FiiO JT7 Planar Magnetic Open-Back Over-Ear Headphone

Proprietary driver, makes a large impact

Jade Audio has poured much effort into developing the JT7’s driver from the ground up, controlling every aspect from diaphragm R&D to the voice coil and magnetic circuit. Being totally developed in-house means guaranteed consistent, excellent sound quality. The generously sized planar driver allows you to indulge in an expansive soundstage and powerful, energetic bass.

95x86mm Planar Driver

FiiO has poured much effort into developing the JT7's driver from the ground up, controlling every aspect from diaphragm R&D to the voice coil and magnetic circuit. Being totally developed in-house means guaranteed consistent, excellent sound quality. The generously sized planar driver allows you to indulge in an expansive soundstage and powerful, energetic bass. 

Ultra-Thin Diaphragm

For a planar driver to deliver its signature quick vibration and sensitive response, it must be exceptionally thin. The JT7's diaphragm measures just 3µm, enabling it to precisely capture minute changes in the electrical signal. The result is excellent transient response performance and 

F.E.S. (FiiO Elastic System)

The JT7 features the proprietary F.E.S. design on the driver diaphragm, which incorporates multi-dimensional textures on that surface. These textures, similar to the surround ring on a dynamic driver, increase the diaphragm's elasticity. This allows for precise control over internal stress, allowing the driver to move more freely without added distortion. The result is effortless bass with a greater presence. 

Strong Magnetic Field

The JT7's 92dB/mW sensitivity is thanks to the powerful magnetic field generated by high-performance two-way neodymium iron boron magnets. These magnets deliver robust and ample driving force to the planar driver, enabling a louder and fuller sound even from weaker audio sources. 

Precision Wiring, Seamless Design

The headphones are manufactures with the same premium process as the FT1 Pro and FT7. The manufacturing process is derived from the high-precision plating used in the semiconductor industry, which enables the voice coil and diaphragm to be seamlessly integrated as one piece. This not only yields extremely fine coil wiring but also significantly boosts the coil's structural integrity. 

User-Centered Innovation

Tipping the scales at just 11oz, the JT7 is thoroughly unlike typical planar headphones that are much heavier. The user-friendly foldable design allows you to easily swivel and make the headphones more compact for easier storage and carry. 

The multi-axis ergonomic headband allows the ear pads and joints to be flexible, ensuring optimal fit that precisely contours to your ears and head. The precise fit guarantees accurate sound delivery while maximizing comfort. 

The parts of the ear pads in contact with the skin are made of comfortable, highly breathable mesh material that reduces heat and stuffiness during extended listening. Both the ear pads and headband cushion are detachable, allowing for easy cleaning and replacement.
