I have inadvertently become an expert on earplugs when I discovered, 6 months ago, that my insomnia could be cured, simply by using earplugs to block out noise. I have tried most earplugs that are sold at the pharmacy that block 30db or more. These do not have the best noise blocking capabilities BUT they are the easiest to insert, they are comfortable and they definitely get the job done! I repeat, they are not «the best» noise blockers BUT they 100% do the job. I will be sticking with these are they are the best value and comfort. For those of you who live in «very noisy» areas and/or want to block out all noise, I recommend the pharmacy ones that are orange. In my opinion, those block out the MOST noise but for me are hard to insert, often pop out and are more expensive. Enjoy!
