The ATH-WS990BT wireless over-ear headphones combine exclusive 53 mm Deep Motion Drivers with large, high-flux magnetic circuitry and Bluetooth technology to deliver vibrant full-range wireless audio with invigorating bass. The powerful magnetic force of the circuitry results in dynamic, well-tailored diaphragm response to reproduce deep, clear low frequencies and detailed mid-to-high frequencies. The sound is further enhanced by the exclusive dual-layer, memory-foam earpads, comprised of a firm internal layer and a soft outer layer, that provide excellent sound isolation and comfort. The headphones can even reproduce Hi-Res Audio when used with the included 1.2 m (3. 9') audio cable.
