I have this headset for 5 years 6 soon, no complaints.
Acute crystalline (a little too much for my taste), low well-rounded, medium a bit light but pleasant.
Ps: To all those who denigrate this headphone, please note that gentlemen is intended for hi-fi and not to mix, if you're not fucking tell the difference I wonder what you do in music, when the wise guy who finds a sony headphones at 15 euros a better sound than seinheser is that Mr. auchan uses equipment or even boost intermarché see, buy the real stuff and we'll talk.
