Connecting the headphones to a
Bluetooth device
To be able to use the Bluetooth wireless connection, you must regis-
ter both devices (headphones and e.g. smartphone) via the device
settings of your smartphone. 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.
If you switch on the headphones for the first time, they auto-
matically 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, aptX HD, LHDC or AAC. Otherwise the head-
phones 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
connection profiles of up to eight Bluetooth devices with which they
have been paired.
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.
