Can someone suggest a good mic/headset

That will connect to the ps3, and work on my computer as well? I have a couple bluetooths, but I don't the model works.

I have the Bluetooth NS-BTHDST headset with a compatable USB port that came with it. I got it for $60 at Best Buy and it works great for my PS3 and Computer. It has around 12 hours worth of use between charges, and has a great sound quality. Plus it is very comfortable and leightwieght so you don't really even notice it's there.
