I use it for 3 years

- Comfort (comes with 2 interchangeable earpieces -fabric or imitation leather, has deconseiller to those who sweat ears: p)

Most

Mobile -ecouteurs
- To the top, heads the sounds of beaches are well rendered.
-l'adaptateur 6'35 jack that screws and do not eclipse: ca tiuent and you do not lose it!

Cons:

Attention all the same has a certain fragility at the head clamp (a few cracks, but hey I made him see what a headphone).
models essays:
-before this one at Sennheiser HD200 (a greenhouse head brutal, the most tiring headphone that is) and HD25 (headphone monitoring fabulous, but with an output level and too heavy insulation: tiring)

- AKG studio: A reference, but listening, I have not liked sorry (AC headphones, you have to try again and again)
-Beyer Dynamic DT 770: excellent
Quality price ratio: good (a bit expensive), because I have consumed some previously headphones
HD200 (+/- 90), I flingu lot of headphones in a year, and it's worth the cost to invest more expensive ok, but this one is solid.

- Again the same choice: YES !! or DT770
