/cm3 - an ideal material for the diaphragm of a dynamic driver, surpassed only by beryllium. When reproducing high-frequency signals with fast vibrations, the lithium-magnesium alloy diaphragm has excellent mechanical properties thanks to its high internal damping, resulting in significantly lower natural frequency resonance and distortion. The distortion must not exceed 0.2%, which enables a really clean sound. The patented acoustic design of the S.Turbo Inspired by the turbos in super sports cars, the FiiO Acoustic Center has carefully developed the patented S.Turbo acoustic design. It cleverly channels sound through a turbo-shaped structure to boost the bass and make it robust and deep. At the same time, excess mid and high frequencies are filtered out of the dynamic driver to ensure a smooth transition between low, mid and high frequencies for a powerful and full sound. Resonant cavity, acoustic balance The rear cavity of the FX17 has been optimized for better sound. By damping with ports that are half the diameter of 0.2 mm, the FX17 precisely controls the airflow to achieve balanced air damping between the front and rear cavities of the dynamic driver. This not only improves the Q-factor and amplitude of the dynamic driver, but also increases the extension of the low frequencies and the clarity and transparency of the mid frequencies. Electronic and physical five-way crossover On the FX15s there is a switch to turn the electrostatic drivers on and off, proving that they are not just for decoration but are also important for a wide high frequency range. Many audiophiles have already experienced the high-resolution travel that electrostatic drivers are capable of. The FX17 increases the number of electrostatic drivers responsible for handling frequencies above 6 kHz to 8 per side, reducing power requirements. The FiiO FX17 also uses a five-way electronic and physical crossover with two systems to precisely control the drivers. This not only ensures a smooth frequency response curve, but also a flat impedance curve for wider customization. Such a crossover ensures a balanced energy distribution and smooth transitions between the drivers, both at low and high volumes. Pure titanium construction The FX17 is characterized by a minimalist aesthetic, with a classic and naturally curved cavity. The FX17's ear cup cavity is made from high-density, high-strength titanium, precision milled from a single block and carefully polished by hand. It is treated with Vapor the Position, which hardens the surface and gives it a glossy finish that creates a beautiful interplay of light and shadow. Flagship-level optimized wearing ergonomics Sonic nozzle precisely adjusted by 10° - Based on user feedback and scientific research, engineers precisely increased the angle between the sonic nozzles and the wearing surface by 10° along the Y-axis, while keeping the nozzle length unchanged. This allows the IEMs to enter the ear canal at an angle that significantly improves comfort and wearing stability. Comfortable and snug fit - The new rear ear cup design features a 3D shape, especially in the auricle area. Engineers have conducted hundreds of tests and optimizations to develop a 1.4 mm thick filling protrusion to match the human ear, making the IEM fit more secure and comfortable. Reduced pressure on the ear - The new design of the posterior cavity has a reduced thickness of approximately 1 mm in the area of the folded shell of the human ear. This design significantly reduces the pressure of the IEM on the ear. In combination with the excellent shell design, the feeling of foreign objects in the ear is eliminated, so that it feels as if there is nothing there. Mixed gold, silver and copper cable Three different transmission materials are used for the FX17's cable - gold, silver and copper - to utilize the strengths of the different materials. Gold, silver and copper are forged at over 1000 degrees and then refined into crystalline single crystals to remove impurities and reduce transmission loss. Each of the three elements has its own advantages, which together lead to significantly improved sound quality. Gold - Its high conductivity and low resistance result in faster signal transmission, which enhances bass transients for a truly rippling, powerful sound. Silver - It is more sensitive in the transmission of high frequency signals. It is characterized by fast transmission speed, low losses, better resolution and ultimately higher resolution. Copper - is characterized by warm and soft voices. It helps to create a relaxed and natural sound and delivers a wonderfully natural sound image. Three interchangeable in-line audio plugs with twist lock Three interchangeable audio plugs are included with the FX17: 3.5 mm single-ended, 4.4 mm balanced and the Type-C plug with integrated digital decoding and DSP, so you can enjoy high quality audio regardless of the connected device. The interchangeable Type-C connector features an integrated DSP audio decoding chip that supports high-resolution PCM up to 32-bit/384 kHz and a balanced output. It also supports a high-precision 8-band PEQ. Using the algorithm developed by FiiO and the FiiO Control APP or the web interface, the PEQ can simulate or correct the frequency response curve of the headphones. You can also export, import, share and save EQ curves. Output power: 2x55mW at 16Ohm, 2x30mW at 32Ohm Crosstalk -110dB Noise floor <0.8µV Distortion <0.001% SNR <122dB Hi-Res Audio certified The FiiO FX17 is Hi-Res Audio certified as defined by the Japan Audio Society (JAS) and the Consumer Electronics Association (CEA).

