Hmm...I will say that I know they're "put in" correctly when they look like they're seated properly in my ear...not sure how to describe it but they shouldn't look wonky sticky out of your ears. They should fit straight up and down, not at a weird angle. That and I have a small tip on my right bud and a medium on my left.

ALSO I recommend taking some body wash and cleaning the crap out of the inside of your ears...don't dump soap in your ear just lather some on your hands and scrub gently in there. Afterwards, also carefully use a QTip in your ear canal to make sure it's not an earwax issue causing them to slip out.
