ATH-WS990BT

Solid Bass® Wireless Over-Ear Headphones with Built-in Mic & Control

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.

In addition to providing high-fidelity wireless audio, the ATH-WS990BT headphones also feature noise-cancelling and hear-through functionality that gives you greater control over your interaction with the outside world and its noise. The headphones’ selectable active noise-cancellation function dampens the ambient noise for greater enjoyment of the Solid Bass audio in loud environments. Conversely, the selectable hear-through function allows voices in the surrounding area to be heard through the headphones. This lets you listen for important announcements, say in a train station or airport, and hear the voice of anyone who might engage you in conversation.

A mic and controls are built into the left earcup, giving you convenient control of calls and music playback on a wirelessly connected device. An audio cable is also included to let you use the headphones in areas where wireless operation is prohibited (e.g., in airplanes or hospitals), when battery power is low, or when you want to listen to Hi-Res Audio.

The headphones’ internal lithium polymer battery provides up to 30 hours of continuous wireless use (up to 1,000 hours in standby mode) and can be recharged using the included 30 cm (1.0') USB charging cable.
