- How long have you use it?

I used it one week (2 evenings wholesale)

- What is so special that you like most and least?

The +: the size of the headphones
the -: sound quality very poor (no bass comes out, that high) and lack of soundproofing (I'm DJ and I could not hear the sound in my headphones when he was a background)

- Have you tried many other models before buying it?

nan and I regret

- How would you rate the quality / price?

too expensive

- With experience, you do again this choice? ...

I have not brought a darty xD
