Bluetooth on-ear headphonesRetro ear cups with woodBluetooth 6.0High-resolution 40 mm dynamic driverSemi-open designLDAC supportUp to 30 hours of battery lifeLightweight and portable 92 g designSupports app controlReplaceable ear padsExpression of retro-futurism aestheticsThe exterior pays homage to the classic design of the mini on-ear headphones of the 1980sThe sleek design offers a transparent view of the inner workings and complements the small wooden ear cups with real buttons, creating a unique aesthetic where nostalgia and futurism meet. The perfect vintage accent for your look.High-resolution 40 mm dynamic driverThe audio quality is in no way inferior to the styleFiiO has solved the problem of frequency loss in the low frequency range, typical of classic on-ear models, by incorporating a bass-optimized driver in the EH11. The audio quality of these on-ear headphones is anything but “retro” and offers much more than just adequate sound. Fiio has chosen a 40 mm long-stroke driver with a highly damped composite diaphragm to lower the resonance frequency to 65 Hz. This gives the EH11 powerful, dynamic bass that extends down to 17 Hz and covers the entire spectrum of low-frequency instruments. You'll experience sharper attack and decay on drums, as well as excellent instrument separation and multi-layered depth when enjoying complex classical pieces.Semi-open designVentilated comfort and minimized sound radiationThe semi-open design of the headphones, with ventilation holes and damping filters, eliminates the “stuffy” feeling typically associated with closed headphones. The result is a more natural and transparent sound. Compared to fully open headphones, the damping system controls airflow to minimize sound radiation.LDAC support for high-resolution BluetoothNear-lossless audio qualityThe EH11 supports the high-resolution Bluetooth encoding format LDAC*. With a transfer rate of up to 990 kbps, which is about three times that of standard Bluetooth formats (SBC/AAC), LDAC transmits significantly more raw audio data during transmission, resulting in near-lossless sound quality. As one of the few Bluetooth codecs for wireless transmission to receive Hi-Res Wireless certification, it is widely recognized in the industry as a high-quality, high-resolution Bluetooth standard.*To use this feature, your source device (phone) must support LDAC output. Due to the larger amount of data transmitted, using LDAC results in slightly higher power consumption. The format is enabled by default but can be disabled via the FiiO Control app.Long battery life of up to 30 hoursUninterrupted music playbackCharge the device for just 2 hours and enjoy up to 30 hours of playback time. Say goodbye to worrying about short battery life and enjoy music wherever you go.Portable and lightweight designTake the EH11 with you anywhere without any hassleWeighing only about 92 g and with a gentle clamping force of only about 1.7 N, these headphones are so light that you can hardly feel them on your head, allowing for fatigue-free long listening. Enjoy the feeling of music floating around your ears with cloud-like comfort.No interruptionsSupports simultaneous connection of two devicesThese headphones can stay connected to two Bluetooth devices at the same time, such as your PC and smartphone, so you can switch seamlessly between watching series and playing games.

Closed-back headphones Natural purpleheart wood Large dynamic 60 mm driver Diaphragm made of wool composite nanofiber wood W-shaped diaphragm Closed design U-shaped damping tube Low impedance, high sensitivity, easy to drive Furukawa monocrystal copper + silver-plated, oxygen-free copper braided cable Lambskin/suede ear padssuede included 4 detachable audio plugs included Yaoli linen storage bag Naturally magical colors, gracefully enchanting purple The creation of the FT13's wooden ear cups Following the success of our FT1 wooden headphones, FiiO began searching for new types of wood to bring their unique appeal to more people. This time, FiiOs search led them to a “purple treasure” from the ancient rainforests of South America: purpleheart wood. This wood is not only exceptionally hard, but also captivates with its unique color. Over time, its light brown hue gradually transforms into an unforgettable, deep purple. Creating the vibrant wooden ear cups requires a blend of nature's magic and FiiO's meticulous craftsmanship. Purpleheart has been used for instruments, furniture, and other items since the 1920s. After a long journey from South America, the wood arrives in Lianyungang, Jiangsu, where it is stabilized in a hot oven and cut with precision. It is then stored for months in a dark room, where it slowly “develops” its fascinating wine-red color. This wood then undergoes a final, intensive process of selection, cutting, CNC carving, polishing, and varnishing before it is ready for the final product. Due to its rarity in nature, purple has long been considered a symbol of mystery, power, and individuality—with deep cultural significance. It is precisely this color, which ages beautifully over time, that is our inspiration. It allows us to perfectly express the original intention of our wooden headphone series—to