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. 2 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 (> 7). Once the headphones are fully charged, the LED flashes blue for 5 minutes and then goes off. 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 compatible standard USB power supply for charging the headphones.
• While the headphones are being charged, you can still listen to music or make phone calls. In this case, however, the charging time may be longer.

Charging the headphones' rechargeable  battery

1. Connect the USB-C connector of the charging cable to the USB 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 US B power source is connected to the power supply system.
   The charging process of the headphones begins. The LED displays the charge status:

• If the LED does not light up immediately during charging, clean the charging socket and charge the headphones until the LED lights up again (> 11)
• You can speed up the charging process by charging the headphones when they are switched off. 

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 the 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 immediately 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. Audio playback is only possible from one device at a time.
• If you pair the headphones 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 headphones again.
