Abstract: A wireless earpiece in embodiments of the present invention may have one or more of the following features: (a) a housing for fitting in an ear of a user, (b) a logic engine controlling functionality of the wireless earpiece, (c) a plurality of sensors reading user input from the user, and (d) a transceiver communicating with at least a wireless device, wherein the logic engine receives a selection of audio through the plurality of sensors, determines whether a tinnitus frequency associated with a user wearing the wireless earpiece is present in the audio, filters the tinnitus frequency from the audio to generate filtered audio, and plays the filtered audio to the user utilizing one or more speakers.

Abstract: An earpiece includes an earpiece housing, a processor disposed within the ear piece housing, at least one inertial sensor disposed within the earpiece housing, the at least one inertial sensor operatively connected to the processor, and a wireless transceiver disposed within the earpiece housing and operatively connected to the processor. The earpiece is configured to exchange inertial data with a vehicle having one or more inertial sensors. The vehicle may be a motorcycle, moped, scooter, bicycle, electric bicycle, personal transporter, hover board, or other type of vehicle.
