I have a set of Dr. Dre ibeats headphones that work very well with my ipod. But sometimes when i use them on the desire I notice the remote controls ( play, pause, answering calls, etc) don't work for music and calling. When I press the button on the remote nothing happens. A restart of the phone usually fixes the problem though. Is this a problem of incompatibility or what? Why Dora it work sometimea and not other times?
