I just purchased a sony bluetooth headset for my ps3 yesterday and i can't seem to hear anybody when they are talking through the headset only from the tv. I can speak through it but i just can't hear from the little speaker. I have only tried it on MW2 and on GTA and i can hear through the speaker but when i tried it with my phone i could hear perfectly fine. Is there a setting that i have to change in order to be able to hear from it?
