The super human hearing (or what ever it's called) just boosts treble and volume (in my opinion) and only is available when it chooses to be.

If I press down the third time the volume could become super loud

You can control the volume of you own voice (low/high) as well as chat/game volume very easily

Make sure to choose the right mic volume setting for the type of room you're in, otherwise you'll have trouble being heard.

all it does is boost the volume.

Does what its meant to and the convenience of having the volume right there is awesome
