Disclosure: I received this product as part of an advertorial.
These earplugs have been very comfortable in my ears when I have worn them, they looked more like a hearing aide device to me once they were put in my ears. I could tell they were there more when I laid the sides of my head on a pillow because the ends of the earplugs kind of hit my pillow. I do not think they are made for sleeping though. I do not remember them coming out of my ears when I wore them like some other earplugs I have worn.
At first I thought that these earplugs were supposed to block out sound. They did not really block out much sound when I wore them, although I don't think that they are supposed to. One day I put these earplugs in and one of our car alarms went off in the garage. I noticed that the sound was pretty loud with the earplugs in but it didn't seem to hurt my ears. That showed me the purpose of these earplugs...to protect hearing. I know I will probably have a lot of opportunities to use these earplugs to protect my hearing during times I need to be able to hear what is going on around me, so I am glad they are washable and reusable because I plan to continue to use them!
My review= 5 out of 5 stars
