This headset has me - although bought used - not disappointed, because even after several years already use it still works like the first day. Rock music but you should not listen to full blast, because the device also transmits the above sound pressure. For online work on internet platforms, the use of the microphone works perfectly. There is no feedback or a change (distortion) of the spoken word. Conclusion: I would recommend this product good conscience and each only suggest to purchase not a cheap part for 10. The Sennheiser PC 151 survived at the time just the fourth Billigteil.
