Abstract
Embodiments of wireless audio systems and methods for wirelessly communicating audio information are disclosed herein. In one example, a wireless audio system includes a first wireless headphone and a second wireless headphone. The first wireless headphone is configured to establish a first short-range wireless link with an audio source and a second short-range wireless link with a second wireless headphone; transmit, to the audio source over the first short-range wireless link, a first global acknowledgement (ACK) message indicative of whether the first wireless headphone and the second wireless headphone successfully receive audio information transmitted by the audio source; in response to a mode switch event, transmit, to the second wireless headphone over the second short-range wireless link, status information associated with the first short-range wireless link; in response to the second wireless headphone successfully receiving the status information, transmit, to the second wireless headphone over the second short-range wireless link, a switch start message to switch modes of the first and second wireless headphones; and after transmitting the switch start message, transmit, to the second wireless headphone over the second short-range wireless link, a first local ACK message indicative of whether the first wireless headphone successfully snoops the audio information. The second wireless headphone configured to establish a third short-range wireless link with the audio source based on link information associated with the first short-range wireless link for snooping the audio information transmitted over the first short-range wireless link; receive, from the first wireless headphone over the second short-range wireless link, the status information; receive, from the first wireless headphone over the second short-range wireless link, the switch start message; after receiving the switch start message, receive, from the first wireless headphone over the second short-range wireless link, the first local ACK message; and transmit, to the audio source over the third short-range wireless link based on the status information, a second global ACK message indicative of whether the first wireless headphone and the second wireless headphone successfully receive the audio information based on the first local ACK message.
