It turns out my new apartment is downstairs from a elephant that keeps odd hours, and the builders didn't believe in sound isolation. As I would like to be able to sleep, I've been trying to use earplugs, but it hasn't been working well.
So far, I've tried:
1) no-name foam earplugs: Hurt my ears.
2) Hearos Xtreme protection (foam): Hurt my ears less, but was still unable to fall asleep with them in.
3) Hearos Ultimate Softness (foam): Was able to fall asleep with them in, but woke up with sore ears.
4) Silicone earplugs: Mostly work, but I have trouble getting a good seal, and when I do, I end up with pressure in my ear. When I turn over during the night, they end up sticking to the pillow, then when they unstick, they wake me up. Still, they're the best I have for now.
My problem with foam earplugs is that they feel like I'm putting something too large in my ear, pushing against the sides of the ear canal.
Anyway, any suggestions?