blend into the natural world and age elegantly over time. Ear cups made from natural purpleheart wood Natural colors, solid and hard The headphone ear cups are made from purpleheart wood, a type of wood native to South America. To achieve its rich color, each piece of wood is left to age naturally for 90 days. Due to their individual characteristics, each wooden ear cup has a unique grain and color tone, making each pair of headphones truly one of a kind. The raw wood is first cut to size with precision using CNC milling. To achieve a perfect finish, FiiO then apply a high-gloss lacquering process in which the wood is repeatedly sanded, polished, and the natural pores and unevenness are filled until the surface is completely smooth. Finally, a final coat of high-gloss lacquer is applied, bringing out the unique, natural grain of the wood. With a density and hardness far exceeding that of ordinary woods, purpleheart wood is not only naturally corrosion-resistant, but also helps to minimize resonance in the headphone ear cups. The result is a faster and clearer sound. *This wood comes from the tropical rainforests of South America and is known for its stunning purple-brown color and superior strength. It is often used for high-quality furniture, musical instruments, and decorative items. Its unique color is not artificially applied, but is the result of natural oxidation. With prolonged exposure to light and air, the color of the wood gradually darkens, eventually taking on a deeper purple-brown or chestnut hue. Large 60 mm dynamic driver Enjoy deep bass and a wide soundstage Like the FT1, the FT13 features a massive 60 mm dynamic driver, a size that is almost unheard of in its category. This larger driver produces more power and converts electrical signals into sound more efficiently. The result is sound with less distortion, faster transients, and deeper, more powerful bass. Wool composite nanofiber wood cone European wood, honed from over 100 years of paper manufacturing expertise The new cone is made from birch wood sourced from the cold climates of Europe. The extreme cold makes the wood incredibly hard and gives it strong fibers. This unique property allows us to precisely tune the resistance and stiffness of the diaphragm during manufacturing to achieve our desired sound goals. Using the same traditional paper-making process as for the FT1 cone, a method that has been around for over 100 years and is still widely used by various hi-fi brands, the raw materials are processed into pulp through soaking, steaming, and beating. During this process, lighter and harder carbon fiber threads are added to increase the stiffness of the diaphragm and reduce unwanted breakage, improving detail in the high frequency range. The diaphragm is then baked and molded to a thickness of only 0.1 mm. By adding wool fibers to the paper diaphragm, FiiO take advantage of their natural flexibility to fine-tune the sound. This gives the finished diaphragm a uniquely natural and warm sound character that is both captivating and profoundly emotional. W-shaped diaphragm Proprietary acoustic technology for higher efficiency The headphones feature a W-shaped diaphragm design inspired by speaker diaphragms. Compared to the driver diaphragms typically used in headphones, this design increases the effective vibration area of the diaphragm by 25.8%. The diaphragm consists of a hard dome and a flexible surround. This rigid dome covers a larger surface area than conventional diaphragms, and since it is driven directly by the voice coil, less energy is lost during vibration transmission. Compared to a more flexible material, the hard dome has lower internal losses, resulting in higher efficiency and lower distortion due to driver breakup. Closed design Greater immersion through reduced noise, enjoy pure, quiet sound Beyond the natural isolation of its closed wooden ear cups, the FT13 features an integrated system of passive noise reduction components. These include a standing wave dissipation chamber, specially designed sound-absorbing cotton in the rear cavity, and a noise-reducing U-shaped tube. Together, these components can reduce everyday ambient noise by up to 26 dB. The closed design also prevents sound from escaping, making the headphones perfect for quiet environments such as offices, libraries, or dorm rooms without disturbing others. U-shaped damping tube An invisible hand that reduces resonance Inside the FT13, a U-shaped damping tube cleverly uses the air inside the headphones to tune the sound. The design of this tube has been carefully optimized to lower the resonance frequency of the cavity, resulting in deeper, higher-quality bass. Low impedance, high sensitivity, easy to drive Your entry-level headphones The impedance, sensitivity, and frequency response of the FT13 make it the ideal choice for listeners taking their first steps into the world of personal audio equipment. It pairs perfectly with popular, non-audiophile devices such as smartphones, tablets, and PCs. Experience high-fidelity sound in audiophile quality without having to invest in expensive or complex equipment. Large CCAW voice coil Lightweight, wide, powerful The FT13 features a CCAW