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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

The FIIO FT1 features two 3.5mm TRS headphone jacks, allowing you to easily switch and upgrade to a different headphone cable.

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.

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. This makes the FT1 compatible with many audio devices as you can easily switch between cables. They produce a transparent yet robust sound, so you can enjoy lossless audio quality to the full.
