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 “No connection” and the
connection breaks down completely. If you immediately re-enter the
Bluetooth transmission range, the connection is automatically re-
established and you hear the voice prompt “Connected”. If this is not
the case, press the multi-function button of the headphones once.
