I had this issue, but it seems to have stopped. When I plugged in my new Sony earbuds, the icon appeared in the notification area as if I had plugged in headphones with a mic (which my earbuds don't have). Songs would randomly fast-forward, the dialer would open, google voice search would start, etc. I unplugged and plugged in several times and the icon switched to regular headphones. No more issues so far...
