Hilmar Lehnert

Abstract

Examples described herein relate to a charging system for wireless earbuds involving charging adapters that are attachable to the wireless earbuds. In some implementations, the charging adapter is attachable to an external surface of an earbud using a magnetic or mechanical interface that align electrodes of the charging adapter with electrodes on the wireless headset, allowing an internal battery of the earbud to draw current and charge from the charging adapter while the earbud is in-ear. Then, when the internal battery is and recharged using a charging case or wall charger, the charging adapter can be detached from the earbud.
