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.
