As it is with the PS3 you can go to your console settings and adjust the sensitivity to either level 5 or level 1. At level one you have to shout into the microphone before it transmits to other players, at 5 you don't have to shout.
The Xbox 360 does not have the ability to adjust the software settings, and getting a more sensitive microphone is pointless because you still have no control over the sensitivity meaning i still cant whisper at night when i need to.
so i'm asking the community, how do i get feedback to Xbox? i would also like this on the One.
