Go with Degtyarev's post, if you want to save some money.
But if you want something more costly and more features, choose the Astro that Deathstrike posted.
Specs:
Really...?
But astro headset looks like mediocre quality, and paying for the name and looks. For the price, even from a headset I would expect more (as in, the only feature is the mic and
virtual 7.1)
I still recommend getting the zm-mic1 and a pair of headphones to save yourself a lot of money and get a better quality. You could even find a pair of virtual 7.1 headphones if you so desire, but I urge you to stay away from the headset area, unless its a generic 10 dollar pair, since as I said, the crap quality mic they slap on headphones bumps the price up a few hundred% more often than not.
