I can sit still and the stock iPod earbuds fall out of my ears. They're useless. I bought the Nike ones that loop behind your outer ear and they suck too. They don't stay in place, and they just slap against your ear when you run. They're ok if you walk or jog, but if you run like an actual man they come right out.
In HS I used to run with a Walkman. Yes, that huge brick that played audio tapes. I used a full headset with it and it NEVER came off my ears. I might go back to that. I'm tired of f*#@ing with my ear buds 20 times during a 3 mile run.
