I purchased this product in order to use it as a headset to my phone and my computer. The headset is well made and the first couple worked without problems. After being charged, I did the first tests, which unfortunately brought forth a sobering result. The touted by many clear voice quality I can not confirm. Both the phone and the computer sound Skype conversations but very modest. So I got a little busy with the sound settings myself. There are two modes even mono audio and even A2DP stereo. In stereo mode, the sound is then very convincing, everything is reproduced clearly. In Mono mode, however, it all sounds very washed out. Although one can not understand anything but the quality is of a normal USB headset while "skype" very far away. Unfortunately it is not possible to use the headset microphone when you are in the A2DP mode. What good is therefore good sound reproduction when they can not be used in conjunction with the microphone. The headset may completely normal telephone calls are sufficient, which in the sense is indeed the cause for Skype conversations, the quality of sound transmission in my opinion, insufficient.
