I'm looking to up my cardio so I've switched from the elliptical to the treadmill. Problem: my fucking ear buds do not stay in my fucking ears. They are the little rubbery ones, but the ones with the foam don't work any better. I have tried various sizes of the rubber attachments and no success.

What do you use?

I'm looking for cheapish headphones because I am terrible about misplacing them.

Halp! I need my audio books to keep me motivated.
