He deserves 6 stars

Sound: it slightly exaggerates bass, mids and highs are balanced and you have to spend more to get a better musical rendering (former sound engineer studio floor)
Micro: excellent for voice (spoken), no plops his clear and pleasant to the correspondent.
Ergonomics and comfort: the design date, but our heads were not changed, it is comfortable if a little heavy, you can fold the microphone to a purely musical use.

The cable is thin and tends to tangle, especially as Sennheiser have not been stingy in length, I have to spare ... but is still flexible and law as at the beginning.

The volume control dial still works without sputum despite the number of years, as the micro switch.

There was no particular rudely treated and still not suffer from false contacts only rubbers begin to age a little bit, but really just a little, I might change it in 7 years :)

In summary, I highly recommend!
