Listening to some tunes, mindin' my own business. Using some Bose earphones. Go to change the track, pause music, change volume... nothing works. The fix: unplug the adapter from the phone and then plug it back in. The in-line controls start working again. Really annoying. Almost seems like it's a on/off trigger issue for the adapter. Haven't played around with different variables to find out exactly under what condition it's from but it happens all the time. My worry is going to the Bose or Apple store will be a waste of time.
