Update:
After prolonged use, I prefer something from two stars. The reason for this is the poor usability.
1. Taking serving headset from the charging station, it is by no means so that these faint and the base station is switched on.
- You have to first switch on the base station
- And then the headphone
2. The buttons are arranged in particular the unfavorable for the volume. Either Hitting the power button or one of the two Ballanceregler.
3. The Ballanceregler is quite unnecessary and should if at all be on the base station.
