TRITTON AX51 Audio Xtreme 5.1 Headset TRI-AI712 in Canada at TigerDirect.ca
Thats the model I use. They were on NCIX for 69.99$ and were on special at boxing day for 20$! Really good headset, sound is clear and sound crisp. Only problem, it needs AC power... so you can't really use them on a laptop or as headphones for an iPod.
