The Share button doesnt work, since that seems to be a PS4 function only too. I couldnt tell you about any additional noise, as I have a hearing problem to begin with. They are higher quality than I would expect from a set 2-3x the price. Are they totally perfect headphones ? No. I feel that would be very boring to try them all consecutively, but this might be a game that you can pull out from time to time and quickly play through to see something new. - Lowering the volume or pausing is annoying as the button is not as responsive or immediate, so that means you remove the ear cup to listen to people asking you "is this your last set?", that gets annoying because it causes the band to snap off. you wont be disappointed with these. So, this thing just killed my two Move controllers (4 months old), my original PS4 controller, and the new PS4 controller I bought 2 months ago. The Birkenstock "soft" footbed is anything but. Edit: I was at a store yesterday and tried on a few shoes; somehow, the 8s fit me and the 9s were huge.
