- How long have you use it?

For the past six months. Accuracy should be noted: I do not use a professional at all. I am a student, I used to listen to my music during my trips, and work on musical projects at home. (I win so often with friends, with whom I mix two to three tricks).

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

most: _ the looks
_ The bass
_ Treble and midrange present without being aggressive
_ Pack very well (cables, adapters screw (which is often lacking), and also two different types of foam ...)

Cons: _ comfort (we can do better): the ear cups are too small and are not sustainable over a few hours ...
_ The overall strength (at the beginning I brought my bag to ds after class, but I stop because the headphones, even in its protective bag (supplied), did not take one month ... )

- Have you tried many other models before buying it?

I tried most of the range Sony headphones, I found good, but nothing more. To buy the Numark (www.musicstore.de on), I relied on the technical characteristics, as well as price: I got it new for € 53!

- How would you rate the quality / price?

Exactly, the price seems very correct to use that I have, that is an amateur use, in terms of leisure ... € 53 for a closed headphone for a customer to pro semi-pro, it suited me very well.

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

I think so. In addition to the (small?) Disadvantages that I have noticed in the test, the headphone as a whole seems suitable for my use ... As for professional use, I read in other reviews of the rave reviews decided that I can fully understand.
In other words: a good headphone for an amateur customer.
