I own the Sharkoon 5.1 V3 ones. Absolutley brilliant with true 5.1, not simulated. Placed a mini review on here if you search. Go to Sharkoon's main website to see many, many, awards for these. Once all the kits attached you have just 1x 3m cable for the headphones, tiny decoder and other cables can be 'tucked' out of site. Also a review on
www.trustedreviews.com.
Purchased for £119. Gaming is wierd without them now. Can be used with DVD, BD player, Xbox, PS3 and PC and includes a detachable mic. You can even add a PC speaker kit into the tiny decoder should you want to upgrade or use speakers when possible. Haven't bothered with that though, great as they are.
