AirPods Mute Button on Case
I know that it wont be possible with this version of the AirPods as once you take them out of the case they bluetooth antenna is removed from the case.
However, how cool would it be if when you're wearing them for a call you could use the button on the case to mute/unmute calls.
I spend a lot of time on the phone as part of my job and once my phone locks, if I need to toggle the mute function i need to unlock to phone and go to the active call to access "mute".
