Farflungheel 4 Due to some new sounds in my environment and possibly to greater sensitivity for some reason, I've come to like using earplugs when sleeping. I've been using the standard foams ones, but found they often either came out during the evening or lead to my ears aching when they remained in. These silicone plugs work far better for me. It is easy to shape them to fit one's ear, they don't expand and pop out or cause pain, and they block more sound (I gave 4 rather than 5 because I wish they blocked even more sound and I'm a tough grader!).
