Abstract
An apparatus and a method of making a corded earplug, including a flexible cord material and a pair of earplugs. Each earplug has a nose portion for insertion into the ear and a rear portion extending from the nose portion and lying outside of the ear when the nose portion is inserted into the ear. Each rear portion has a pair of openings physically displaced from each other and/or angularly displaced from each other. At least one of the openings extends through the rear portion. A short portion of the flexible cord material is inserted through the at least one opening extending through the rear portion. The short portion of the flexible cord material is then inserted into the other opening to have the short portion of the flexible cord material physically displaced and/or angularly displaced along its length to lock the flexible cord material to the rear portion of the earplug.
