How long you use it?

It'll be three and a half years very soon. Especially for the electro mix, but also for listening to movies and some composition.

What is so special that you love the most, least?

The pros:

On his very correct and not tiring in the long run.
Very good light on the head
Pretty nice for mixed because it is very light.

The -:

As long as it is fairly easy listening uncomfortable because of the length a bit small, even setting up (I have a small head and eye)

Did you tried many other models before buying it?

HD200 very comfortable and perfect for little ears

How would you rate the quality / price? With experience, you do again this choice? ...

The price / quality ratio is very good, I do it again this choice without hesitation.

After three years, I just made a connection that few bad contacts at times but nothing major.
