Description
Audiophiles seeking a full-sized open-back planar magnetic headphone with exceptional technical performance will find the FiiO FT7 a compelling flagship. At its heart sits a self-developed 106mm planar driver featuring FiiO's patented multi-layer gold and silver coating on an ultra-thin 1μm PET diaphragm — a process borrowed from semiconductor thin-film manufacturing. The result is a transducer that delivers a wide, open presentation with precise detail retrieval and agile transient response.
Lightweight carbon fiber construction keeps the FT7 to 427 g, while the suspension headband with leather padding and deep circumaural cups distribute pressure evenly for extended listening sessions. Two sets of earpads — perforated lambskin and breathable fabric — let you shift between a neutral, analytical signature and a warmer, more intimate presentation. The included 3 m cryogenically treated 6N OCC monocrystalline copper cable with PFA insulation and dual 3.5mm connectors pairs with a 4.4mm balanced termination, while the zebrawood grille adds a distinctive natural accent. Headfonia reviewers describe the FT7 as "one of the best open-back planar headphones you can buy for under $1,000," praising its build, comfort, and accessory completeness.
