FiiO has officially stepped into the world of open-back headphones with the all-new JT3, a pair that blends elegant industrial design with an unmistakably high-end acoustic signature. These aren’t just another set of stylish cans — they’re crafted for serious listening, whether you’re mixing tracks in the studio or sinking into a vinyl-night session at home.
A Soundstage That Breathes
At the heart of the JT3 lies a 50mm dynamic driver, engineered to deliver a vast, three-dimensional soundstage with rich, muscular bass and sparkling treble extension. The diaphragm is made from a PEK+PU composite — PEK lending rigidity and control, while PU adds elasticity and warmth. This clever hybrid results in remarkably low distortion and natural timbre, even during complex musical passages.
A brass damping ring inside the driver further tames unwanted resonance, allowing fine microdetails to shine through — from the subtle brush of a snare to the lingering decay of a piano note.
Engineering That Delivers Emotion
The JT3 uses ultra-fine CCAW voice coils wound on a heat-resistant TIL former, paired with N52 neodymium magnets for speed, precision, and control. This combination boosts sensitivity and transient response, letting you hear every nuance exactly as intended — fast, articulate, and effortlessly musical.
The FiiO JT3 are new open-back dynamic headphones that combine sophisticated acoustic design, durable materials, and attention to detail.
Design Built for the Long Session
The open-back enclosures are crafted from a lightweight aluminum-magnesium alloy, featuring precisely machined perforations that relieve pressure and minimize reflections. The result? A natural, airy sound with pinpoint imaging and lifelike instrument placement.
FiiO even angled the drivers to align perfectly with the human ear, improving both airflow and acoustic balance, while maintaining comfort during long listening sessions.
The soft velvet ear pads with memory foam are easy to remove and clean. The material is pleasant to the touch and retains its shape with regular use.
Comfort That Feels Premium
A stainless steel and zinc alloy headband ensures structural integrity and durability, with ball-bearing adjustment guides for smooth, precise sizing. Despite the metal build, the headphones weigh only 330 grams, offering a stable yet gentle fit.
The velvet memory-foam earpads are soft, breathable, and removable for easy cleaning. They contour perfectly to your head, maintaining shape and comfort even after hours of use.
Audiophile-Grade Cable
The detachable palladium-plated, 4N oxygen-free copper cable measures 1.5 meters and uses dual 3.5mm TRS connectors. It comes with a 6.3mm adapter for studio gear and — in true FiiO fashion — includes a secondary headset cable with an inline mic and control buttons for casual listening.
