Rockbox

This feature would be for users with in-ear isolating earphones such as Shure and Etymonic. When the player is paused, the internal microphone would activate and play the recorded sounds through the earphones. This would eliminate the current need to remove the isolating earbuds for any sort of conversation, interruption etc.

Also cool would be a similar option which - instead of stopping the music - would simply lower the volume by a pre-determined amount before passing the recorded sound through to the headphones. This way the user can take annoying interruptions in stride. (This would have to be mapped to an obscure button combination instead of pause)
