Normally I don't use anything particularly special. If I'm playing music on my computer, I use the built-in speakers most of the time, and whatever headphones/earbuds I happen to have on rarer occasions. About the only thing I use for portable music, and not that much, is my PDA. I have to plug headphones/earbuds into that, and again I use whatever I have. Right now, it's a Sony brand of earbuds that wind up into the case.
