Paring worked without problems with my Samsung Galaxy Nexus, the device had to be previously charged via mini USB, however.
The wear dea headset turns out even after a long time not to be disturbing or uncomfortable with wearing no bracket I was not busy enough, but it should lt. Manufacturers using the supplied ear function in part.
The voice and sound quality can not be desired, the voice of the opposite is clearly what has also been confirmed to me by the relevant interlocutors. It was not even noticed that a headset is used.
The Noise Blackout also appears to work, at least in quieter background noise.
What was also important for me was the A2DP, which allows me playing my music through Bluetooth.
Battery life Operating approx 5-7 hours have not yet as accurate respected it, but long enough for my taste.
For standby time, I can not say anything because I on / off switch use to save battery power the small practical to use always.
The reason that the device only four and not five star receives is the range ... if I wear the headset on the right and have the phone in your left pocket there is connection dropouts, when I use the right pocket everything runs smoothly. .. Then I wear it just right, no problem.
If the mobile phone is exposed creates one ca 5 meters, provided there is no intervening door.
All in all a great headset to a, I think, reasonable price. I would buy again bund recommend it in good conscience continue.
