Abstract: An earplug includes a housing and a receiver positioned in the housing. The receiver may be configured to receive a wireless audio signal from an audio source external to the earplug and convert the wireless audio signal to an electrical audio signal. The earplug may include a speaker configured to receive electrical audio signal from the receiver and convert the electrical audio signal into audible sound output from a speaker port. The earplug may include a projection including an opening that defines at least a portion of a sound channel from the speaker. The projection may receive the audible sound output from the speaker and output the audible sound out of the earplug. The earplug may include earplug padding configured to form a seal with a user's ear canal. The earplug may include an acoustic vent positioned in the sound channel, including a waterproof membrane extending across the channel.

Abstract: A communication accessory may include an ear cup configured to at least one of send and receive an audio communication. The ear cup may be detachably coupleable to a first accessory coupling system configured to couple to a helmet and a second accessory coupling system configured to couple to a headband.
