Wireless earphones and earphones charging case
Rechargeable wireless earphone systems and charging cases are disclosed. The rechargeable charging case, which doubles as a storage case for the earphone components, includes externally accessible charging ports adapted to charge the rechargeable battery contained therein as well as for charging other electronic devices. The earphones are configured such that they may be used even when charging or when the earphone system battery is depleted. An alignment and positioning mechanism is provided to align and electrically connect charging contacts of a controller housing of the earphone system with charging contacts provided in the charging case to better secure and facilitate the charging process when the controller is received within the charging case. Reversibly detachable ear hooks and ear canal plugs are uniquely designed and configured to be independently attached to the earphone housing and compliantly adjustable to the desired shape for user comfort. The ear hooks and plugs may be configured such that the ear hooks at least partially encircle the ear plugs when both are attached to the earphone housing and either the ear hooks and/or ear plugs may be detachable from the earphone without removal of the other. Illuminated ear hooks and cable are also disclosed.

8. The assembly of claim 5 , wherein the right and left earphones are configured to play audio from an audio signal received through the cable adapter when the one or more rechargeable batteries are depleted.
9. The assembly of claim 1 , wherein the charging case further comprises a charging port that is configured to allow power out of the charging case to facilitate charging an external electronic device.
10. The assembly of claim 9 , wherein the charging port is a USB output port.
11. The assembly of claim 1 , further comprising a first sleeve configured to receive the first cable and a second sleeve configured to receive the second cable, wherein the first sleeve is located at an end region of the right earphone and the second sleeve is located at an end region of the left earphone.
12. The assembly of claim 11 , wherein the first sleeve and the second sleeve are made of thermoplastic polyurethane.
13. The assembly of claim 1 , wherein the right earphone has a light source that transmits light to an ear hook attached to the right earphone through a light conducting material housed in a light pipe in the ear hook.
14. The assembly of claim 13 , wherein the light source is an LED or a laser.
15. The assembly of claim 1 , wherein the assembly includes at least one ear hook that includes an ear hook housing and a wire core element positioned therein.
16. The assembly of claim 15 , wherein the wire core element extends longitudinally within the ear hook and is positioned nearer to one side of the ear hook housing than the other side.
17. The assembly of claim 16 , wherein the ear hook is configured to include a proximate edge that is configured to reside near the base of the user's outer ear and a distal edge that is configured to reside further away from the base of the user's outer ear, and wherein the wire core element is housed nearer the distal edge as compared to the proximate edge in one or more regions of the ear hook housing.
18. The assembly of claim 5 , wherein the direct line-in connection is provided when said one or more rechargeable batteries is depleted.
19. The assembly of claim 5 , wherein the direct line-in connection is provided when said one or more rechargeable batteries have a battery level that is lower than a predetermined critical point.
