- How long have you use it?

I use it for the past one month, for use as a Dj Extreme, STATING THAT THIS MODEL IS MADE FOR DJ, NOT to walk just to listen to MUSIC MP3 PLAYER WITH HER
- What is so special that you like most and least?

The +: Its Ultra comfortable foam, insulation from outside noise really be powerful, maintaining his perfect head too high or make a wrong, or not enough to hear all the noise ... Ideal length of wire (3m) which can be shortened by using a simple elastic (obviously you need a minimum of savvy ...) And finally, its sound quality really really good, maybe a slight increase low but otherwise it niquel = D

THE -: What I find regrettable is ... euuuuh, not having to buy more!

- Have you tried many other models before buying it?

Yes, I try multiple SONY, but the foam begin to "settle" after the first month ...

- How would you rate the quality / price?

I considered excellent, Dj For beginner, see vraient confirmed that a deal for 60 euros in stores, on average, you can go there with eyes closed
- With experience, you do again this choice?

Obviously, without a shadow of a doubt =] Especially with Senneiser's reputation, quality, price sold off as they say!
