Logitech G51, the speakers are beastly, i actually didn't pay for them, got them for free from Blizzard cause i had one of my screenshots make it for the wintervale season. speakers go aling with my g15 keyboard nicely. used to use the logitech x-530, but gave those to my bro.
If i mistakenly leave the sound up, its always a treat for my roommates when i load a game.
