[IceCube!]

Playstation and Xbox have this problem from time to time, or permenantly depending on the game. I personally find the more demaning the game is your playing the poorer the voice quality; I'm guessing the game creators have prioritsed you still being connected to the server as oppose to your voice sounding clear.

I can say from experiance, no what what mic you have; cheap or expensive everyones going to say you should like shit on alot of the games. I say the same back, in order to get around this meny of us just use Skype to speak through when playing a game together, however it does mean you cant shit talk the people your playing with.

Also if your mic is positioned too close to the playstation you wil get a humming or clacking depending on what console you own comming through your microphone. Really sensetive microphones near the Xbox tend to pick up a high pitched whine...

Bluetooth on the playstation also oddly tends to be clearer but hey this is all just personal experiance.
