... I'm curious about the griffin in-ears as a cheap backup. Anyone have those?
You mean the EarJams? I put a pair of those on my iPhone 3G headphones as an interim measure.
Pros:
1) Cheap ($12)
2) The Apple earphones now stay in my ears (they used to slip out when walking)
3) Sound is okay (but my ears are not as young as they used to be, so it's probably moot)
4) Provide some sound isolation.
5) I can still use the play/pause/back/fwd/mic features of the basic iPhone headset! Yay!
6) Come with a cute little zippered case.
7) Come with plastic 'shells' for both old and new ipod earbud shapes.
8) Come with rubber 'tips' for small, medium and large ears.
9) because of 7 and 8; I (big ears, new earbuds) and my daughter (small ears, old earbuds) benefit!
Cons:
1) Not insanely
beautiful. Insane, maybe

2) The rubber bits sometimes come off in my pocket.
3) No volume control !!!!

That'll cost $79 when the new Apple buds come out.
