Abstract
A double hearing protection system comprises a circumaural hearing protector that covers and encircles the pinnae and an earplug device that is inserted into the ear canal. The earplug portion of the system comprises a tether that is coupled to the interior of a circumaural hearing protector. The tether retracts into the earcup when both the earplug and circumaural hearing protector are worn, ensuring that the earseal against the head is not broken by the retractable tether.
