Excellent studio headphones, not flattering, good dynamics, excellent with a rare precision. I prefer the HD25 that I find much less comfortable.

- How long have you use it?
few months
- What is so special that you like most and least?
most, the sound
least, not yet found. It would have been a little more closed, it would have been nice but it is already well on that side
- Have you tried many other models before buying it?
yes including the HD25
- How would you rate the quality / price?
very good (it depends where you buy ... the Germans are very good at that ...)
- With experience, you do again this choice?
Yes, definitely
