Наушники — FiiO FT7

The FT7 is an open-back planar magnetic headphone from FiiO, the Chinese audio company founded in 2007 by former OPPO Digital senior engineers, marking FiiO's first genuine entry into the flagship headphone world. Priced at $699 after two years of dedicated development and a full year of continuous playback testing before launch, the FT7 uses FiiO's own self-developed 106mm planar driver - among the largest planar drivers currently used in any full-size headphone.

Key specs that matter

The diaphragm is an extraordinarily thin 1-micron PET substrate with vacuum-deposited, laser-patterned gold and silver traces in a patented multi-layer coating - gold's high density and internal resistance enhances diaphragm damping for relaxed, enjoyable mid and low frequencies, while silver's low resistance and high conductivity carries high-frequency signals with minimal loss for detailed treble. A dual-sided push-pull magnetic circuit uses 18 high-performance N52 neodymium magnets per driver (9 per side) with magnetic flux up to 1.5 Tesla, arranged with rounded-corner geometry specifically to create a uniform magnetic field across the entire diaphragm surface - this evenness reduces driver breakup and distortion that uneven magnetic stress would otherwise cause, while also helping keep driver weight down. Impedance is 25 ohms with 94dB/mW sensitivity, frequency response spanning 5Hz to 40kHz, and clamping force measured at 4.2N (±0.3N) - easy to drive compared with many dual-sided planar designs of similar size, though it still scales meaningfully with more capable sources. Weight is just 427g despite the large 106mm driver, achieved through extensive use of lightweight, high-strength carbon fiber in both headband and housing construction - exceptional for a high-end planar headphone. Real Zebrawood grilles, sourced from West African trees typically grown at 1,600 metres altitude, frame the drivers. A 3-metre cable made from cryogenically treated 6N OCC (99.99998% pure) monocrystalline copper, frozen at -192°C for 7 days to relieve internal metal stress and tighten crystal boundaries, terminates in a 4.4mm balanced connector with included 6.35mm single-ended and 4-pin XLR adapters. Two interchangeable earpad sets - lambskin and breathable fabric - use a directional locking mechanism for easy swapping.

Sound and use context

Expect crisp detail, precise spatial imaging and a wide, open soundstage showing off the best of planar characteristics - full-bodied, detailed bass with strong kick-drum presence, tight rather than loose low-end control, and a forward, expressive male-vocal presentation comparable to headphones like the Focal Stellia and MM-500.

Pairing

The 25 ohm impedance and 94dB sensitivity mean the FT7 gets loud even from portable DACs and DAPs, though it rewards a more capable amplifier with greater dynamic scaling, and the lambskin pads specifically deliver clearer sound with wider staging and enhanced detail retrieval compared with the alternative fabric pads.

Alternatives

FiiO's own FT1 Pro sits below this flagship as a more accessible open-back planar alternative sharing similar high-sensitivity design goals, worth considering instead if the FT7's flagship price and considerable accessory set exceed what a specific budget requires for a first step into planar headphones.
