FiiO FT5 Black On-ear Headphones

Planar magnetic drivers lie between dynamic and electrostatic headphones in terms of sound. As with dynamic headphones, there is a kind of coil on the planar driver. Similar to electrostatic headphones, the diaphragm is a special type of thin foil in the micrometer range. These properties of the planar driver make it possible to develop headphones that not only sound very detailed, but can also be easily powered. The FT5 is the first planar magnetic headphone from FIIO that gives your sound the energy of a thunderstorm.
The FIIO FT5 has an outstanding large 90 mm planar magnet driver. Compared to a conventional dynamic driver, a planar magnet driver converts sound energy into sound waves in a more balanced way by vibrating much more evenly. The vibrations are distributed over the entire diaphragm of the driver and there is hardly any distortion caused by the stiffness of the diaphragm material. This allows the FIIO FT5 to reproduce audio signals truthfully and accurately, faithfully reproducing every single note and giving you lossless hi-fi sound.
When designing the FiiO FT5, the development team didn't just blindly chase bigger (or smaller) numbers - rather, everything was designed to meet stringent sound performance targets. FiiO realized that a diaphragm that is too thin can easily cause the coils attached to the diaphragm to fall off, leaving the user with unusable headphones. Therefore, after extensive testing, the FiiO development team determined that a thickness of 6μm was the ideal balance between sound performance and reliability. For the diaphragm itself, the FiiO development team investigated various materials such as PET, PEI and PAR. After extensive sound quality and reliability testing, the development team chose PAR thanks to its superior performance on the above criteria compared to other materials. The PAR diaphragm is not only the backbone of the FT5's excellent dynamics and highly detailed sound, but also of the rich bass not normally found in headphones with planar magnet technology.
