Good earplugs?

I struggle quite a bit with noise sensitivity, specially inconsistent noise, seems like I keep focusing on it a lot. Because of this I tend to use earplugs at lot, specially to sleep as I struggle to sleep a lot as it is. I have been using the same earplug brand for years which is pretty nice but recently they have changed it seems and it hurts my ears a lot when I wear them, the noise cancelling doesn't seem as good either. I was wondering if anyone experiences the same and has any tips or knows some good earplugs I could try.
