he ATH-WS660BT wireless over-ear headphones combine exclusive 53 mm Deep Motion Drivers with Bluetooth technology to produce clear, full-range wireless audio with invigorating bass. 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.
