I need a new pair of headphones but i dont want to spend a godly amount of money for professional headphones. Rigth now im using a $30 pair of Plantronics headphones that have served me well over the last few years. I was going through a game informer magazine and came across these headphones and I really like the looks of them and all the reviews say that they are an epic headset. However the problem is that it is USB. There is also a wireless version I currently have an X-Fi Xtremegamer sound card by Creative. Sound card has served me really well and honestly i think ive been using it since the S939 days. (i dont remember when exactly but ive had it forever) So basically im looking to you guys for help. I havent used anything but dedicated audio in all of my computers as onboard used to be complete garbage a few years back and i dont know if it still is or not. If I got those headphones I linked earlier, would it be worth it getting rid of my X-Fi sound card? Thanks.
