The FiiO FT5 consists of open-back planar magnetic headphones that feature a large 90mm driver designed for immersive audio experiences. With an ultra-thin diaphragm measuring 6um, this model emphasizes both sound fidelity and durability. It is built using a lightweight magnesium aluminum alloy, allowing for comfort during extended use. The headphones are equipped with a dual N52 Neodymium magnet array consisting of 20 magnets per driver, which enhances sound clarity and reduces distortion. Priced at $499, the FT5 is positioned within the competitive market against similar offerings, and it boasts a sensitivity of 110dB/Vrms at 1kHz, making it relatively easy to drive even with portable sources. It comes with interchangeable connectors (3.5mm, 4.4mm, and other adapters), and users are provided with two sets of earpads made from suede and protein leather. The FT5's design aims to deliver a U-shaped sound signature that features pronounced bass and clear treble, providing an enjoyable listening experience across a variety of genres without losing detail. Its sound reproduction is characterized by a rich bass response, smooth mids, and a well-controlled treble that is free from excessive sibilance. With notable build quality and extensive accessories included, the FT5 stands out as a strong contender for those entering the planar magnetic headphone space.
