Enjoy crystal-clear sound and voice quality with this wireless headset.

Convenient controls directly on the headset allow you to quickly answer and end calls, and mute and un-mute the mic without having to reach for your phone. Advanced battery provides up to eight hours of talk time and recharges completely in less than three hours. Plus, Eco-DECT means lower power requirements and fewer emissions. Softphone headset is compatible with PC and Mac computers and laptops.
