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 for 30 seconds. If you move 

back in range after 30 seconds pass, you can manually reconnect by 
pressing the call control button.

Audio quality is also dependent upon the device with which the 

headset is paired.
