My experience with the headset:
Plus: low, actually stereo, A2DP works (music continues after the call)
Minus: Making calls is only available with the supplied headphones as possible because the microphone is installed
and the supplied headphones are suitable in my opinion not for music
When I use the Sennheiser CX 300 is connect to endure the quality (it roars)
There is no battery installed only battery Micro AAA possible (but you can also insert a battery)
Dropouts, but can not say whether it is on the headset or touch
In conclusion: just as pure headphones so fine, the price is the Kracher
