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 you, and therefore the headphones, leave the Bluetooth transmis-
sion range of the smartphone, the sound quality deteriorates
increasingly until you hear the voice prompt “Lost connection” and
the connection breaks down completely. If you immediately re-enter
the Bluetooth transmission range, the connection is automatically
re-established.
