This driver is part of the second generation of dynamic drivers in the FiiO FF series. Thanks to its science-based design, the FF1 driver's resonant frequency contributes to an extended, dynamic and textured bass for an overall more magnificent sound.Stunning sound - PU+beryllium-coated diaphragmThe driver and its diaphragm are the heart of an earphone, as this is where the sound is produced. Not only is the FF1's driver extremely rigid and lightweight with sufficient damping, but a special seal suspension system has been designed specifically for the FF1 to allow the driver to move better. This results in better quality and robust bass, sweet mids and vocals, for a sound that exudes atmosphere.The beryllium-coated diaphragm is very stiff yet lightweight, resulting in less unwanted driver break-up and therefore less distortion. Measured distortion: ＜0.2%@94dB (150~20kHz). The driver is also very responsive and offers excellent transient response.Hidden Advanced Acoustic Bass Resistance Tubes - Let the Sound FlowSound is created by the movement of air, and acoustic engineers focus on how to harness that air movement. For the FiiO FF1, the acoustic engineers designed a slim acoustic resistance tube that starts at the top of the FF1 earpiece and runs to the back. This hidden acoustic tube not only contributes to the FF1's elegant design, but also ensures that air can flow smoothly inside the earphones. Most importantly, the acoustic resistance tube can reduce the resonant frequency of the earbud housing and bass loss, so you can enjoy deeper and purer bass of high quality.Experience high quality bass When worn open, the FF1's effective frequency response extends to an astonishing 38 Hz, allowing listeners to become even more immersed in their music. For better bass performance, it is recommended to use the ear tips with sponge cover. Notes: Open wearing refers to normal wearing of the earplugs with sound leakage and no sponge cover.Nearly invisible when worn - Lightweight 3.2 gAs an affordable entry-level earphone, the FF1 is highly likely to be used in a variety of scenarios and over a long period of time - so FiiO needed to ensure the earphones were comfortable for long listening sessions. The FF1 weighs just 3.2g as a single earbud, making it almost invisible in the ears, ensuring excellent comfort during extended wear.Sport or leisure, HiFi is always with you - Supplied anti-slip silicone rings, silicone wing hooksIncluded with the FF1 are 3 pairs of anti-slip silicone rings in various sizes to ensure that the earphones stay comfortably in your ears, regardless of your ear size. Thanks to the FF1's open-wearing design, using the earphones is also suitable for activities such as hiking or cycling. Also included with the FF1 are a pair of silicone wing hooks that allow you to experience hi-fi while exercising. Communicate with the world with one button - Microphone with integrated controls.Scenario 1: The FF1 has inline controls that allow you to answer calls with just one button.Scenario 2: The FF1 is equipped with an HD microphone that allows for high quality calls.Scenario 3: The FF1 can be used as a hi-fi gaming headset, allowing you to exchange information with the HD microphone while fully immersed in the sound of the game.*The FF1 comes with a Type-C adapter cable that is compatible with many Android devices.0.78 mm 2-pin detachable cableThe FiiO FF1 features a detachable cable with 0.78mm 2-pin connector, paving the way for future upgrades to your listening experience.Great sound, tailor-made for you - 2 different sponge covers included.Included are 2 different sponge covers that allow you to tailor the sound of the FF1 to your exact needs. Open hole: transparent sponge cover, powerful bass, clear treble / Without hole: transparent sponge cover, powerful bass, lush vocals.

FiiO FF5Earbuds with detachable cable and carbon-based dynamic drivers     Large 14.2 mm dynamic driver     PU seal + carbon-based diaphragm     Extended acoustic bass resistance tubes     4-core, 392-wire silver-plated monocrystalline copper cable     Detachable MMCX cable     3.5/4.4 mm audio connector included     Open design     6 pairs of anti-slip rings included     Fine-tuned frequency response     CNC aluminium alloy construction Newly developed dynamic driver with carbon-based diaphragmThe FF5 is an earphone that departs from the traditions of its form factor and features a specially designed, large 14.2 mm dynamic driver with an innovative carbon-based diaphragm. The driver consists of a PU seal and a carbon-based diaphragm, which gives the driver a low weight and high rigidity. The result is a sound with fast transients and excellent treble resolution, as the driver's design minimises non-linear distortion by attenuating unwanted driver movement.The FF5's large 14.2mm dynamic driver delivers bass reproduction unmatched in quantity and quality by smaller drivers, with a sound that feels just right. Compared to the FF3, which focuses on the low and mid frequencies, the FF5 offers a faster sound with better separation. Thanks to the carbon-based diaphragm, resolution in the mids and highs is also significantly improved, resulting in more detailed and nuanced vocal reproduction.This is particularly noticeable with female vocals - when listening to music with a strong vocal emphasis, you can hear every last detail of the refreshingly lush voices.Beautiful like a blossoming flower - open designLike a flower in bloom