Earbuds falling out of ears. Is there a low-cost solution?

Hey everyone. I've got a dilemma on my hands... er, ears. I'm a cash-strapped college student but wound up with a used iPhone and brand new Apple earbuds w/ mic (I know I know, quality is crap). I can't afford a decent pair of headphones that'll actually stay on/in my ears. My right ear must be deformed because my left ear tends to hold the 'phone very well while the right one constantly causes the other one to slip out. -_-

Do any of you have a solution of some sort for this problem? I'd reeeally appreciate it. Thanks!