Dynamic in-ear headphones 10 mm polymer composite diaphragm Dual-cavity design 0.033 mm Japanese CCAW voice coil External high-power N52 magnet High-purity oxygen-free copper cable In-line control with microphone included Independent DSP chip 6 built-in tuning presets Supports lossless 384 kHz/24-bit audio decoding High Res Audio certified 10 mm polymer composite diaphragm To set the benchmark for entry-level sound quality, the JD10 features a carefully selected 10 mm polymer composite diaphragm. This cone is characterised by high rigidity, low distortion and optimal damping. It delivers a rich and full bass that blends perfectly with the mids and highs to create a really pleasant sound. In addition, thanks to careful acoustic tuning that utilises the cone's stiffness, the JD10 is high-resolution in a way rarely found among its competitors and capable of reproducing even subtle audio details. Dual cavity design The JD10 utilises a dual acoustic cavity design with separate damping control systems in each cavity. This precise control of airflow damping helps to reduce distortion, effectively improving driver cone movement and bass response. When listening to complex music, this design allows the JD10 to capture more nuance in the bass notes - resulting in refreshingly fast and detailed bass. 0.033 mm Japanese CCAW voice coil To achieve higher sound quality from the driver, the JD10 uses a special ultra-fine Japanese CCAW voice coil with a wire diameter of only about 0.033 mm. This voice coil significantly reduces the overall mass of the driver thanks to the thinness of the wires and the properties of CCAW. This makes it easier to get the driver to produce higher volumes and also results in an improved impulse response. The result is a clearer and more pleasant sound. External N52 high-performance magnet The JD10 uses an external magnet design. This allows a larger magnet to be used, which surrounds the voice coil more effectively and produces a more powerful sound. N52 high performance neodymium-iron-boron magnets were chosen for their high energy density and ability to deliver their power over a uniformly wide range to ensure optimum driver performance. 3.7g light The JD10 was designed from the ground up to be a comfortable and lightweight, versatile pair of in-ear headphones.

The aluminium alloy middle frame provides sturdy support and protection for the display. The plastic back cover was chosen for its light weight and also serves as the battery compartment. The back cover has a bevelled surface for a better grip. Entry-level price, premium configuration The 680 processor is considered a low-end configuration compared to FIIO's mid-to-high-end products (and even the broader music player industry).In this case, it is a low-end device equipped with a high-end processor. Two CS43198 DAC chips are standard configurations for mid-range portable audio products. Some users may compare them to portable USB dongles and assume that their sound quality is similar. However, the two are fundamentally different. One very important point is that the music players have a built-in battery, whose power source and flexibility is much higher than USB dongles, which draw their power from smartphones. This is one reason why the JM21 can deliver up to 700 mW of output power. Another point is the digital audio signal path, the player uses the main control chip and FPGA to reduce jitter before the DAC conversion, ensuring a direct signal path with a high correlation to the quality of the source. In contrast, portable USB dongles rely on the USB transmission from the phone via a cable for decoding and amplification, introducing additional factors that can affect the audio signal. Various connections and functions The 3.5mm and 4.4mm headphone outputs also serve as line out (LO) outputs, allowing you to connect external amplifiers or powered speakers. In terms of digital outputs, the JM21 supports coaxial and USB digital audio output, providing a digital audio source for connection to higher-quality decoders. For the coaxial output, you should use a 3.5mm to RCA adapter, with a maximum sample rate of 384kHz or DSD128. The USB output supports up to 768kHz or DSD512 in exclusive USB audio mode in the FiiO Music App. Internally, the JM21 is equipped with two customised femtosecond oscillators that ensure sufficient quality for digital transport. These features make the JM21 a versatile device that can serve multiple purposes and meet different user needs. Worry-free purchase, effortless use Meeting the needs of users has always been FIIO's primary mission. To achieve this, the JM21 not only comes with excellent product configuration and portability, but also with well-thought-out accessories to provide users with hassle-free use. For example, the JM21 comes with a pre-installed PET screen protector and a transparent protective case for comprehensive protection, so you can use the product immediately after unpacking it without worry. *Please note: the FiiO JM21 does not support fast charging. It is recommended to use a USB charger with max. 5V-2A for charging.

