The only reason I didn't give them five stars is because I can hear my husband's snoring, but it's muffled enough to get some sleep. They completely block heavy breathing and light snoring. What I like best is that they fit great and are easy to put on and take off. I trimmed the length a bit and found that this allows for better sound deadening. I think this is my second order in maybe 18 months so you get a lot of wear and tear for your money. I've tried wax products and like them a lot more. I would recommend you try these!
