Best voice quality headset for around $50.

So I basically had a big ol' long detailed thread typed up, and forgetting to pick a sub-category when clicking submit kinda ruined everything. So I'm going to type up something new in about 10 seconds.

I want a good headset for around 50 bucks, I don't care about the audio quality that I hear, but I do really, really care about the quality voice that my viewers will hear. Comfort is a big plus, however I'll take a comfort hit if it means better voice quality.

There will be lots of clicks, keyboard mashing and computer fans going crazy as I'm live broadcasting and I'd like to keep as much of that out as possible as well.

I appreciate any suggestions.
