G430 is surround sound headset. Or at least it pretends to be. I have not found any good surround headset up until this moment that are at a reasonable price. Tried the G430 and tried some Creative Crative3D but it was horrible. The bass was murky and muddy and the overall sound quality was rather bad.
Then I got a G230 - good old analog stuff. Using them for the past year - couldn't be happier. I vote for G230 - better than most of the headsets for the price.
