FiiO JT3 black

FiiO JT3 black
The FiiO JT3 are open-back, over-ear headphones with 50mm dynamic drivers, designed for a spatial and detailed listening experience. The open-back design supports natural sound propagation, a wide soundstage, and precise spatial rendering, while the drivers with a PEK+PU composite diaphragm use powerful N52 magnets. A detachable oxygen-free copper cable with palladium plating includes a microphone and controls for both calls and gaming. The construction is complemented by removable and washable velvet earpads with memory foam, a stainless steel and zinc alloy headband, and perforated aluminium-magnesium alloy grilles.

50mm dynamic drivers with an open-back design
The FiiO JT3 use 50mm dynamic drivers with a composite polymer diaphragm made of PEK and PU materials. The rigidity of PEK is combined with the flexibility of PU, and a brass damping ring helps to reduce distortion and unwanted diaphragm resonance. A lightweight TIL former and CCAW voice coil contribute to higher driver sensitivity and the ability to reproduce fine audio details. Powerful N52 magnets support fast response and driver dynamics. The open-back design limits the build-up of pressure and standing waves inside the earcups, contributing to a wide soundstage and accurate spatial imaging.
Comfortable design and detachable cable
The drivers are angled to better match the shape of the human ear while optimising airflow inside the earcups. The velvet earpads with an inner layer of memory foam can be removed and washed, making them easy to maintain. The headband uses stainless steel and a zinc alloy, while the perforated outer grilles are made from a lightweight aluminium-magnesium alloy. The detachable cable is made from palladium-plated oxygen-free copper, uses two interchangeable 3.5mm TRS connectors on the headphone side, and comes with a 6.3mm jack adapter. The cable also includes a microphone and controls that can be used for calls or gaming.
