- How long have you use it?

6 years

- What is the particular feature you like best and least?

most
extremely clear and neutral prcis. frquence is not overexposed. the sound is no default.
closed perfectly suited for recording in noisy environments. I had the opportunity to test it when recording outdoors on dat or zoom h4 (voice taking on station platform). it allows monitoring comfortable.
small, lightweight and unbreakable. the first one I had in the hands of the silent cole abused by levs for over 3 years without flinching.

the least
the wire is actually Gnant. you have to gaffer or simply return the headphones

- Have you tried many other models before acqurir?

AKG I do not know which (heavy and too open)
grado
beyer dt990 DT100 (too big but comfortable)
Sony (too fragile)
Cheap apex (IDAL for sound recording in the rain or skater ...)
seinnheiser few open and HD25 70 ohm slightly more bulky and expensive, but not the problem of wire.
- How do you report qualitprix?

a headphone is expensive but the guard screws. both headphones have a home is an HD25 and am HD25sp (more portable when you want the sound recording collection outdoor) and a Grado SR80 for MUCH fun.
- With the exprience, you do again this choice? ...

for a closed headphone is less than 100 euros so no problem. Now I have the means to afford the luxury of a single cable I will buy the HD25
