EarJellies are the most comfortable earplugs I have used so far.
It's nice that these can be reused and even washed, but they have a regrettable tendency to return to their original shape, which is much too short to go very deep into the ear canal. Since they're not seated very deeply, they can't provide the attenuation if a longer earplug. I get significantly better performance from closed-cell foam plugs (specifically the Howard Leight "Laser Lite" plugs). They're disposable, and not as groovy as the Ear Jellies, and they can invest themselves occasionally if you roll over, but the attenuation is much greater and they let me sleep through the night.
Wife and I snore more in our later years. I find that the Ear Jellies fit well in my ears and really block out sound well enough that we can sleep in the same bed most nights. Love this product.
I ride motorcycles and worked a grave shift for years, so earplugs matter, and I have difficult ears, so it's hard to get comfortable ones. Extremely comfortable, and very good at blocking voices, they block mid and low sounds better than foam earplugs.
