Playstation mic important question!! need heelpp

What mic should i get. Right now I am using my motorola S9 which is for my phone. But i can connect it to my ps3 and use it for online gaming. Now the problem with that is when i, using my mic, it works PERFECTLY with Killzone 2. BUT when i try to use it with Metal Gear Online im not anle to say anything. I can only hear. Now I was going to buy the Wireless Blutooth that came with socom confrontation because hopefully it might work with MGO as well all my other games. Any suggestions?

Thanks,

Your two best options are.

The official PS3 wireless headset.

Or if you want cheaper

The Logitech Vantage USB headset.
