- How long have you use it?

Been used for more than 5 years in home studio or traveling.

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

+: Excellent sound, good quality, good isolation from outside noise. The model I is strong: it is the only one I ever owned (except walkman headphones but nothing to do) and hold out despite the years, falls, sometimes much storage in the compressed backpack ...

-: Color flash too (mine is metallic gray), aspect "plastoc".

- Have you tried many other models before buying it?

not

- How would you rate the quality / price?

not bad (cheap) but I am not an expert.

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

Yes to begin is a good headphone. Now my next headphone will probably be something with a more "pro".
