I love these earplugs, they are much better than the 3M. They fit snug but are soft so not to irritate inside your ears. I have to wear these going to sleep and wear them most of the night and they work and feel great. These are one of the best earplugs out there, and most often I use them 2 - 3 nights in a row so they do last a long time. So if anyone is questing what ones to get, get these.
