Embodiments of wireless audio systems and methods for operation mode switch of wireless headphones 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; transmit, to a second wireless headphone, link information associated with the first short-range wireless link; and remove the first short-range wireless link with the audio source in response to the second wireless headphone successfully establishing a second short-range wireless link with the audio source based on the link information. The second wireless headphone is configured to receive, from the first wireless headphone, the link information associated with the first short-range wireless link; and establish the second short-range wireless link with the audio source based on the link information.

Operation mode switch of wireless headphones

Embodiments of wireless audio systems, wireless transceivers, and methods for wirelessly communicating audio information are disclosed herein. In one example, a wireless audio system includes a primary wireless transceiver and a secondary wireless transceiver. The primary wireless transceiver includes a first radio frequency (RF) module configured to transmit, audio information at a first frequency. The primary wireless audio transceiver further includes a second RF module configured to transmit the audio information at a second frequency. The secondary wireless audio transceiver includes a third RF module configured to receive, the audio information at the first frequency. The secondary wireless transceiver further includes a fourth RF module configured to receive the audio information at the second frequency. At least one of the primary wireless audio transceiver or the secondary wireless audio transceiver includes a control module configured to determine a criterion corresponding to switching a transmission frequency from the first frequency to the second frequency is met. The control model is further configured to switch the transmission frequency.

Wireless audio transceivers

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.
