Hi all. Im not really an audiophile, please help.

Im looking for a headphone for with my Sony Ericsson w580 and my laptop. My current Sony-issued earphone hurts my ear, so Im looking for something more comfortable yet portable. Budget: RM 150. Only for music and occasional movie. My audio collection consist of instrumental, jpop, jrock and such. Small, light headpiece and foldable design would be a plus.

Question; if I connect microphone-less headphone to my Sony Ericcson adapter I can still make calls, right? Thanks in advance.

Thanks for replying. Sorry I have to ask, is IEM the kind that goes inside the ear? If so, I prefer not to have those, cause personal experience with Sony's earphone makes me ear ache badly. And yes, the adapter have somekind of mic on it. I was thinking of buying Sony MDR-410LP but dont like the headpiece design. Any suggestions?
