An earpiece. The earpiece includes an electronics module for wirelessly receiving incoming audio signals from an external source. The earpiece further includes a positioning and retaining structure comprising at least an outer leg and an inner leg, each of the outer leg and inner leg being attached at an attachment end to the body and attached at a joined end to each other. The outer leg lies in a plane. The positioning and retaining structure is substantially stiffer in one direction than in another. In its intended position, one of the two legs contacts the anti-helix at the rear of the concha, the joined end is under the anti-helix; a planar portion of the body contacts the concha; and a portion of the body is under the anti-tragus.

1. An earphone, comprising: an acoustic driver that transduces applied audio signals to acoustic energy;a housing containing the acoustic driver, the housing including a front chamber acoustically coupled to the acoustic driver and a nozzle acoustically coupled to the front chamber;an ear interface comprising a unitary structure having a body and a positioning and retaining structure, the body being configured to fit within the concha of a user's ear, and further including an outlet dimensioned and arranged to fit inside the user's ear canal entrance, the outlet being coupled to the nozzle of the housing and providing a passageway for conducting acoustic energy from the acoustic driver to the user's ear canal;the positioning and retaining structure including a member extending from the body and configured to rest against and apply outward pressure to the antihelix of the user's ear to retain the earphone in the user's outer ear. 2. The earphone of claim 1, further comprising a cable electrically coupled to an input of the acoustic driver and configured to mechanically and electronically couple the earpiece to another device. 3. The earphone of claim 1, further comprising an electronics module for wirelessly receiving incoming audio signals from an external source, the electronics module comprising a microphone for transducing sound into outgoing audio signals,the electronics module further comprising circuitry for wirelessly transmitting the outgoing audio signals. 4. The earphone of claim 3 wherein the member comprises at least an outer leg and an inner leg, each of the outer leg and inner leg being attached at an attachment end to the body and attached at a joined end to each other; wherein the outer leg lies in a plane and wherein the positioning and retaining structure is substantially stiffer when force is applied to the end in one rotational direction in the plane of the outer leg than when it applied in the opposite rotational direction in the plane of the outer leg. 5. The earphone of claim 3, wherein the plane of the positioning and retaining structure member is not parallel to or coplanar with a plane where the body is in contact with the concha. 6. The earphone of claim 4, wherein, when the earphone is inserted into the ear and the body is rotated in a clockwise direction, one of the joined end contacting the base of the helix orthe joined end becoming wedged in the cymba concha region of the anti-helix, orthe inner leg contacting the base of the helixprevents further clockwise rotation. 7. The earphone of claim 3, wherein, when the earphone is in position, a reaction force is exerted that urges the positioning and retaining structure member against the anti-helix at the rear of the concha. 8. The earphone of claim 3, wherein the body further comprises an inner section, and wherein the inner section comprises a harder material than the outlet section. 9. The earphone of claim 8, wherein the outlet section comprises a material of hardness of about 16 Shore A and the inner section comprises a material of about 70 shore A. 10. The earphone of claim 3, wherein the nozzle is characterized by an outer diameter measured in a direction;wherein the outlet section is characterized by a diameter measured in the direction;and wherein the outer diameter of the nozzle is less than the inner diameter of the outlet section. 11. The earphone of claim 10, wherein the outlet section and the nozzle are generally oval, and wherein the minor axis of the outlet section is about 4.80 mm and the minor axis of the nozzle is about 4.05 mm. 12. The earphone of claim 3, wherein the audio module is oriented so that a portion of the audio module is in the concha of the ear of a user when the earpiece is in position. 13. The earphone of claim 4, wherein the stiffness when force is applied in a direction perpendicular to the plane is less than 0.01 N/mm. 14. The earphone of claim 4, wherein the stiffness when force is applied in a direction perpendicular to the plane of the outer leg is less than the stiffness when force is applied in either the clockwise or counterclockwise directions in the plane of the outer leg. 15. The earphone of claim 14, wherein the stiffness when force is applied in a direction perpendicular to the plane of the outer leg is less than 0.8 times the stiffness when force is applied in either the clockwise or counterclockwise directions in the plane of the outer leg. 16. The earphone of claim 14, wherein the stiffness when force is applied in a direction perpendicular to the plane of the outer leg is less than 0.01 N/mm. 17. The earphone of claim 4 wherein when the earphone is in its intended position in the user's ear, the outer leg rests against the anti-helix;the joined end is under the anti-helix;a planar portion of the body contacts the concha; anda portion of the body is under the anti-tragus of the user's ear.
