Headphones vs Speakers

[infinite loop]

I've currently got my setup where I use my 4.1 speakers and a headset for a mic, for TS. I tore the earbud off my headset so that it doesn't cover my ear, but it fits akwardly on my head now, and isn't comfortable. I prefer my surround speakers to headphones. For those of you who also use speakers, have you found a headset mic that comes w/o headphones, so basically, just a mic? Or otherwise, is there a good desktop mic that will work and not pickup my speaker noise?
