How to make IEM more comfortable?

I have always tried to stay clear of IEMs because they hurt my ears after a few hours.  I stick with my full sized to game and watch movies and IEM to listen to music.  I was recommended to use Foam Tips to help, but those actually make it worse.  Is there anyway to make it not hurt the inner ear after a while or is that just common?

i am used to it in a certain extent, its just when i pull them out my ears hurt so much.  i think its because they expand my ears.  i can tell that my ear canals and stuff are wider than they were before i think.  maybe its all in my head, no pun intended.  i think its just the nature of iems though.  having something in your ear for that long is going to cause some pain.  full size phones dont really give you pain unless they clamp hard.  the ad700 were the most comfortable headphone i ever had a chance to try.  the hd555 isnt far behind it though.  the modded hd555 is basically what i want, just more detail and a little more bass.  but they are the best all arounders i have come across in the low-mid price range.  the highest high end iem i have tried were the re-zero.  i have a pair of re0 now.  cant wait to test everything on the new fiio e10 amp i preordered.

yes this is true about some iems.  some hurt more than others.  but i have always used the single or dual flange silicone plugs.  have tried the foam ones which should have been more comfortable but none of them fit well enough/

eh i have been reading and i have ordered the foam earplugs you use for sleeping.  i read a site where you cut them in half, poke a hole through and they are just as good as complys.  so i am gonna try that.  i don't really have any other things to try, thank you!
