The reason most earplugs fail at night is simple: foam loses its seal. It expands unevenly, shifts every time you move, and by the middle of the night the snoring is back.
Hears Sleep uses precision-molded silicone tips engineered for a complete, stable seal that holds from lights-out to alarm. Snoring, traffic, the neighbor's TV reduced to a distant hum you can actually fall asleep to. Not "quieter." Quiet.
