FiiO has introduced the FiiO JT7, a full-size headphone with planar magnetic drivers measuring 95 x 86 mm, combined with FiiO's proprietary F.E.S (FiiO Elastic System) technology and a powerful magnetic system.

The FiiO JT7 uses 3-micron-mm-thick driver diaphragms, which boast exceptional speed and a flat frequency response from 7 Hz to 40,000 Hz. FiiO's proprietary Elastic System technology creates a multidimensional surface texture on the diaphragm, increasing the driver's elasticity and allowing it to move faster.

FiiO's advanced manufacturing technology, with standards down to 28 nm, ensures seamless integration between the diaphragm and voice coil, enhancing the driver's structural integrity and durability. The model features a custom-designed magnetic architecture: a dual-sided heterogeneous system of high-power neodymium magnets that generates a magnetic field around a planar driver. This approach ensures high efficiency and sensitivity.
The FiiO JT7 headphones weigh only 318 grams, and the four-axis adjustable headband naturally adapts to various head shapes, ensuring a comfortable fit for most users. The open acoustic design creates the feeling of a large, spacious stage.
The FiiO JT7 full-size planar headphones are available now for a suggested retail price of $109.99.
