I have tried 3 pairs of Samsung headsets, none of them works with Moto X. I mean I can hear the music, and the mic works too, but the control buttons do not. I just need a simple headset to answer/end calls, and play/pause/skip music, that's all I need. If your headsets work with Moto X, please let me know which one you are using. Headsets are not returnable once the box is opened. thank you very much.
