I just got my first Droid (Droid 4) and I'm trying to figure out how to plug a headset in. It looks like I should just be able to plug a 3.5 mm headset into the top but the plug only goes about half way in and then stops. I am, of course, somewhat reluctant to apply significant force. What sort of wired headset can you use with a Droid? I was hoping to be able to use my stereo headset/microphone combination that worked so nicely with my previous Motorola Razr Maxx.
