I use Zagg smartbuds. Out of all the cheap ones I tried none worked or they worked only on one side. The Zaggs work although you have to plug them in and then unplug them a few times before the N900 recognizes that a headphone has been plugged in. They hang on your shoulders and do not fall off. Although to tell you the truth I have not used it in phone mode since I use my E71 for calls and my N900 does not have a SIM card installed.
