I have a $20 dollar Radio Shack headset that I use for CSS. It's very flimsy, and the pads that cushion your head are starting to fall off, but if you're broke and looking for something affordable; find one similar. The microphone part of it still works great, and I've had this for a few years.
Yea i had one were you had to move the wire around to get any sound ......it sucks
