All the free-floating bud types fall out of my ears, and I know plenty of others have the same problem. Look for some with a little hook that goes over the outer ear.

I have a pair by Nike. They have the ear hook. The other kind kept falling out of my ear.

& mine are Motorola Bluetooth S9....http://direct.motorola.com/hellomoto/S9/

they are linked to my ipod classic & my sanyo cell phone.....wireless, came w/different earbud "cups" for better fit, designed for athletes....they don't fall out, sweat resistent, behind the head fit......they don't hurt my ears like the standard ipod ear buds!!!
