Abstract (en)
[origin: WO2020117404A1] A system and method includes a first audio-output device (e.g., a primary wireless in-ear device) connected to a second audio-output device (e.g., a secondary wireless in-ear device) using a first wireless connection. The first audio-output device is also connected to a third device (e.g., a smartphone or smart watch) using a second wireless connection. When the first and second audio-output devices exchange roles as primary and secondary, they first disconnect the second wireless connection and establish a third wireless connection between the second device and the third device. The first audio-output device sends packets stored thereon to the second audio-output device; the second audio-output device outputs audio corresponding to these packets before outputting audio corresponding to packets received from the third device.
