- How long have you use it?
3 months

- What is so special that you like most and least?
The +: the sound insulation from the outside: before I had to push my bass IAudio thoroughly and, suddenly, when the piece was at the height it saturated. No problem with the "headphone", I put the bass at least on my walkman and they are excellent in the headphone. In short, it's perfect for me.
The -: not very ergonomic foam but hey, I have not tried all the forms that are provided with, so my opinion on this point will be completed later. As against the wire gets tangled easily and the tube may tend to come off, I always managed to recover.

- Have you tried many other models before buying it?
Very little

- How would you rate the quality / price?
Excellent: frankly the sound is great and for that price you can tolerate the wire get tangled a bit ...

- With experience, you do again this choice? ...
Yes, I think, or else a slightly more advanced model in the same range (especially for returning foams up too fast for my taste and that keep me up well without too much pushing.)