with its many layers of petals, carefully tuned headphones can reveal many layers in the music.Inspired by petals, the FF5's design is both beautiful and functional. The FiiO development team wanted to reduce unwanted reflections and vibrations within the FF5's housing, which led to the creation of a diffuse open design with an acoustic damping device that allows some of the air pressure within the earphones to diffuse outwards - resulting in fewer unwanted internal reflections and standing waves, leading to cleaner sound and improved bass response.Amazingly large - Large 14.2 mm dynamic driverThe FF5 features an amazingly large 14.2mm diameter dynamic driver with a carbon-based diaphragm, chosen after much thought and experimentation. If the driver is smaller than 14.2 mm, bass performance will be negatively affected. However, if the driver is larger than 14.2 mm, the earphone becomes too large, which has a negative impact on wearing comfort. That's why we chose a 14.2 mm driver to strike a balance between high wearing comfort and stunning sound!Standard 4-strand 392-core silver-plated monocrystalline copper cable - Fully focused, with emphasis on female vocals.The FF5 comes standard with a silver-plated monocrystalline cable. 14 wires are braided together to form a small strand, and 7 small strands are braided together to form a large strand - giving 4 large strands with a total of 392 wires. More wires significantly increase the cross-sectional area of the wires in the cable, resulting in a higher transmission rate and stability. The strand braid reduces the skin effect, which further improves the transmission rate by increasing conductivity. Thanks to the above factors and the excellent materials, the FF5 cable has a significantly improved treble resolution compared to conventional cables, allowing for a very detailed and nuanced sound.  True freedom: Change whenever you want - Detachable cable, interchangeable plugs.We've found that there are very few earbuds with detachable cables, which severely limits the usability of these earbuds should something happen to the cable. The FF5 has a detachable MMCX cable that allows you to replace broken cables or experiment with different cables made of different materials.In addition, the FF5's cable is equipped with interchangeable audio plugs, so you can switch between the included 3.5mm and 4.4mm plugs at will to match your source!Advanced acoustic bass tubesEvery new product is an opportunity for new innovation! With each new generation of earphones, a lot of experimentation is done to ensure that the performance really is at least one step ahead of the previous generation. Compared to typical in-ear monitors, more care needs to be taken when designing an earphone to ensure great sound.After much experimentation, FiiO has developed acoustic resistance tubes for the FF5 that enhance and extend the bass response. When the driver's diaphragm vibrates, the resulting air pressure is redirected to these acoustic resistance tubes, reducing resonance in the lower frequencies so you can hear more extended and textured bass.Specially tuned frequency response curve"The frequency range of the female voice is between 160 Hz and 1.2 kHz. The FF5 was designed as a headphone that focuses on female voices rather than heavy bass. Therefore, a lot of attention has been paid to the representation of the frequency range and pitch of the female voice. We specifically controlled resonance at 127 Hz to prevent voices from sounding muddy and boomy, while we appropriately increased the frequency range from 2kHz to 4kHz to present female voices more clearly, transparently and prominently. Thanks to the light weight of the carbon fibre, the FF5 has excellent treble response, allowing the overtones of vocals, guitars, cymbals, violins and other instruments to come through clearly in a more nuanced and layered sound."--JosephChief Engineer of FiiO IEM's R&D Centre Less weight, more materials - 1CNC aluminium alloy construction.The FF5 is made from an aluminium alloy used in other high-end earphones to reduce weight while ensuring durability. A single ear unit weighs just 3.4g - so the FF5 simply disappears into your ear, leaving you fully immersed in your high-fidelity music.Attention to detail for great sound - Supplied anti-slip silicone rings.FiiO has always been a user-focused company. Some users prefer the use of non-slip silicone rings when using earbuds. Thanks to their feedback, the FF5 not only comes with three types of sponge covers, but also moulded anti-slip silicone rings. The total of 6 anti-slip silicone rings are available in sizes M/L and provide a better seal for an extended bass range, while maintaining high resolution in the other areas of the frequency response.SpecificationsWearing style: EarplugsDriver: Single dynamicFrequency response: 20Hz-20kHzImpedance: 45Ω@1kHzSensitivity: 106dB/mW@1kHzCable: 4 strands, total 392 wires high purity silver plated monocrystalline copper.Cable length: approx. 1.2 mWeight: approx. 3.4 g (without cable)Earphone connectors: extended MMCXAudio connector: 3.5mm SE/4.4mm balancedWide range of accessoriesItem NotesDetachable 3.5mm cable*1 Pre-installedDetachable 4.4mm cable*1   Tweeter sponge covers*6 pairs (open holes)   Balanced sponge covers*6 pairs (thin)   Bass sponge covers*6 pairs (thick)   Anti-slip silicone rings M*3 pairs (black)   Anti-slip silicone rings L*3 pairs (clear)   MMCX tool*1   Carrying bag HB1*1   Manual*1
