I have a 40gb PS3 and I bought a Plantronics Explorer 233 from my friend so I can finally talk online when I'm playing. I have it paired up and everything. The only issue is that MW2 says that I don't have a mic. I'm not even sure if it's on or not. It only has a red and blue light, and when it's in pairing mode it flashes red and blue. No green. It is bluetooth connected and it didn't have a usb. I don't have an instruction manual, and before you ask if it is charged or not, it is fully charged, I charged it overnight. Please help.
