After a while, your ears get all hot, and the in-ear headphones tend to hurt after a while -- also, you can't judge the true absolute volume level well so close to your eardrums, and in-ear phones are more dangerous to your hearing than regular ones.

I haven't experienced this. I wear IEMs every day, and have worn them on 14-hour flights. Perhaps it depends on the person. In any case I don't see why they would be hotter (or hurt more) than silicone earplugs.

Citation? Given that they block more noise than other earphones, logic would dictate that you don't need to play them as loud to achieve the same clarity. I find that I keep the volume on my iPhone very low when I use IEMs, as opposed to near-maximum when using the supplied earphones or headphones.
