I am actually a friend of brands, I thought to myself that it's not bad may be for my laptop and it installed VoIP solution from Cisco to use a Sennheiser Set. The processing of the headset is good, it is pleasant to the head, but ... When dialed I could my Opposite always clear, albeit quietly listening, but heard my voice wavering and choppy. All settings did not help, I was partially inaudible despite slobbering. That would be for me a criterion return the headset, but again Skype angeschmissen and voila is not brilliant but good. For the price acceptable and therefore retained.
Nevertheless, only 3 stars, because a real phone solution can not operate the headset.
