Gamer headsets are gonna be pretty much garbage. Steelseries, Astro, Logitech, Razer, etc. All awful.
Get Sennheiser or Audio-Technica headset if you want one that doesn't sound like balls.
If you're gonna get wireless might as well get the cheapest one you can find, though... because no matter how much you spend it'll sound like ass compared to wired.
