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.
Audio quality degrades as you move out of range. 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, 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.
