Connecting the earphones to a Bluetooth device
To be able to use the Bluetooth wireless connection, you must register both devices (earphones 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 the earphones on for the first time after initial charging, they automatically switch to pairing mode.
Information on the Bluetooth wireless connection
The earphones 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).
MOMENTUM True Wireless | 13
Using the earphones
Paired devices establish the Bluetooth wireless connection immediately after switch-on and are ready for use.
When you switch the earphones on, they automatically try to connect to the last connected Bluetooth device. The earphones can save the connection profiles of up to eight Bluetooth devices with which they have been paired.
If you pair the earphones with the ninth Bluetooth device, the saved connection profile of the least used Bluetooth device will be overwritten. If you want to re-establish a connection with the overwritten
Bluetooth device, you have to pair the earphones again.

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 earphones, leave the Bluetooth transmission 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 of the smartphone, the connection is automatically re-established and you hear the voice prompt “Connected”. If this is not the case, tap the touch control panel of the earbud once.
The right earbud (primary earbud) can be used alone. The left earbud
(secondary earbud) cannot be used alone because it requires the right earbud for Bluetooth transmission.
Restarting the earphones
If the function of the earphones is disturbed, perform a restart:
▷ Make sure that the contacts on the earbuds and in the charging case are clean and make contact (the LED of the charging case lights up when you insert the earbuds into the charging case). If
necessary, clean the contacts (> 25).
▷ Use the USB cable to connect the charging case to a power
▷
Insert the earbuds into the charging case and, within 60 seconds, touch and hold the right and the left touch control panel for 6 seconds.
The earphones are restarted.
