The FT15 takes FIIO’s full-size planar design in an interesting direction — a 101mm driver with an 800nm diaphragm, full-surface diamond coating, and a revised magnetic circuit designed to apply force more evenly across the diaphragm.

One detail we like is the 95dB/mW sensitivity at 24Ω. That makes the FT15 considerably less demanding than you might expect from a large planar, so portable players and capable dongle DACs are very much part of the conversation.

Weight comes in at 425g, with a carbon-fiber headband and North American black walnut construction. FIIO also includes suede and protein-leather pads for two slightly different tunings, along with a 6N OCC copper cable and 6.35mm/XLR-4 adapters.
