These are awesome. Lately I tried another brand, and I'm coming back to these. They work twice as good as others, but be sure to get the ones that say "Quiet Foam" or you are only getting the quality of the other brands. My husband at a company that made the rocket motors for NASA and these are the ones they used. He'd have some in his pocket when he got home and I started iusing them for his snoring. *grin* I could still hear my kids call me and the alarm clock.
