Sound is excellent, both recording quality, and playback.
Now comes the great and only catch:
The microphone had a defect after one to one and a half years. If you waved the microphone arm down (so the microphone was also activated simultaneously), was the interlocutor a very annoying noise. The first was so overcome by the microphone swings up and down. After a very short while, is no longer sufficient and that you have to spend a lot of seconds in order to make the microphone rauschlos. At some point it no longer is. The first device was sent to me by the warranty directly spare - class service from Sennheiser. Now, by this time only nine months is the same defect appeared exactly. Exactly the same thing. Now uses no guarantee more. Thus, the headset is already no longer be used after two and a half years. Waste of money and big annoyance.
The same error also came with a friend on and with his nephew. When nephew now the guarantee instrument.
So this is a defect in the mechanism which occurs after not too long ago. Of course, the defect does not occur so quickly, if you use the microphone rare.
Previously, I had a Sennheiser PC151, which provided me with six years proud service, without any defect.
I am very disappointed about this headset. Everything else goes well, but without a headset microphone is only one more expensive headphones.
Sennheiser gladly again, but not this (or similar) model (s).