voice coil imported from Japan with an ultra-thin 0.035 mm wire and a lightweight KSV body. These components significantly reduce the moving mass of the diaphragm, resulting in faster sound reproduction and less unnecessary reverberation. The voice coil has a diameter of 25 mm. In a fixed magnetic field and at constant current, a larger coil diameter means a longer voice coil wire. A longer copper wire thus results in greater driving force and higher efficiency, leading to a richer midrange and faster transients. Adjustable magnesium alloy headband Advanced materials, improved comfort The FT13 offers a significant improvement in headband comfort through comprehensive improvements in materials, aesthetics, and ergonomics. The outer U-shaped frame is now made of a strong and lightweight magnesium alloy that blends seamlessly into the design of the headphones. The ball-bearing slider features a high-quality design found in high-end headphones, offering a silky-smooth adjustment with clear feedback, while the swivel joints and connections are more robust than ever. The part of the headband that comes into contact with your head has been replaced with soft, durable lambskin leather, which is both more durable and breathable than the synthetic leather commonly used, providing greater comfort during longer listening sessions. Three-axis swivel mechanism Swivels as desired, freely adjustable After extensive ergonomic testing, FiiO implemented a three-axis adaptive swivel mechanism that continues the FT series' tradition of excellent ergonomics. This design not only ensures that the headphones comfortably adapt to different head sizes and shapes, but also allows for a perfect fit without sound leakage. Angled driver design Reduces standing waves for clearer sound In the FT13, the acoustic drivers are angled to run parallel to your ear canals, so the sound reaches your eardrums directly. This not only reduces the high-frequency drop you would get with a conventional design, but also minimizes standing waves inside the ear cups. The result is a much clearer, purer sound with less distortion. Furukawa monocrystalline copper + silver-plated oxygen-free copper Improved cable, improved sound This cable is constructed with an 8-strand braided design and contains a total of 1,000 conductor wires. It is a blend of 500 secondary-melted Furukawa single-crystal copper wire conductors and 500 oxygen-free silver-plated copper wire conductors, each with a polarity of 17 AWG. This combination of high-quality metals and advanced processing techniques enables the cable to deliver truly outstanding sound quality. Furukawa single-crystal copper Increases the richness and density of the midrange and improves bass quality, making the mid and low frequencies sound full and emotional. Silver-plated oxygen-free copper, the silver plating helps to improve the conductivity and high-frequency transmission characteristics of the copper, enhancing sound transparency with more detail and optimized overtones, as well as an expanded soundstage. Lambskin/suede ear pads Velvety texture, reliably durable Two types of ear pads are included, both of which feature a skin-friendly, breathable, and durable outer material. Inside the ear pads is a low-density, slow-rebound memory foam that conforms to the shape of the ear. Compared to the synthetic leather ear pads commonly used in headphones, these offer both greater comfort and a longer service life. The high-quality ear pads made of natural lambskin have a velvety smooth surface that is also breathable, sweat-resistant, and easy to clean. In terms of sound, these ear pads deliver detailed highs, clear and clean mids, and fast bass. The suede ear pads have a matte texture, are durable and flexible, yet cool and breathable. In terms of sound, these ear pads enhance the bass, add richness to vocals, and enhance the sense of atmosphere. Four detachable plugs included Wide compatibility The FT13 comes with four detachable audio plugs, allowing one cable to be used with different audio sources. Hi-Res Audio certified Reliably excellent sound The certification is not only proof that the headphones meet international standards, but also of our continuous pursuit of better sound quality. Yaoli linen storage bag Stylish and dust-proof, so you don't have to worry The headphones come with a high-quality Yaoli linen storage bag, which further enhances the ownership experience. With materials and workmanship that rival those of premium French brands, its exquisite quality and excellent texture provide special protection for your valuable device. 3 significant improvements Improved sound: Compared to the spruce wood diaphragm of the FT1, the FT13 features a birch wood diaphragm that is many times harder to improve the precision of the diaphragm. In addition, carbon fiber has been added to increase the stiffness of the diaphragm and reduce unwanted driver interruptions, resulting in higher treble resolution compared to the FT1. Improved cable: Compared to the FT1's silver-plated oxygen-free copper cable, the FT13's secondary-refined Furukawa monocrystal copper and high-purity oxygen-free silver-plated copper cables are an improvement in every respect.

