Using the headphones
Information on the rechargeable battery
and the charging process
The headphones have a built-in rechargeable battery. A complete
charging cycle takes approx. 1.5 hours. Before using the headphones
for the first time, charge the rechargeable battery for a complete
charging cycle without interruption.
When the headphones are being charged, the LED lights up (>6).
When the battery charge drops to a critical level, a voice prompt asks
you to recharge the headphones (“Recharge headset”).
Sennheiser recommends using the supplied USB cable and a com-
patible standard USB power supply for charging the headphones.
Charging the headphones' rechargeable
battery
1. Connect the USB-C connector of the USB cable to the USB-C socket
of the headphones.
2. Connect the USB-A 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 displays

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.
Information on the Bluetooth wireless
connection
The headphones are compatible with Bluetooth 5.0.
If your audio source supports AAC audio encoding, music is auto-
matically played in high audio quality: 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.
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.
If you switch on the headphones for the first time, they auto-
matically switch to pairing mode.
