For wired headsets, you can use Intent.ACTION_MEDIA_BUTTON as mentioned in the other thread. This is how the built in media app does pause/play on wired headset button presses, and where I recommend that you hook in.
For Bluetooth headsets, they do not work like you think. There is no 'button pressed event' sent by the headset. We don't know when the button is pressed. Instead the headset maps its buttons presses to commands depending on its state machine. We receive commands, not button presses from the headset.
