does it need to be a headset?
my personal suggestion would be to buy a pair of ath-m50s for $105 on ebay right now and get a $35 desk mic, clip on mic (clips onto cable) or modmic (boom attaches to headphones)
I'm only interested in a headset. I hate desk mics. I've been wanting to have different headphones for gaming. The models I mentioned look great, but I hear mixed reviews.
