Patent abstract
An earplug has a single very long main flange with a maximum diameter that is at least 80% of the length of the main flange, and at least 55% of the entire length of the earplug except for the stem. This allows the outside of the long flange to extend at a very small angle to the axial direction, and apply a constant force against the walls of the ear canal, for good and comfortable sealing to the ear canal.
