deficient, therefore a waste of money

Purchased headset in no way corresponds to the Artikelbschreibung.
1. The battery life of up to 192 hours can not be reached - even after more than a month with daily charging are no longer than 15 hours is possible, plus about 20 minutes of talk time.
2. The connection with two Bluetooth-enabled cell phones will not work !!! In talks with mobile phone 1 to connect to mobile 2 is lost, which must be made new again via the phone's menu then. Same problem arises in discussions with mobile phone. 2
3. Call quality is only inferior. Compared to Jabra BT 200, BT 250 Jabra Jabra JX 10 and v is the interlocutor is difficult and indistinct to understand.

Conclusion: Either I have a Monday device caught or Jabra has become very slack in quality. With all previously used Jabra Bluetooth headset I was satisfied.
