Helmet received! After unpacking quite restrictive, I snatch me at all who likes to keep packaging to a hypothetical resale ...
Installing the drivers using the Logitech site (I have no cd player ...), immediately recognized by my windows 7 64bit.
Launch mumble to talk with friends ... Result they hear me perfectly and I hear the great!
In short that you ask?
A little problem helmet makes me ears hurt after some time. I should probably change the cushion at the arches to adjust properly to my head. And the helmet must be done as I think.
In short I am very satisfied with the headset, Logitech is a very very serious brand.
