You're probably right, but I already have more than enough wires in here. I need to go wireless on something.
if you don't do a lot of voice chat, then you can probably go for a wireless headset. i mean, they work, but you'll have to charge them often and you run the risk of them cutting out in the middle of a game.
if you don't do much competitive gaming, then you can probably put up with wireless keyboards or mice. my dad had a wireless logitech gaming mouse that worked pretty well, but he left it plugged in to the charger all the time. then my sister got a hold of it for her laptop and somehow managed to fuse the receiver to her laptop's USB port.
if your wires are just a mess but you do a lot of competitive gaming and voice chatting, then cable manage that stuff.
