Audio synchronization during handover

An apparatus for wireless communications at a first wireless audio device, comprising:

• a processor,
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• identify, based at least in part on communicating with a second wireless audio device, a link quality between the second wireless audio device and a host device;
• initiate, based at least in part on the identified link quality, a handover interval comprising one or more extended synchronous connection-oriented (eSCO) windows;
• buffer a set of one or more audio data packets during the handover interval based at least in part on the initiating;
• discard at least a first portion of the set of one or more audio data packets during the handover interval based at least in part on determining that the first portion of the set of one or more audio data packets has been transmitted to the host device by the second wireless audio device;
• receive, during an extended retransmission portion of a first eSCO window of the handover interval, a handover indication from the second wireless audio device;
• and
• transmit, to the host device based at least in part on the handover indication, at least a second portion of the set of one or more audio data packets during a second eSCO window that is subsequent to the handover interval.

A non-transitory computer-readable medium storing code for wireless communications at a first wireless audio device, the code comprising instructions executable by a processor to:

• identify, based at least in part on communicating with a second wireless audio device, a link quality between the second wireless audio device and a host device;
• initiate, based at least in part on the identified link quality, a handover interval comprising one or more extended synchronous connection-oriented (eSCO) windows;
• buffer a set of one or more audio data packets during the handover interval based at least in part on the initiating;
• discard at least a first portion of the set of one or more audio data packets during the handover interval based at least in part on determining that the first portion of the set of one or more audio data packets has been transmitted to the host device by the second wireless audio device;
• receive, during an extended retransmission portion of a first eSCO window of the handover interval, a handover indication from the second wireless audio device;
• and
• transmit, to the host device based at least in part on the handover indication, at least a second portion of the set of one or more audio data packets during a second eSCO window that is subsequent to the handover interval.
