Abstract
Wireless earphone systems provide earphones configured to be supported entirely by the ear canals of the wearer and to provide stereophonic reproduction of sound to the wearer based on a two-channel stereophonic signal from a transceiver that is attachable to a device. Certain systems include earphones configured such that channel reception can be switched between the earphones. Certain systems include an earphone that includes: a housing; a ground plane comprising circuitry; and a multi-segmented antenna configured to receive a signal from a transceiver, wherein the antenna and the ground plane are disposed within the housing, wherein the antenna is substantially parallel to the ground plane, and wherein the antenna and the ground plane are separated by a distance.