In-ear headphones with a dynamic driverBeryllium-coated driverPure titanium housing, CNC-machinedCryogenically treated, silver-plated single-crystal copper cableDynamic driver with a 13.8 mm outer diameterW-shaped diaphragm with independent surroundAcoustic prism front chamberAirflow-controlled, damped rear chamberTwo interchangeable tuning nozzlesIncludes interchangeable plugs (3.5 mm/4.4 mm/TC)0.78 mm 2-pin detachable cableHi-Res Audio certifiedUltimate elegance – a new movement in soundThe History of the OAK SeriesThe new OAK series pays homage to the timeless craftsmanship of Audemars Piguet. We honor the watchmaker’s pursuit of perfection and translate this dedication into rock-solid build quality and an elegance that never fades. Where sound meets light, individuality and sophistication take center stage.OAK NANO is the first model in the OAK series, the spiritual successor to the FIIO FD7, and SNOWSKY’s first flagship product. The OAK NANO is the result of two years of research and development—a journey of ceaseless refinement in pursuit of jewelry-grade craftsmanship and an exceptional sonic character. The development team chose beryllium metal for the diaphragm—the same premium material found in the FD7. Its rare combination of lightness and rigidity ensures a distinctively clear and open sound character. Together with a series of sophisticated acoustic innovations, the OAK NANO transforms every listening session into a first-class audio experience.High-Quality Materials – Sublime Sound FidelityBeryllium Alloy DiaphragmThe OAK NANO inherits the acoustic DNA of the legendary FIIO FD7 and carries on the legacy of beryllium diaphragms while breaking new ground. As a driver material, beryllium is ultra-light, exceptionally rigid, and superior to aluminum or titanium. Its low damping and high sound velocity ensure no unwanted coloration, making it the top choice for high-end audio.While pure beryllium is becoming increasingly rare due to global supply chains, the OAK NANO utilizes a special beryllium alloy that mirrors the performance and sonic characteristics of the pure metal. FiiO has pushed the boundaries of precision engineering to reduce the thickness of the diaphragm and thus further exploit the material’s potential. This significantly improves high-frequency reproduction, transient response, and distortion control, enabling the precise reproduction of the finest details—from the crisp attack of percussion to the delicate nuances in vocals.Refined Sophistication – Timeless ElegancePure Titanium HousingThe OAK NANO utilizes pure titanium, prized for its density and hardness, to create a housing that remains flawless over time. Through a series of sophisticated and precise manufacturing processes, including mirror polishing, CNC machining, and PVD coating, its distinctive design language comes to life, showcasing the headphones’ unique color, luster, and sharp contours with impressive clarity.The conductor reimagined – The next level of sonic purity-192 °C cryogenically treated with liquid nitrogen, silver-plated single-crystal copper cableFiiO selects 6N OCC (99.99998% pure) single-crystal copper as the raw material. This ultra-high-purity conductor is naturally free of grain boundaries and offers exceptionally low resistance and high conductivity, while eliminating oxygen and hydrogen impurities that compromise signal integrity.To push electrical performance to its absolute limit, each conductor undergoes a 168-hour (7 full days) deep cryogenic treatment.At -192 °C, internal stresses in the metal are completely relieved, allowing the atomic structure to rearrange itself and form a more uniform, denser arrangement. This molecular restructuring ensures a more uniform flow of electrons, resulting in a remarkably clear and fluid sound—free from the harshness or “graininess” often found in standard cables.High-flux-density magnetic control – Unleashed dynamic power13.8-mm dynamic driver with external magnetBuilding on the legacy of the FD7, the OAK NANO features a larger 13.8-mm driver unit with a correspondingly enlarged and thickened magnet. A larger magnet means a stronger and more stable magnetic field. Laboratory tests confirm that the magnetic flux density in the voice coil gap reaches nearly 1.5 T, with distortion of only 0.1% even at 114 dB SPL. This immense magnetic force provides the necessary driving power for greater amplitude and minimal vibration distortion, resulting in outstanding transient response.