that is why these headphones are regarded as one of the best for COMPETITIVE gaming, where bass can be a distraction or drown out footsteps.
combined with the wide soundstage and quality, they are easily in the top tier for gaming.
if you don't plan on using them for competitive gaming or you don't take your gaming that seriously then do the mod. i bought mine for gaming so I'm keeping them stock. I have HD600's for music.