One very important point is that the music players have a built-in battery, whose power source and flexibility is much higher than USB dongles, which draw their power from smartphones. This is one reason why the JM21 can deliver up to 700 mW of output power. Another point is the digital audio signal path, the player uses the main control chip and FPGA to reduce jitter before the DAC conversion, ensuring a direct signal path with a high correlation to the quality of the source. In contrast, portable USB dongles rely on the USB transmission from the phone via a cable for decoding and amplification, introducing additional factors that can affect the audio signal. Various connections and functions The 3.5mm and 4.4mm headphone outputs also serve as line out (LO) outputs, allowing you to connect external amplifiers or powered speakers. In terms of digital outputs, the JM21 supports coaxial and USB digital audio output, providing a digital audio source for connection to higher-quality decoders. For the coaxial output, you should use a 3.5mm to RCA adapter, with a maximum sample rate of 384kHz or DSD128. The USB output supports up to 768kHz or DSD512 in exclusive USB audio mode in the FiiO Music App. Internally, the JM21 is equipped with two customised femtosecond oscillators that ensure sufficient quality for digital transport. These features make the JM21 a versatile device that can serve multiple purposes and meet different user needs. Worry-free purchase, effortless use Meeting the needs of users has always been FIIO's primary mission. To achieve this, the JM21 not only comes with excellent product configuration and portability, but also with well-thought-out accessories to provide users with hassle-free use. For example, the JM21 comes with a pre-installed PET screen protector and a transparent protective case for comprehensive protection, so you can use the product immediately after unpacking it without worry. *Please note: the FiiO JM21 does not support fast charging. It is recommended to use a USB charger with max. 5V-2A for charging.

You can directly feel how every touch gets you to your destination easily and quickly. Discrete Class AB transistor current amplifier Headphone amplifier A key component of the K17 is a carefully designed, fully discrete amplifier circuit for headphones. The discrete circuit is designed as an OP+ transistor current amplifier and is equipped with the classic pair of ON semiconductor transistors MJE 243/253. They are capable of generating high currents with low output impedance. The result is an output power of up to 4000mW+4000mW in balanced mode, almost twice as much as the K9 Pro ESS. It is capable of driving various types of headphones and in-ear headphones with ease, producing a smooth, pleasant and natural sound. AKM flagship DAC AK4191+ 2x AK4499EX The K17 features AKM's flagship DAC chip combination - AK4191+2xAK4499EX.

This ensures both a high dynamic range of the signals and significantly reduced crosstalk. Various parts of the audio circuitry, including the I/V converters and LPF stages, use multiple OPA 1612 low-noise precision operational amplifiers to ensure dynamic audio output. Physically separated circuit boards The different sections of the internal power supply, digital and analog sections are all located on physically separated circuit boards to avoid interference between them. This ensures the accuracy and integrity of signal processing for a purer and cleaner audio output. Precision power supply design Linear 35W high noise power supply with five large 4700µF electrolytic capacitors. The K17 is powered by a high-quality, low-noise transformer that ensures the purity of the power delivered. In addition, five 4700µF electrolytic capacitors provide ample power reserves to ensure a consistent power supply. Separate power supplies for analog and digital circuits Separate power supplies for the digital and analog circuits effectively prevent crosstalk and interference between them. Multi-stage analog power supply The analog audio circuitry of the K17 is powered by a multi-stage power supply. Many of the stages have their own power supply circuitry, including those for the digital-to-analog conversion, LPF and transistor. Low noise, high power supply rejection ratio (PSRR) The TPA7A47/7A33 LDO regulators also act as secondary voltage regulators to continuously deliver stable and clean performance. Precisely restored audio where every detail is audible 3 ACCUSILICON femtosecond audio crystal oscillators with low phase noise The K17 uses three industry-leading ACCUSILICON femtosecond crystal oscillators with extremely low phase noise, including the AS318-L (45.1584Mhz, 49.1520Mhz) and the AS318-Pro (24.575Mhz). This significantly reduces the effects of phase noise on audio signals, allowing audio signals with different sampling rates to be accurately and faithfully restored, resulting in a purer and more consistent sound. Dual core design smooth stable experience Powerful X2000 multicore processor: The processor features a unique design consisting of a small XBurst@ main core.

