Dell Premier Wireless ANC Headset – WL7022 is engineered with: an immersive audio experience with high quality stereo sound. An on-demand active noise cancellation (ANC) switch allows you to toggle between blocking out ambient sounds or staying connected with your surroundings. Carefully tuned triple-mics offer superior background noise canceling, picking up only your voice, not the surrounding noise. A dedicated mute button on your boom mic offers quick access to mute and unmute. It doubles up as an open mic button, providing you the choice to listen to the surrounding sounds when you are not on a call. Color and behavior of the status indicator light on your USB dongle keep you informed of your call status across devices like laptops, tablets and smartphones wherever you go. Adjustable leatherette headband and earpads offer a comfortable and secure fit, keeping you productive all day. Wear your boom mic on either side based on your preference. A hearing protection feature detects sudden loud sounds and protects your ears by preventing audio spikes. Easily charge your headset by placing it on the charging stand or via the micro-USB port. Foldable earpads let you easily pack up and an included pouch protects your headset on the go.
