FiiO JadeAudio JT9 Open-Back Planar Magnetic Headphones
The FiiO JadeAudio JT9 is a foldable open-back planar magnetic headphone built around a large proprietary 3.74 x 3.39 in (95 x 86 mm) planar driver. Its ultra-thin 0.000039 in (1 μm) diaphragm, sapphire and aluminum dual-coating technology and uniform magnetic field design are engineered to deliver fast transient response, fine detail and a spacious presentation.
The planar diaphragm combines a lightweight aluminum conductive layer with a rigid sapphire coating on a high-performance PET substrate. FiiO's optimized magnetic circuit distributes magnetic force evenly across the driver, helping maintain controlled diaphragm movement while reducing unwanted break-up and distortion.
With a 20-ohm impedance and sensitivity of 95dB/mW at 1kHz, the JT9 is designed to be easier to drive than many conventional planar magnetic headphones. FiiO recommends 300mW or more of amplifier output to fully drive the headphones.
The JT9 weighs approximately 12.9 oz (365 g) without its cable and features rotating, folding ear cups and a multi-axis headband for a comfortable, adaptable fit. Separate 3.5 mm single-ended and 4.4 mm balanced cables are included, along with a fitted water-resistant storage case.
