Abstract
A system and method includes a first device (e.g., a primary wireless earbud) and a second device (e.g., a secondary wireless earbud). The first device receives audio data from a third device (e.g., a mobile device) and sends the audio data to the second device; the first and second devices output the audio. When the first device detects a wakeword, to reduce use of wireless bandwidth, the first device sends only an indication of duration of playback of the audio data to the second device instead of the audio data. The second device outputs blank audio having a duration corresponding to the received location to stay in sync with the first device. The first device transmits audio data corresponding to the wakeword to the third device.
