Query: Nice design and price but a poor performance

I bought this headset as a present for my boyfriend to use it for VOIP with a bluetooth dongle and a notebook. I called him three times when he used it and after that I gave him the advice to return. The acoustic transmission for him was okay and I could hear his voice, too. But I and others who called him heard also a very annoying hissing while the call. He sent it back and uses his old his headset with cables again...unfortunately only 1 star.
