I've owned and tested the Tactic 3d Omega
for around a year now, and couldn't be happier with the sound quality. it's compatible with PC, Mac, xbox360, and ps3, so you're covered on that end, and it has a great soundstage. tritton used
to be good but lately i dont know, they don't seem as good as they used to - plus ive heard their support isn't the greatest. but yeah the omega's are good for multi platform gamers and i'm lovin the wireless
you might also like the astro a40s or a sennheiser pair. good luck!
