Audio class-compliant charging accessories for wireless headphones and headsets

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;
• determining that the data received over the wireless data path and the wired data path are both being received from the same user device;
• and
• transitioning from storing data from the wireless data path within the data buffer to storing data from the second data path within the data buffer.

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) provide a first path for audio data received by the wireless transceiver to be stored in the data buffer and a second path for audio data received by the electrical connector to be stored in the data buffer,
• (ii) determine that the audio data being received from the first path and the second path are the same, and
• (iii) transition from storing the audio data from the first path in the data buffer to storing the audio data from the second path.
