Fiio JT7 Open-Back Planar Headphones

The FiiO JT7, from FiiO's value-focused JadeAudio line, brings genuine large-format planar magnetic sound to a price where most headphones still use basic dynamic drivers. Even better, it folds, weighs just 318g, and ships with both single-ended and balanced cables.

Type and Technology

The JT7 is an open-back over-ear planar with a 95x86mm driver and a 3 micron PET diaphragm carrying a silver-plated aluminum alloy voice coil. FiiO's Elastic System embosses folds into the diaphragm for greater flexibility and excursion, while neodymium iron boron magnets in a two-way layout create a strong, efficient field. At 18 ohms and 92dB/mW, it reaches confident volumes even from compact devices.

Sound Character

Expect the planar signature: quick, tight bass, smooth and even mids, and airy, well-extended treble with none of the one-note boom of cheap dynamics. The open back opens up the stage so music feels spacious and uncongested, ideal for long, focused listening sessions.

Build and Comfort

Thoroughly unlike typical heavyweight planars, the JT7 tips the scales at 318g and its user-friendly foldable design swivels flat and compact for a drawer, a bag, or a desk hook. Cables detach at dual 3.5mm connectors, and both 3.5mm and 4.4mm balanced cables plus a 6.3mm adapter are included.

Best For

First-time planar buyers, desk setups, and anyone who wants open-back sound that stores away easily. It pairs nicely with a portable DAC amp such as the FiiO BTR7. Browse our headphones collection and the full FiiO lineup for more.
