Smart Sensors enable you to:
Answer a call simply by putting on your headset.
Pause streaming media by removing the headset, and resume your media by putting your headset back on.
Transfer call audio back and forth between the phone and headset. To do so, if you are not wearing your headset and you receive a call on your mobile phone, the audio routes to the phone. Put on the headset to transfer the audio to the headset. If you are already wearing your headset and there is an incoming call, the audio will be routed to the headset. Take off the headset to transfer the audio to the phone.
