A case can communicate with one or more earbuds to obtain information related to the earbuds, such as a battery charge level of the earbud. Due to the interface circuits within the case and the earbuds, the case can obtain the information from a power management unit of the earbud without first communicating with a processor (serving as the central processing unit) of the earbud. As a result, the processor can be powered down, i.e., inactive, and the case can still communicate with the earbud. Examples in which the processor can be powered down include when the earbud is in the case and not in use/service by a user, or when the earbud battery charge level is relatively low.
