Huge disappointment, avoid, do not buy especially not. Logitech would he make fun of the world for once?

I tested several hours and I put it back in its box for a return to sender.
The sound quality is more than disappointing ... nay, rotten. Listen to music or play a game with becomes unpleasant, it is to say. It was nice to try all possible settings, nothing to do. Also I am no expert sound but it seems that it is a false 7.1. I am very surprised because Logitech is my favorite brand for computer peripherals and I had never been disappointed before. So it is with confidence that I head down doing this purchase. It comes with 2 more strips of different thicknesses to the top of the skull comfort but they absolutely useless, completely off the Logitech plate on this one then! Also, I read that the microphone is fragile and may break in to take up the strength when not in use or when you want to transfer the pads and also the ears that will wear and s' crumbling prematurely in contact with sweat. Another thing, it has an integrated sound card also poor and therefore even if you have a great sound card you can not use it with this headset because once connected it is he who takes over. So a big zero pointed to this, if I could put him 0 stars I would.
I still finished up finding my happiness by buying bigben interactive MHS20 half the price, which is the best headset I have ever tested with a quality / price and monstrous that I awarded 5 stars (see my comment on the product). Astonishing as from bigben interactive which usually means very products. I recommend it anyway.