*Test data from FIIO Acoustic LabsTailor-made – Excellence in Every DetailAdvanced dynamic driver designStarting with the acoustic characteristics of a single dynamic driver, FiiO spared no effort in refining the OAK NANO’s diaphragm, magnetic system, and voice coil—every detail is a deliberate step toward higher performance and a more refined sound.-Diaphragm thickness -50%Lighter, stronger beryllium dome tweeterIn the pursuit of perfection, FiiO has achieved the impossible: a larger beryllium dome that is simultaneously significantly thinner. Combined with FiiO’s newly developed high-flux magnetic circuit, the OAK NANO achieves lightning-fast transient response and breathtaking high-frequency reproduction.-Effective vibrating area +30%W-shaped independent surroundInspired by high-end home audio systems, the OAK NANO features a separate beryllium dome and a beryllium-coated suspension design that eliminates the weaknesses of conventional diaphragms. The result is a 30% larger effective diaphragm area and significantly greater energy reserves. Experience sound that is beautifully textured and undeniably powerful-Magnetic flux density 1.5 Tesla1.5-T high-flux external magnet designWith a dynamic headphone, everything begins and ends with the driver. The OAK NANO features a magnetic flux density of 1.5 Tesla, which significantly improves conversion efficiency and driver control. This high-flux environment effortlessly drives the diaphragm, resulting in a remarkably full-bodied and authoritative sound.-Pure Copper CCAW Voice CoilRefined High-Frequency SoundstageSpecially Selected Pure Copper Voice CoilWhile conventional single-driver designs often use lightweight copper-clad aluminum (CCAW) to enhance detail, the OAK NANO takes a more refined approach. Since our beryllium dome naturally offers high resolution in the high-frequency range, we opted for a pure copper voice coil to balance the sound character.This choice lends the sound a rich, soft warmth and a gentle, organic timbre—resulting in a deeply emotional and fatigue-free listening experience.Precision Correction – The Sound Stays on TrackAcoustic Prism System in the Front ChamberThe OAK NANO utilizes an advanced Acoustic Prism to ensure your music stays “on track.” This technology, proven in the acclaimed FD7, corrects the phase of sound waves as they travel through the chamber. By eliminating time delays and standing wave distortions, it enables superior control over every frequency, resulting in a refined sound.Precise airflow control – transformed mids and bassAirflow-controlled, damped rear chamberUsing micro-precise CNC machining, a high-density acoustic damping grid has been integrated into the vent openings of the OAK NANO’s rear chamber to regulate internal airflow. This special damping effectively suppresses resonances, resulting in deeper and more impactful bass. The midrange also benefits, with noticeable improvements in richness and density in the 100 Hz to 4 kHz range. The result is a fuller, more satisfying midrange and bass across the board.Two sound profiles – Discover a new sound at any timeTwo interchangeable tuning nozzlesThe OAK NANO features interchangeable tuning nozzles, including both red and black acoustic filters, to offer advanced tuning options. Each tuning nozzle features different densities of damping material to offer a total of two distinct sound profiles that match your personal listening preferences. Red nozzleMaster of atmosphere. Deep, present bass foundation with a powerful sense of space. Perfect for pop, rock, and folk.Black TipPrecise and detailed. Crystal-clear transparency with bright, detailed high-frequency reproduction. Perfect for classical and instrumental music.Seamless compatibility – tailored to your needsDetachable cable and interchangeable plugsThe OAK NANO was designed for ultimate flexibility. With a fully detachable cable and an interchangeable connector system, it effortlessly adapts to any listening environment. The package includes three interchangeable connectors to cover all your devices. Of particular note is the Type-C connector, which unlocks a variety of real-time adjustment options—giving you the flexibility of multiple setups in a single device.3 interchangeable connectors8-band precision PEQThe OAK NANO comes standard with 3.5mm single-ended, 4.4mm balanced, and Type-C DSP connectors for digital decoding.The Type-C connector houses a BES3001-SP DSP audio decoding chip with a balanced output, supporting the decoding of high-resolution 32-bit/384 kHz PCM audio as well as an 8-band precision PEQ setting.
