I did a lot of research on these things and all I heard was good praise and such.
My problems are that (1) the bass is just to 'effin heavy, it takes all the other sounds from MW2 and leaves me confused, (2) Everything is either too high pitched or low pitched, and (3) all the sound is dull and lifeless EXCEPT for the bass.
I have tried several settings, I have tried resetting the mix box, and I even tried playing different games (I mainly bought it for MW2).
No luck! Any help would be great. Thank ya. :)
