I used this headset for 6 years.
What I AIM least is its quality manufacturing leaving DSIR!
(See the reviews previous ones)
S'affesse foam, and the membranes were weaknesses in the low after a year and a half!
I bought it for the price of the reputable and Tecnics ... (probably a mistake ...)
In the era I do not really conaissait the diversity of headphones, the sound j'tais pluttnophite!
Before this I had an old Sennheiser headphones that sounded much better!
Raport quality fair price but no more.
Avoid the long run cost!
At the moment I work with the monitor speakers.
In the future I will deal plutt to another manufacturer guess who ...
