95x86mm FiiO-developed planar driver
The FT1 Pro is equipped with FIIOs 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 374g, the FT1 Pro packs a capable 95x86mm driver with specs rivaling 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 40kHz.

1m thin diaphragm
The difference between even a 2m and a 1m diaphragm thickness results in noticeable performance differences when the diaphragm is vibrating at high speeds, which ultimately affects sound quality

We have created for the FT1 Pro a class-leading 1m ultra-thin diaphragm, using high-performance PET as the substrate, which 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.

Sapphire Aluminum dual-coating patented technology
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.

The first coating layer is made of aluminum. Lightweight and conducive, the aluminum coating enhances the traces conductivity, helping to reduce the drivers 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 diaphragms rigidity and enhances treble resolution and overall transparency, and helps the driver to exhibit a unique sound as a bonus.

374g light weight
While the FT1 Pro features a large, double-sided magnet planar driver, it only weighs about 374g making it light, comfortable, and easy to carry around.

20 high-sensitivity design
The lightweight FT1 Pro aims to bring great planar sound without requiring serious amplification. The low 20 impedance combined with the high sensitivity of 112dB/Vrms@1kHz (or 95dB/mW@1kHz) means you can easily get great sound from the FT1 Pro.
