I used these ear plugs for almost ten years. They were expensive but I slept through college dorm parties then my husband snoring, etc, etc. Then about a year ago, my ears started itching badly then hurting. I had an outer ear infection. Cleared it up, bought new ear plugs and got another ear infection! I realized that these things were suddenly giving me ear infections. No idea why it happened then, but my husband never could wear them for getting and ear infection. I always thought it was a fluke for him and I was immune, but then I realized not! I do not recommend using these long term. Maybe if you're on a short trip and need rest for a night you'll be okay, but please don't use them long term like I did. My ears still itch sometimes though I no longer have an ear infection.
