Headset Voice

My xbox 360 headset can barely pick up my voice?
i just bought a new xbox 360 S and tried to play some reach and mw2 and it can barely pick up the sound of my voice (in games and party chat, its all the same). i have to shout a bit in order for my teammates and other players to hear me. is there a way to increase the sensitivity on the microphone of the headset?
What has that got to do with an xbox?
and yeah its something wrong with your mic you may have to teat it on another controller just to make sure otherwise buy a new one as they’re only around a fiver or something like that