  FiiO K9 Pro ESS - Desktop headphone amplifier at its best   The FiiO K9 Pro ESS stationary headphone amplifier in summary: The FiiO K9 Pro is probably one of the most versatile devices in the entire range, even if you might not think so at first glance. Not only does it contain a top-class DAC, but also a first-class Bluetooth receiver and a powerful amplifier in its elegant and unobtrusive housing, which together provide excellent sound from a wide range of sources. The whole thing is then controllable via app or directly via the front on the device. Either way, the FiiO K9 Pro is a lot of fun!   The highlights of the FiiO K9 Pro at a glance:         Always high quality connection - via Bluetooth 5.0, optical, coaxial, USB and more       Extremely connectable - a multitude of analogue and digital connections       Separate, yet powerful together - analogue and digital sections separated       Fully balanced design - powerful and low-noise thanks to THX-AAA       Operable via app - volume, channel balance, sleep timer and more     Ready for a permanent connection - Wireless via Bluetooth 5.0 and more   The flexibility of Bluetooth...       The Bluetooth protocol has evolved steadily since its development more than twenty years ago, and with its current version 5.0, it has truly "grown up". The progress compared to the previous Bluetooth version alone looks brilliant: Double the transmission speed, four times the range and eight times the amount of data that can be transmitted simultaneously.   However, the underlying Bluetooth version is "only half the battle", after all, the corresponding Bluetooth codecs must also be supported so that the music travels in high quality. This is not a problem in the FiiO K9 Pro, as SBC, AAC, aptX, aptX LL, aptX HD and LDAC are available here. This makes the FiiO K9 Pro both up to date and backwards compatible with virtually all Bluetooth-enabled devices on the market.   ...and the uncompromising nature of wired connectivity in harmony     Bluetooth today delivers remarkable sound quality and is therefore fully supported, but on the input side, FiiO prefers to rely on "traditional ways". A whole range of analogue inputs (stereo RCA, 4.4 mm jack), digital inputs (optical, coaxial and USB) and outputs (stereo RCA, balanced 3-pole XLR output and 4-pole XLR output, 4.4 mm balanced jack and 6.35 mm jack) are available as classic connection options.   Or in other words: Everyone can find a connection here. Analogue and digital, balanced and unbalanced. And the best thing about it: You decide for yourself whether you want to use the FiiO K9 Pro as an analogue headphone amplifier, as an analogue preamplifier or "only" as a high-quality D/A converter. At the touch of a button.   Huge format variety - you press play, and the K9 Pro does the rest.       The 2 x ESS 9038Pro digital-to-analogue converter chip built into the FiiO K9 Pro is already something of a legend in its field. It convinces with its high degree of transparency and resolution, paired with high dynamics and extremely low noise values.     But not only with this, but also with the multitude of supported bit rates and resolutions. Whether it's PCM at up to 32 bits and 384 kHz, studio quality with MQA or native DSD256, you simply press play and the DAC proves that its legendary status is well deserved.   Uncompromising amplifier technology and balanced construction - THX AAA™.     THX AAA™ stands for "Achromatic Audio Amplifier", which is an amplifier technology that is virtually free of sound coloration of any kind. And the almost unavoidable background noise and distortion in the sound image are also reduced to an absolute minimum.     Also good to know: The AAA™ technology has been specially designed, developed and optimised for use in combination with headphones and impresses with gigantic power values of up to 2 watts when low impedance headphones are operated. And it's completely free of distortion!*     At the same time, the FiiO K9 Pro has a strictly balanced internal design, ensuring extremely low noise and preventing the two channels from "getting in each other's way". And this continues with the analogue and digital sections...     *Tested in the FiiO test lab on the balanced output.   Work is done separately - To achieve the goal together     Namely: outstanding sound. And in order to achieve this, not only do the components that process the sensitive music signal work in a separate area of the circuit board from the power supply, which is manufactured according to FiiO specifications, but the digital section itself is also separated from the analogue section on the circuit board.     And that's not all! Because the analogue section and the digital section are both supplied with power separately from each other, so that there can be no interference with each other. All that remains is sound of the highest quality.   Everything under control - with the handy FiiO Control app.     Especially when playing music from your smartphone or tablet, you'll appreciate the benefits of the FiiO Control app, available for iOS and Android. You can easily control the volume via Bluetooth, adjust the channel balance, configure the sleep timer and much more. And of course, all this also works when the K9 Pro is not playing music via Bluetooth, but via one of its other inputs.   Convincing "hands-on" as well - with the volume control and the buttons     And those who prefer "analogue" will be pleased with the numerous setting options directly on the front. For one thing, there is the rotary volume control, which is not only softly illuminated (the colour changes depending on the sampling rate) and has a high-quality feel, but also controls the volume precisely. And in doing so, it makes channel imbalances in volume and noise virtually impossible.     And there are a whole lot more sensible controls. Buttons for the 3-stage gain (the amplification factor with which the headphones are to be driven), the input selection as well as the selection of the operating mode; headphone amplifier, DAC or pure preamplifier.     No matter what you end up using the FiiO K9 Pro as, one thing is certain: you'll have a lot of fun with it. Guaranteed.
