Connecting the earphones to a Bluetooth
device
To be able to use the Bluetooth wireless connection, you must regis-
ter both devices (earphones and e.g. smartphone) via the device set-
tings of your smartphone. This process is called pairing.
If operation differs from the steps mentioned, also refer to the inst-
ruction manual of the Bluetooth device you are using.
If you switch the earphones on for the first time after initial
charging, they automatically go into 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).
Paired devices establish the Bluetooth wireless connection immedi-
ately 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.

Questions and answers
Momentum True Wireless earbuds. Left side doesn't connect. Right side seems fine. App shows both sides fully charged. When I tried a factory reset, the app said to connect the left side first, but I can't do that.
If your left earbud of the Sennheiser MOMENTUM True Wireless is not connecting, try these steps:
1. Restart Bluetooth – Turn off Bluetooth on your phone for a few seconds, then turn it back on.
2. Reset the Earbuds – Place both earbuds in the charging case, close the lid for a few seconds, then open it.
3. Re-enter Pairing Mode – Remove both earbuds from the case, then press and hold both touch controls until the right earbud blinks blue and red, indicating pairing mode.
4. Reconnect to Your Device – Try pairing the earbuds again with your smartphone via Bluetooth.
If the issue persists, ensure the earbuds and charging case are charged by connecting them to a USB power source.
