Claims

1. A headphone comprising:
a wireless transceiver;
an electrical connector;
an earpiece having a speaker, wherein the speaker is controllably connected to the electrical connector and the wireless transceiver;
a data buffer operatively coupled to the speaker and configured to output audio data stored in the data buffer to the speaker; and
control circuitry coupled to the data buffer, the control circuitry configured to:
(i) transition from storing audio data received by the wireless transceiver in the data buffer to storing audio data received by the electrical connector in the data buffer in response to the control circuitry determining the audio data received by the wireless transceiver is being received from the same user device as the audio data received by the electrical connector; and
(ii) continue to store audio data received by the wireless transceiver in the data buffer in response to the control circuitry determining the audio data being received by the wireless transceiver is being received from a different user device than the audio data being received by the electrical connector.
2. The headphone of claim 1, wherein the electrical connector comprises:
a first contact configured to receive electrical power; and
a second contact configured to receive the audio data associated with the second path.
3. The headphone of claim 2, further comprising:
an energy storage device in electrical communication with the first contact and configured to be charged by way of power provided by way of the first contact.
4. The headphone of claim 1, wherein the control circuitry comprises a processor.
5. The headphone of claim 4, wherein the processor is configured to seamlessly transition speaker control between audio data received via the wireless transceiver and audio data received via the electrical connector.
6. The headphone of claim 3, wherein the data buffer is sized to operate the headphone for a predetermined amount of time without the receipt of additional data via the wireless transceiver or the electrical connector.
7. The headphone of claim 1, wherein the headphone is configured to receive digital audio data via the electrical connector.
8. The headphone of claim 3, wherein the energy storage device comprises a rechargeable battery.
9. A method of seamlessly transitioning between data sources controlling operation of a speaker in a headphone, the method comprising:
receiving data at the headphone via a wireless data path;
storing the data received via the wireless data path within a data buffer;
controlling a speaker according to the data stored within the data buffer;
receiving data at the headphone via a wired data path and the wireless data path;
determining whether that the data received via the wireless data path and the wired data path are both being received from the same user device or two different user devices; and
transitioning from storing data from the wireless data path within the data buffer to storing data from the wired data path within the data buffer in response to determining the data received via the wireless data path and the wired data path are received from the same user device; and
continuing to store data received via the wireless data path in the data buffer in response to the control circuitry determining the data being received by the wireless transceiver is being received from a different user device than the data being received from the second path.
10. The method of claim 9, further comprising determining that the data received via the wired data path is the same as the data received via the wireless data path.
11. The method of claim 10, further comprising stopping the storing of data received from the wireless data path within the data buffer.
12. The method of claim 11, comprising identifying a stopping point in the data stored in the data buffer and received from the wireless data path, wherein the stopping point is the last data received from the wireless data path and stored in the data buffer.
13. The method of claim 12, comprising identifying data corresponding to the stopping point in the data received from the wired data path.
14. The method of claim 13, comprising storing data from the wired data path after the data corresponding to the stopping point in the data buffer.
15. The method of claim 9, comprising sizing the data buffer to allow transitioning from storing data from the wireless data path within the data buffer to storing data from the second data path within the data duffer without affecting the controlling of the speaker according to the data stored within the data buffer.
16. The headphone of claim 1, wherein the electrical connector is configured to receive a single plug that delivers both power and data to the headphone.
17. The headphone of claim 1, wherein the controller transitions from storing audio data from the first path to storing audio data from the second path whenever audio data is available from the second path.
18. A headphone comprising:
a wireless transceiver;
an electrical connector;
an earpiece having a speaker, wherein the speaker is controllably connected to the electrical connector and the wireless transceiver;
a data buffer operatively coupled to the speaker and configured to output audio data stored in the data buffer to the speaker; and
control circuitry coupled to the data buffer, the control circuitry configured to:
(i) transition from storing audio data received by the wireless transceiver in the data buffer to storing audio data received by the electrical connector in the data buffer in response to determining the audio data being received by the wireless transceiver is being received from the same user device as the audio data being received by the electrical connector or in response to determining the audio data being received by the wireless transceiver is the same as the audio data being received by the electrical connector; and
(ii) continue to store the audio data from the wireless transceiver when the audio data received by the wireless transceiver is received from a different user device than the audio data received by the electrical connector or when the audio data received by the wireless transceiver is different than the audio data received by the electrical connector.
19. The headphone of claim 18, wherein the electrical connector comprises:
a first contact configured to receive electrical power; and
a second contact configured to receive the audio data associated with the second path.
20. The headphone of claim 18, wherein the audio data being received from the electrical connector has a higher quality than the audio data being received from the wireless transceiver.
