Range
To maintain a connection, keep your headset within 33 feet (10 meters) of the Bluetooth device. If there are obstacles between your headset and the device you may experience interference. For optimal performance, place your headset and phone on the same side of your body.
As you move out of range, audio quality degrades. When you are far enough away to lose the connection, you hear a high tone in the headset. The headset attempts to reconnect after 30 seconds. If you move back in range later, you can manually reconnect by pressing the call control button.
NOTE: Audio quality is also dependent upon the device with which the headset is paired.
