sennheiser 215hd for me... why u'd get anything but sennheiser or another dedicated audio/sound company is beyond me.
no it doesn't come w/ an attached mic... but the rare times i do scrim...i jsut wire tie the mic around my headfones.. i have the added benefit of not lookin like i'm outta my element when i'm wearing them out (poker, subway, etc)
IMO with 80$ as budget is kind of a stretch to buy a headset that sounds good, has good sound quality, powerfull bass and it's solid. That's like the impossible mission. You should either buy a pair of decent headphones (Sennheiser, Audio Technica, Beyerdynamic) with a clip on mic (the Zalman clip-on mic is quite popular) or increase your budget and buy a Sennheiser headset (i know they're expensive).
I made the mistake to buy the Siberia V2 USB black at the time they appeared and I regret it even now. At that time I could have bought Qpad qh 1339 (one of the best headsets - not in production anymore) if I only had researched properly and with a little add-on to the budget.
