Abstract: An 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 driver may be inserted within the earplug. A distal opening may extend from the speaker driver toward the distal end of the earplug to direct sound into a user's ear canal. A proximal opening may extend from the speaker driver to the proximal end of the earplug, and can receive an audio wire connected to the speaker driver. The audio wire may connect to an audio device 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.
