Try warming them a bit. Nothing real hot, just warm. Not sure where you're located, but if you could leave them in a place warmed by the sun (not around here, we're about 20 degrees F at best everyday), that might do it. Or sitting them near (but not touching!) a light bulb might. If they arrived crushed in the packaging, they've probably been in that state for some time, and they may not come back. If they get deformed too badly, they don't bounce back. If they don't come around, I would either return the IEM's or make a complaint to Shure to have them replace them for you. Shure is pretty good about customer service, they likely will take care of you without needing a return (as long as you bought from an authorized seller).
