Abstract
The present disclosure provides for power conservation in truly wireless earbuds or other paired wireless devices, by switching a secondary device into a power save mode when the devices are not receiving traffic from the host. In this power-save mode the devices are put into a lower duty cycle than conventional configuration. The primary and secondary devices communicate over a backchannel communication link at a very low duty cycle, in some examples below lower bounds specified for standard communication with other devices. The primary earbud may be responsible for letting the secondary earbud know when to leave power-save mode and resume regular operation.
