Guys, they suction perfectly onto the ears. At first, when I saw how tiny they were, I thought... how much will they protect me and how stable will they stay so they won’t come off in the water? I tried them and was pleasantly surprised. Effective, you hear very little of the outside sounds; I’d say they eliminate them. And in the sea I didn’t feel the water entering the ear opening. Get them and you’ll remember me.

very good, easy to put in and take out compared to some others. ps. I have a very small ear opening..

Very good earplugs. They fit me perfectly, my sister also has the same ones and she is very satisfied too! I swim for an hour in the pool and they don't go anywhere! I recommend them.
