I use the SteelSeries 5H v2, and I'm really happy with it. It's very comfortable to wear, and doesn't hurt your head or ears during long duration gaming sessions. It has a retractable mic that hides in the headphone itself, for when you're not using it and the sound quality is decent.
It's a bit over your budget at about $79.00 dollars, but considering that a lot of mid range to high end gaming headsets easily retail from between $250 to $400, I'd say that this one is reasonably priced. I think it's worth the investment! Good luck in your search!
