FiiO FT1 Pro Open-back Planar Headphones

FIIO-developed core, PRO sound 95x86mm FIIO-developed planar driver
The FP3 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 shelf-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, FT1 Pro features a large, almost limitless soundstage rarely found among its peers. It also effortlessly produces sound up to 40kHz.

FT1 Pro is equipped with FIIO's new patented acoustic technology - the uniform magnetic field design, which optimizes 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.

FIIO FT1 Pro is capable of wide frequency response range from 7Hz-40kHz, allowing you to truly experience even the subtlest of nuanced sounds the planar driver is capable of producing.
