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 environ-
mental 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 repeatedly 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:

2. 

Simultaneously press the 3-way multi-function button and the power button 
for 3 seconds.
