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 display 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 using the supplied USB cable and a com-
patible 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 micro USB connector of the charging cable to the
micro USB socket of the headphones.
2. Connect the other USB connector of the charging cable to a cor-
responding socket of a USB power source (* to be ordered sepa-
rately). Make sure that the USB power source is connected to the
power supply system.
The charging process of the headphones begins. The LED display
indicates the charge status:
