This headset is a more than a standard headset. The Voyager Focus has some advanced stuff build in. When you take of your headset while playing music, the music pauses. When you are in a Skype for Business meeting and you turn your microphone up or take of your headset it will mute you. This is all work of the Smart Sensors Plantronics has built in. The Active Noise Cancelling of this headset is working as you may expect.
