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. 3 hours. The headphones provide 1.5
hours of playback time with a charging time of approx. 10 minutes.
Before using the headphones for the first time, charge the recharge
-
able battery for a complete charging cycle without interruption.
When the headphones are being charged, the LED lights up (> 7).
When the battery charge drops to a critical level, a voice prompt asks
you to recharge the headphones (“Recharge headset”).
Sennheiser recommends to charge the headphones using the sup-
plied USB-C cable and a compatible standard USB-C power supply
unit.
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 USB cable to the USB-C
socket of the headphones.
