FiiO FT1 Pro Headphones

Here we have a nice pair of FT1 Pro headphones from FiiO who started out in 2007 producing portable speakers and headphone amplifiers. Our examples are in very good condition with original packaging, storage case, manual, cables, adaptor and our standard three month warranty.
FiiO Say….
The FT1 Pro is equipped with FiiO’s second generation, self-developed planar driver technology. The planar driver has been designed from the ground-up by FiiO, from the diaphragm, to the patented dual-coating, to the conductive trace width, to the fine-tuning of the magnetic circuit, and even the standardized bracket fixings – all to ensure a true quality driver.
Compared to typical off-the-shelf drivers, the self-developed driver can be completely customized to build and fit around it a sophisticated acoustic system – allowing it to be both light weight and capable of great sound quality.
While it weighs only 374 g, the FT1 Pro packs a capable 95 x 86 mm driver with specs rivalling that of flagship planar headphones.
Thanks to this intensive research and development, the FT1 Pro features a large, almost limitless soundstage rarely found among its peers. It also effortlessly produces sound up to 40 kHz.
Engineers have constantly strived to achieve thinner and lighter diaphragms for planar drivers. After two years of independent research and development, we have created for the FT1 Pro a class-leading 1 μm ultra-thin diaphragm, using high-performance PET as the substrate. The difference between even a 2 μm and a 1 μm diaphragm thickness results in noticeable performance differences when the diaphragm is vibrating at high speeds, which ultimately affects sound quality. The FT1 Pro’s 1μm ultra-thin diaphragm is exceptionally lightweight, allowing it to respond with lightning-quick speed. It faithfully reproduces even subtle sounds in the ultra-high frequency range, as well as providing exceptional dynamic range.
The FiiO FT1 Pro employs a newly self-developed technology for its planar driver – a patented dual-coating system. The planar driver uses high-performance PET as the diaphragm substrate and selectively applies sapphire and aluminum to create a dual-coated driver. Such a design enhances the driver’s frequency response across different frequency ranges, improves audio resolution, and allows listeners to fully appreciate the nuanced and unique sound quality of planar drivers. The first coating layer is made of aluminum. Lightweight and conducive, the aluminium coating enhances the traces’ conductivity, helping to reduce the driver’s impedance and power requirements as well as improve its dynamics. The second coating layer is made of sapphire. With its high hardness, the sapphire coating contributes to the diaphragm’s rigidity and enhances treble resolution and overall transparency, and helps the driver to exhibit a unique sound as a bonus.
The FT1 Pro is equipped with FiiO’s new patented acoustic technology – the uniform magnetic field design, which optimises the uneven magnetic field intensity caused by adjacent magnets and further expands the magnetic field range. This technology makes the FT1 Pro’s magnetic field more extensive, precise, and balanced, allowing the planar driver diaphragm in that magnetic field to be more evenly stressed. That is, the FT1 Pro planar driver diaphragm moves more evenly with reduced breakup and distortion – leading to a more refined sound that accurately captures even the subtlest of nuances in the music, which is characteristic of high-quality planar drivers.
In order to achieve high sound quality with the intricate second generation self-developed planar driver, the driver needs to be manufactured with precision at the nanometre level. Traditional diaphragm coating processes are not precise enough. To have its driver diaphragm manufactured with sufficiently high quality, the FIIO FT1 Pro’s driver is made
using a 28nm-grade process. This technique, inspired by coating technology used within the semiconductor industry, completely isolates the conductive traces material from the surrounding air. The traces material exists in a vacuum state at a pressure of 6.6 × 10⁻³ pascals, and the temperature is raised to 120°C. The traces material is transformed into
ionized particles, which then accumulate on an ultra-thin 1 μm film through charge attraction principles. This process creates the desired coating thickness for optimal acoustics and significantly enhances the durability and lifespan of the traces. Additionally, the FT1 Pro goes beyond industry standards by applying this complex and rigorous process twice to
each diaphragm, resulting in a dual-coated membrane design that delivers exceptional sound.
The lightweight FT1 Pro aims to bring great planar sound without requiring serious amplification. The low 20 Ω impedance combined with the high sensitivity of 112 dB/Vrms @ 1 kHz (or 95 dB/mW @ 1 kHz) means you can easily get great sound from the FT1 Pro.
The FiiO FT1 Pro is capable of a wide frequency response range from 7 Hz – 40 kHz, allowing you to truly experience even the subtlest of nuanced sounds the planar driver is capable of producing.
While the FT1 Pro features a large, double-sided magnet planar driver, it only weighs about 374 g – making it light, comfortable, and easy to carry around.
To make it more portable and lightweight, the FT1 Pro headband features high-quality steel slides, significantly enhancing the headband’s durability. You will feel the precision and sophistication of the mechanical design every time you adjust the headband. Additionally, compared to similar products, the FT1 Pro offers an extended adjustment range from 0 to 11 notches to accommodate various head sizes. The part of the headband in contact with the head is made of suede for a soft and comfortable wearing experience.
The FT1 Pro inherits the excellent ergonomic design of the FiiO FT series. The 3-axis adaptive headband allows for free
rotation at multiple angles. This design accommodates various head sizes and ensures a snug fit on the head for enhanced comfort and minimal sound leakage.
Experience comfortable long listening sessions and say goodbye to stuffiness. The FT1 Pro comes with breathable fabric earpads, featuring a textile material in contact with your skin. The high-density breathable mesh design efficiently dissipates heat buildup between the ear cushions and your ears. The side of the ear cushions is made of protein leather that both looks and feels good.
The FiiO FT1 Pro adopts the commonly used dual 3.5mm TS headphone connectors, allowing you to easily change and
upgrade to another headphone cable.
Included with the FiiO FT1 Pro is a stylish headphone storage bag made with the same techniques and materials as high-end French brands, rarely seen in its class but undoubtedly useful for protection.
The FiiO FT1 Pro comes with two headphone cables – terminated in 3.5 mm single-ended and 4.4 mm balanced plugs. Both cables are identically made using an oxygen-free copper-plated silver wire base with 392 wires, are of 24AWG thickness, and are 1.5 meters long. This makes the FT1 Pro widely compatible with many audio devices, as you can easily switch between the cables. They produce a transparent yet robust sound, allowing you to fully enjoy quality lossless audio.
