An earpiece includes an earpiece housing and a location receiver disposed within the ear piece housing. The earpiece is configured to determine location of the earpiece using the location receiver. The ear piece is configured to generate three-dimensional sounds based on the location of the earpiece relative to location of one or more sound sources. The location receiver may be configured to receive signals from one or more pseudo satellites and use the signals to determine the location. The earpiece may be configured to receive signals from one or more terrestrial or ground-based transmitters and use the signals to determine the location. The ear piece may further include an inertial sensor disposed within the earpiece housing.
