A wireless audio system suppresses exterior noise and directs desired sound into a user's ear canal. An audio system may include an earplug to create a seal in the interior of an ear canal. The earplug may include a ribbed exterior profile and can be flexible to create the seal. A speaker may be inserted within the earplug. A channel may extend through a body of the earplug to direct sound into a user's ear canal. A proximal opening may extend from the speaker to the channel of the earplug, and an audio wire may be connected to the speaker. The audio wire may connect to a wireless receiver, or other receiver, to allow audio data to pass through the wire and to the speaker, where it can be converted to audio that is passed directly into the ear canal of the user.
