A 3µm diaphragm with FiiO’s F.E.S. elastic system, made with the same 28nm chip-grade process as the flagship FT7, gives detailed, lively sound with fuller bass than most planars. It weighs just 318g, folds for travel, and at 18Ω is easy to drive, with 3.5mm and 4.4mm balanced cables in the box. It is Hi-Res Audio certified.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-jade-audio-jt7-open-back-planar-headphones-photo-colours.jpg?v=1791316219\" alt=\"FiiO Jade Audio JT7 open-back planar headphones in champagne and black\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eWhy planar?\u003c\/h3\u003e\n\u003cp\u003eA dynamic or balanced armature driver pushes the diaphragm from one point. In a planar driver, an electromagnetic force acts across the whole of a light, thin diaphragm, so it moves evenly, virtually eliminating the break-up that dynamic drivers can suffer. The result, as FiiO puts it, is low distortion, superb transient response and a vast soundstage. Planars are complex to make, which usually makes them expensive; the JT7 brings the technology within easier reach.\u003c\/p\u003e\n\u003ch3\u003eA 95 × 86mm driver, developed in-house\u003c\/h3\u003e\n\u003cp\u003eFiiO developed the JT7’s driver from the ground up, from the diaphragm to the voice coil and magnetic circuit, which keeps the sound consistent from unit to unit. Its large size gives an expansive soundstage and powerful, energetic bass.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-jade-audio-jt7-open-back-planar-headphones-photo-diaphragm.jpg?v=1791316223\" alt=\"The FiiO JT7 planar diaphragm with its printed voice-coil trace\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003e3µm diaphragm with F.E.S.\u003c\/h3\u003e\n\u003cp\u003eA planar diaphragm has to be extremely thin to respond quickly. The JT7’s is just 3µm, so it captures tiny changes in the signal, for excellent transients and brilliantly clear treble. FiiO’s F.E.S. (FiiO Elastic System) adds multi-dimensional textures to the film, similar to the surround of a dynamic driver. They give the diaphragm an extra dimension to flex in, building elastic force that counteracts internal stress, so it can move further without added distortion: more effortless bass with greater presence.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-jade-audio-jt7-open-back-planar-headphones-photo-3.jpg?v=1791146284\" alt=\"Exploded view of the FiiO JT7 planar driver and magnets\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eChip-grade manufacturing\u003c\/h3\u003e\n\u003cp\u003eLike the FP3, FT1 Pro and FT7, the JT7’s driver is made with a 28nm chip-grade process derived from high-precision plating in the semiconductor industry.
