Motorola Motoactv :: Stock (corded) Headphones Not Recognized

My issue is that the red headset that came with the MOTOACTV unit doesn't get recognized. When I try to play music with them plugged in, it just doesn't do anything (play button doesn't turn to pause), and if I try to use the FM radio, it tells me that I need to insert a headset. I have tried to rotate the plug around, to pull it out slightly, or to push it in and make sure that it is 100% snug. None of the above actions have changed the result.

I tried using the MOTOACTV with another pair of headphones that I had, and had no issues playing music or the radio through them. So the unit seemed okay.

This lead me to believe that the headphones were defective, but when I plug them into both my ipad and also droid RAZR directly, not only do they work as headphones, but the microphone seems to work as well. So that kind of rules out the headphones too.
