Abstract: A wireless earpiece having no venting port extending from the interior of the earpiece housing to external to the housing on the side of the housing towards the earpiece wearer's ear. The earpiece has a housing defining a front cavity and a back cavity, the front cavity proximate a wearer's ear when the earpiece is positioned in the wearer's ear during use and the back cavity away from the wearer's ear when the earpiece is positioned in the wearer's ear. The earpiece has an audio output nozzle extending from the front cavity configured to extend at least partially within the wearer's ear. In some designs, the earpiece has no vent extending through the housing toward the wearer's ear when the earpiece is positioned in the wearer's ear, but may have a vent extending through the housing away from the wearer's ear when the earpiece is positioned in the wearer's ear.
