Need help looking for a Microphone for gaming.

People will say to get a standalone mic and standalone headphones, but usually a headset will do just fine. Unless you are an audiophile.

Genius Cavimanus

I'm personally using this, and it provides great quality sound for ~60 bucks, with built-in rumble for extra bass effect.

Headset with a mic if it is for gaming, from there it depends on how much you wish to spend but make sure it has a long cable and adjustable mic.

Clip on mics are the way to go.
Headsets usually have terrible audio quality.
This is recommended by many

I just use my 360 headset through my gamepad. Works well enough at least. As long as people can understand my accent, the audio quality doesn't cause any problems. Lets me keep my money for more games since I already had one anyway.

I own a Logitech G35 gaming headset and it's really sweet for gaming and music. The audio quality of the Mic is also pretty good.

Headset gaming mic is probably the best for gaming purposes. I personally opted for the music route instead. ATH-M50 and AT-2020 :)

Turtle Beach Earforce P11 is what I use.
Didn't break down for about a year if you take good care of it.
