Lightweight planar headphones

The JT7 brings large-format planar technology into a lightweight, foldable frame that fits easily into daily listening. A 95x86mm proprietary driver, a 3µm diaphragm, a magnetic array designed for high sensitivity, and an ergonomic, serviceable build give you a headphone that delivers planar precision without the usual bulk. It’s straightforward to drive, tuned for clarity and energy, and ready for long stretches of focused listening. 

Large 95x86mm planar driver

The driver is developed entirely in-house, from diaphragm research to the magnetic circuit. This level of control matters. The wide diaphragm area works with uniform electromagnetic force across its surface, reducing sectional distortion and giving the headphone a confident sense of scale. You hear a broader stage, firmer bass, and clean transients that stay stable even at higher volumes. 

3µm ultra-thin diaphragm

A thinner diaphragm reacts faster to changes in the electrical signal. At just 3µm, the JT7’s film moves with minimal inertia, tracking subtle high-frequency details with ease. Treble takes on a crisp, effortless character, and rapid shifts in dynamics feel immediate rather than blurred. 

F.E.S. elastic system

The diaphragm surface includes multi-dimensional texturing that increases elasticity. This added compliance gives the driver more freedom to move while maintaining control of internal stress. Bass gains depth and weight without turning sluggish, and low-level information remains intact even during heavier passages. 

Precision 28nm manufacturing

The JT7 uses a chip-grade fabrication process that integrates the voice coil and diaphragm into a seamless structure. Extremely fine coil traces improve consistency and durability, while the unified construction minimizes mechanical losses. You get stable performance over time, not just on day one.

Two-way high-density magnets

Neodymium iron boron magnets arranged in a two-way layout create a strong magnetic field that drives the diaphragm efficiently. With a sensitivity of 92dB/mW, the JT7 reaches confident listening levels from a wide range of sources. Its output remains full and composed even when paired with compact devices.

Lightweight foldable frame

At about 318g, the JT7 is lighter than many planar headphones, making long listening more comfortable. Its foldable joints rotate smoothly, allowing you to store or travel with it without rearranging your space. The headphone becomes an easy companion rather than something you plan around.

Ergonomic four-axis headband

The headband’s multi-axis movement helps the pads settle naturally around your ears. This alignment improves seal, reduces pressure points, and keeps the planar driver positioned correctly. Sound delivery stays consistent even as you shift in your chair. 

Replaceable pads and cushion

The contact surfaces use a breathable mesh that stays comfortable during extended sessions. Both the earpads and headband cushion detach for cleaning or replacement, extending the life of the headphone and letting you tailor wear comfort over time. 

Detachable cable system

Dual 3.5mm connectors give you flexibility with cables. The JT7 includes a 3.5mm single-ended cable, a 4.4mm balanced cable, and a 6.3mm adapter, making it simple to match the headphone to various amplifiers and portable players. Each connection maintains a stable signal path with minimal resistance.

Hi-Res Audio certification

Certification confirms that the headphone meets industry standards for extended frequency response and low distortion. It supports wide-band playback up to 40kHz, allowing high-quality recordings to retain their nuance.
