Very good!
The sound is more than adequate for gaming, these speakers make almost no noise and use almost no power when the PC is turned off so I don't bother turning them off.
I've read reviews criticizing the sound quality but these speakers are made for gaming, if you want to exhaust yourself with concert/nightclub type bass while gaming or you're looking for audiophile speakers to listen to music like a musicologist in a room with wooded walls, these are obviously not the speakers (nor the budget) for you.
I set the bass to minimum so as not to get even more tired playing after a hard day and the bass is still present, clear and distinct, even when I occasionally listen to music with it.
The highs are clear, I wouldn't go so far as to say crystal clear, it seems difficult to get aggressive/cheesy highs out of these speakers.
The midrange is quite clear and distinct, more detailed than usual on this type of speakers (but obviously less precise than listening in a recording studio).
One of the best choices I've made on this site.
