FiiO FT5, Open-Back Headphones: 90mm Drivers with 4.4, 3.5, and XLR Jack Planar Magnetic Headphone (FT 5)

90mm Open Planar Magnetic Headphones FT5 Is Officially Released!

Discover micron-level manufacturing and technology

The all-new FT5 is FIIO’s first planar magnetic headphones. Planar magnetic drivers are in between dynamic and electrostatic headphones. Like dynamic headphones, there is a sort of coil on the planar driver. Similar to electrostatic headphones, the diaphragm is a special kind of thin, micron-level film. The FT5 is 28nm chip-scale processed, leading to an approximately 6μm thick diaphragm. These characteristics of the planar driver make it possible to create a headphone that is not only highly detailed, but also easy to power.

Large 90mm planar magnetic driver

The FIIO FT5 employs an outstanding large 90mm planar magnetic driver. Compared to a traditional dynamic driver, a planar magnetic driver converts sound energy to sound waves in a more balanced way, by vibrating in a much more even way. The vibrations are distributed across the entire driver diaphragm and there is little distortion caused by the rigidity of the diaphragm material. Thus, the FIIO FT5 can truly and accurately express audio signals

Micron-plated aluminum-silver alloy coils

During the development of the FT5, the R&D engineers not only needed to consider how the coils would interact with the 6μm thin diaphragm, but also the density and conductivity of the coils themselves. Having examined and tested various commonly-used materials* to plate planar coils, FIIO engineers determined that the lighter aluminum alloy material was best for the coils. Also, they determined that mixing in silver metal would also enhance conductivity of the coils, making the driver easier to power without sacrificing the high-frequency detail and rich sound characteristic of good planar magnetic drivers.

High sensitivity and easy to power

The FT5’s driver is both light and strong, allowing for a high sensitivity of 110dB/1Vrms@1kHz i.e. 96dB/mW@1kHz. This allows the FT5 to be easily driven even by portable players.

392 wires of high-purity silver-plated monocrystalline copper cable

The FT5 comes with a 1.5m cable made of 392 wires of silver-plated monocrystalline copper, each wire with a diameter of 23AWG. The copper wires help to give a solid and highly-detailed sound, fully transmitting lossless sound directly to you.
