This mic seems to be like the Dealextreme clip-on mic, without having to wait 10 years for it to arrive at your house (as long as you buy it from one of the American listings). Not sure on the quality, but it's worth a shot. The DX clip on will take like a month (trust me). I bought two of them on two separate occasions, and it took forever.
This is the lapel mic I bought a year ago, told you guys about it. Sounded better than my old platronics headset I had for my Xbox (which in turn sounded better than the official chat headset), so I bought a 3 pack and have been slowly giving them out.
Buy with confidence.
