14. A hearing protection system comprising:
an earplug having a proximal end configured to be disposed in a user's outer ear and a distal end configured to be inserted into the user's ear canal, the earplug comprising:
a recessed cavity in the proximal end; and
a sound tube extending through the earplug from the proximal end to the distal end, the sound tube having:
a first opening disposed within the recessed cavity; and
a second opening disposed at the distal end; and
an electronic hearing device received at least partially within the recessed cavity of the earplug, the electronic hearing device having a speaker for generating sound, wherein the electronic hearing device is rotatable within the recessed cavity between multiple positions, including:
a first position in which the speaker aligns with the first opening of the sound tube, thereby permitting the sound generated by the speaker to propagate through the sound tube to the second opening; and
a second position in which the first opening of the sound tube is at least partially blocked, thereby at least partially preventing sound from entering the sound tube.
