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.
