Abstract:
1. A wireless earphone system comprising: a transceiver configured to wirelessly transmit a two-channel stereophonic signal; a first earphone comprising a first tip configured to be inserted into a first ear canal of a wearer, wherein the first earphone is configured to receive a first channel of the two-channel stereophonic signal from the transceiver, and wherein the first earphone is configured to be supported entirely by the first ear canal of the wearer when the first tip is inserted into the first ear canal; and a second earphone comprising a second tip configured to be inserted into a second ear canal of the wearer, wherein the second earphone is configured to receive a second channel of the two-channel stereophonic signal from the transceiver, and wherein the second earphone is configured to be supported entirely by the second ear canal of the wearer when the second tip is inserted into the second ear canal, wherein the first earphone and the second earphone together provide stereophonic reproduction of sound to the wearer based on the two-channel stereophonic signal from the transceiver when the tips are inserted into the ear canals of the wearer, and wherein at least one of the first earphone and the second earphone excludes external noise greater than thirty decibels from entering an ear canal of the wearer when the earphone tip is inserted into the ear canal such that the ear canals are substantially acoustically sealed.
