Funny, though I don't use them (I carry them as spares), Apple earbuds fit my ears like they were designed for 'em. I imagine that I have very Jobs-ian ears.
Then again, I can step into a 40 Regular suit off the rack and all that they need to do is hem the pants and sleeves; I am Mr. Normal.
You know what would have been cool? If they included a Bluetooth radio and allowed you to pair to a
Nike+ Watch Remote. I actually use one of those when I run, and it's great.
