2. Connect the other USB-C connector to a corresponding socket of
a USB power source (* to be ordered separately). Make sure that
the USB power source is connected to the power supply system.
The charging process of the headphones begins. The LED dis-

If you do not have a USB power source with a USB-C socket,
use the USB adapter (supplied) for connection to a USB-A
socket.
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 your Bluetooth device supports auto pairing via NFC (Near Field
Communication), the connection is automatically established.
If your Bluetooth device does not support NFC, use the device set-
tings for the pairing process.
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
connection profiles of up to eight Bluetooth devices with which they
have been paired.
