The headset is made of thin plastic, partly sharp-edged and the setting for the header size too tight and hakelig. The microphone is too quiet, so it can not be used for speech recognition. In addition, the sound is very dull and by the promised Noise Cancelling I did not notice anything. The sound quality of the head higher is average. The cable is not smoothed out, but is twisted and tangled constantly what totally annoying. For the price and the name "Sennheiser" All in all, an absolute no-go and go back!
