"More-than-Satisfactory Sleep?"
I have found these to be pretty decent at blocking out most noises, and they're not entirely uncomfortable, but they're also not perfect. About 20% of them are a bit firmer than the rest, which makes them both less comfortable and less effective. I will still likely purchase these again, though perhaps not in this bulk format, but if you are super sensitive about noise or need to have the weird things stuffed in your ears feel just right you might want to look elsewhere.
