I have tried many ear plugs, and Hearos are the best, they are very comfortable to use. They are soft and pliable, its cuts out the noise of snoring, Don't buy imitations because its not the same! Effectiveness you can still hear if something weird happens like someone ringing the doorbell. You learn how to differentiate the different noises, so that you can have a sense of peace while you sleep but not total deafness. Ease of Use just roll them in you fingers and put them in your ears, then they expand to fit the inside of your ear. Immediacy Just lay back and go to sleep. Side Effects none! You get used to wearing them and it becomes better than taking a sleeping pill, because it eliminates evening distractions.
