Most people probably haven't noticed this and probably don't even care. The somewhat mediocre headphones that come bundled with iPhones, you know, the ones with the button for music controls? Well, they have a wierd side effect when paired with the Adam. The middle button has to be held down in order to hear music properly. Without the button being held, the music sounds garbled like a bad youtube video. This isn't a major issue by any stretch, but it is most likely hardware related. I don't know what causes the problem, but I do know a solution. A clothespin. Yes, a nice string clothespin to keep that button good and smashed.
