Leaving The Bluetooth Transmission Range; Clearing Previously Paired Devices - Sennheiser HD 4.40BT Guía Rápida

Troubleshooting

Leaving the Bluetooth transmission range

Wireless calling and streaming are only possible in the Bluetooth transmission
range of your smartphone. The transmission range largely depends on
environmental conditions such as wall thickness, wall composition etc. With a
free line of sight, the transmission range of most smartphones and Bluetooth
devices is up to 10 meters.
If the headphones leave the Bluetooth transmission range of the smartphone,
the sound quality deteriorates and you hear the voice prompt "lost connection".
At this point, the connection breaks down completely. You can re-establish the
connection if you re-enter the Bluetooth transmission range and you hear the
voice prompt "connected".
To re-establish the connection, press the multifunction button.
