Its 800 nm diaphragm is 86.7% thinner than the previous generation and carries a full-surface diamond coating, so it stays rigid without gaining mass and keeps its response clean out to 40 kHz. North American FAS-grade black walnut earcups and a carbon fibre headband hold the weight to 425 g. A flagship planar with an easy-drive character, available at Soundium.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e101 mm planar driver:\u003c\/strong\u003e 6,443.5 mm² of effective radiating area for a wide, open stage.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e800 nm diamond-coated diaphragm:\u003c\/strong\u003e 86.7% thinner than the previous generation, with a full-surface diamond coating applied by vapour deposition to reduce high-frequency breakup.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePatented uniform magnetic field:\u003c\/strong\u003e Custom contoured high-strength magnets drive the diaphragm evenly and cut vibrational distortion at the source.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e28 nm electroplated voice coil:\u003c\/strong\u003e Chip-grade process with a silver-aluminium alloy coating for a structurally stable coil.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEasy to drive:\u003c\/strong\u003e 95 dB\/mW sensitivity and 24 Ω impedance, so a USB dongle can carry it.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e425 g with carbon fibre headband:\u003c\/strong\u003e Light for a full-size planar, with pressure spread for long sessions.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlack walnut earcups:\u003c\/strong\u003e North American FAS-grade walnut, so every pair has its own grain.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCryo-treated 6N copper cable:\u003c\/strong\u003e 99.99998% monocrystalline copper, treated 100+ hours at −192 °C, terminated in 4.4 mm balanced.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTwo sets of earpads:\u003c\/strong\u003e Suede pads fitted from the box for warmth and bass weight, protein leather pads for extra treble resolution.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHi-Res Audio certified:\u003c\/strong\u003e Certified by the Japan Audio Society.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCustomer Benefits\u003c\/h4\u003e\n\u003cp\u003eBig planars usually demand a big amplifier. The FT15 does not: 24 Ω and 95 dB\/mW mean a dongle or a modest desktop amp already gets it to volume, and the 101 mm driver still gives you the scale you buy a full-size planar for. The two pad sets let you tune the balance yourself, the 4.4 mm balanced cable ships with 6.35 mm and XLR-4 adapters so it fits whatever output you already own, and 425 g on a carbon fibre headband keeps a long evening comfortable.\u003c\/p\u003e\n\u003ch4\u003eQuick Specs\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Full-size open-back planar magnetic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDriver:\u003c\/strong\u003e 101 mm proprietary planar, 6,443.5 mm² radiating area\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 7 Hz to 40 kHz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eImpedance:\u003c\/strong\u003e 24 Ω at 1 kHz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSensitivity:\u003c\/strong\u003e 95 dB\/mW (111 dB\/Vrms) at 1 kHz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 425 g without cable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClamping force:\u003c\/strong\u003e 3.8 N ±0.3 N\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCable:\u003c\/strong\u003e 1.5 m, 6N monocrystalline copper, dual 3.5 mm TS to 4.4 mm balanced\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eWhat's in the Box\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFT15 headphones\u003c\/li\u003e\n  \u003cli\u003e4.4 mm balanced headphone cable\u003c\/li\u003e\n  \u003cli\u003eXLR-4 (male) to 4.4 mm (female) balanced adapter\u003c\/li\u003e\n  \u003cli\u003e4.4 mm (female) to 6.35 mm (male) adapter\u003c\/li\u003e\n  \u003cli\u003eSuede earpads (pre-installed)\u003c\/li\u003e\n  \u003cli\u003eProtein leather earpads\u003c\/li\u003e\n  \u003cli\u003eFabric storage case\u003c\/li\u003e\n  \u003cli\u003eQuick start guide\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eIdeal For\u003c\/h4\u003e\n\u003cp\u003eHome listening on a desktop or valve amp, balanced 4.4 mm sources, and listeners who want flagship planar scale without a power-hungry load.\u003c\/p\u003e\n\u003ch4\u003ePros \u0026amp; Cons\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003e✅ Pros:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e101 mm driver with an 800 nm diamond-coated diaphragm\u003c\/li\u003e\n  \u003cli\u003e24 Ω and 95 dB\/mW, so it runs from a dongle\u003c\/li\u003e\n  \u003cli\u003eTwo pad sets included for two voicings\u003c\/li\u003e\n  \u003cli\u003e4.4 mm balanced cable plus 6.35 mm and XLR-4 adapters\u003c\/li\u003e\n  \u003cli\u003eWalnut and carbon fibre build at 425 g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e⚠ Cons:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eOpen-back design leaks sound both ways, so it is a room headphone, not an office or commuting one\u003c\/li\u003e\n  \u003cli\u003eNo 3.5 mm single-ended cable in the box, so a 3.5 mm source needs an adapter you supply\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIf you want the scale of a 101 mm planar without building an amplifier chain around it, the FT15 is the easiest flagship in its class to live with.
