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 earbuds, leave the Bluetooth transmission
range of the smartphone, the sound quality deteriorates increasingly
until and the connection breaks down completely. If you immediately
re-enter the Bluetooth transmission range, the connection is auto-
matically re-established. If the connection is not automatically re-
established, insert the earbuds briefly into the charging case before
switching them on again.
