If the LED does not light up immediately during charging, clean
the charging socket and charge the headphones until the LED
lights up again (> 11).
You can speed up the charging process by charging the head-
phones when they are switched off.
Connecting the headphones to a
Bluetooth device
To be able to use the Bluetooth connection, you must register both
devices (headphones and e.g. smartphone) once. This process is
called pairing.
If operation differs from the steps mentioned, also refer to the
instruction manual of the Bluetooth device you are using.
When you switch on the headphones for the first time, they
automatically switch to pairing mode.
Information on the Bluetooth wireless
connection
The headphones are compatible with Bluetooth 5.0.
If your audio source supports one of the following high-resolution
audio encoding methods, music is automatically played in high audio
quality: aptX, aptX LL or AAC. Otherwise the headphones will play
your music in normal audio quality (SBC).
Paired devices establish the Bluetooth wireless connection immedi-
ately after switch-on and are ready for use.
On switch-on, the headphones automatically try to connect to the last
two connected Bluetooth devices. The headphones can save the con-
nection profiles of up to eight Bluetooth devices with which they have
been paired. Audio playback is only possible from one device at a time.
If you pair the headphones with the ninth Bluetooth device, the saved
connection profile of the least used Bluetooth device will be over-
written. If you want to re-establish a connection with the overwritten
Bluetooth device, you have to pair the headphones again.
