- How long have you use it?
Since June 2007

- What is the particular feature you like best and least?
I particulirement will appreciate the power of sound (not against trs suited to monitoring).
Comfort is falsely Submitted: the 1st time you put on the ears, is "wouaw" ... APRS 20 minutes, it's "Ae, bobo" ...
The quality of manufacture is a real sham: trs nice and solid, this headphone is really fragile. I broke a wire strength of internal wear store in the splendid cover. It is also impossible to change (pice dtach connection pro-found and Sony (impossible to do a weld)

- How do you report qualitprix?
Trs excessive, given the low manufacturing quality and comfort.

- With the exprience, you do again this choice?
Certainly not (I dtest Sony + in +).
