my missus bought a set of these Ice - they are nice, maybe to nice... i was used to my old crap headset that was from a PS2 game, worked on PC tho

.
could hear people sneaking round corners and through bushes and shiit... couldnt do that before - so sound quality is very good, also cant hear anything outside of the game - they block out all noise, and this is what i didnt like - i felt deaf to anything going on around me... This will be a positive to some people of course tho.
They broke very easilly for me - i think i stood on them, not very hard, and they never worked again...
Never tried the fatlity ones so cant comment
