FiiO FT5 90mm Open Back Planar Magnetic Headphones
A sonic revolution in headphone technology
Welcome to the FiiO FT5 90mm Open Back Planar Magnetic Headphones, a breakthrough in personal audio that combines cutting-edge technology with unparalleled comfort. FiiO's first set of planar magnetic headphones, they feature large 90mm drivers, a feather-like 6um ultra-thin diaphragm, and high-end micron-plated aluminum-silver alloy coils.
Ride the lightning: Planar magnetic drivers
Planar magnetic technology brings together the best of dynamic and electrostatic headphones, offering rich detail and incredible power. The FT5 leverages a large 90mm planar magnetic driver, utilizing 20 neodymium magnets per driver to give your audio a life-like quality rarely found in headphones.
Whisper-thin yet durable: 6um ultra-thin diaphragm
Balancing sound quality and reliability can be a tricky feat. But FiiO nailed it with a 6um ultra-thin diaphragm that is both resilient and capable of producing high fidelity sound. Tested extensively to find the ideal thickness and material, this diaphragm proves that bigger isn't always better.
Micron-plated aluminum-silver alloy coils
The FT5's design emphasizes meticulous attention to detail, particularly in its coil construction. FiiO’s selection process for materials involved comprehensive testing, leading to the choice of a lightweight aluminum alloy intermingled with silver. This composition was chosen for its ability to improve conductivity. Such precise material engineering aims to deliver an auditory experience that not only satisfies but surpasses the standards of audio enthusiasts.
Magnet harmony: 20 neodymium magnets per driver
By carefully balancing 11 magnets inside and 9 outside the driver, the FT5 achieves a harmonious magnetic field. This optimized setup leads to a consistent driver movement and significantly reduced distortion, offering you a higher fidelity sound experience.
Power without the bulk: High sensitivity and easy to drive
Gone are the days of lugging around bulky equipment just to get the most out of your headphones. With a high sensitivity of 110dB/1 Vrms@1kHz, the FT5 can be powered effortlessly by portable players. Now you can take that concert hall quality sound with you, wherever you go.
Supreme comfort: Lightweight magnesium aluminum alloy construction
The FT5’s body is made of a lightweight magnesium aluminum alloy, giving you the comfort needed for extended listening sessions. The material is 64% as dense as traditional aluminum alloy, ensuring that the headphones stay comfortable, even during long listening stretches.
Wide-open spaces: Open-backed design
If you're looking for headphones that provide a vast soundstage and treble resolution, the open-back design of the FT5 has you covered. The carefully engineered structure ensures that you’re immersed in your music.
Interchangeability at its finest: 4 types of audio plugs
