A first device is configured to establish a connection over a short-range communication link with a second device. The first device may transition to a sleep state, terminate (i) a paging operation and a page scanning operation associated with a paging protocol and (ii) an advertisement scanning operation associated with an advertisement protocol and perform an advertisement broadcast operation associated with the advertisement protocol, the advertisement broadcast operation generating an advertisement to be broadcast at a first interval, wherein the first interval is greater than a second interval for performing advertisement broadcast operations in an active state.

Low-power activation of accessory in sleep state

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.

Communication between a case and an earbud with reduced power consumption

Systems, methods, and non-transitory computer-readable storage media for determining when to wirelessly communicatively couple together a pair of untethered wireless audio output devices and for determining when to erase a connection history stored on one or both of the wireless audio output devices.

Wireless audio output devices

A case for a pair of earbuds includes a housing having cavities to receive the pair of earbuds and charging circuitry that is configured to initiate charging of the pair of earbuds when an earbud detector detects that the earbuds are inserted within the cavities.

Earbud case with charging system

A case for a pair of wireless earbuds includes a lid and a lid sensor configured to generate a detect signal when the lid is moved from a closed position to an open position. The case further includes circuitry configured to, in response to receiving the detect signal, send a signal to the wireless earbuds to turn them on and to initiate a pairing sequence between the wireless earbuds and an electronic device.

Wireless pairing of earbuds and case

A case for a portable listening device includes a lid and a lid sensor to detect if the lid is in an open or a closed position. The case further includes circuitry configured to turn on a wireless radio within the portable listening device when the lid sensor detects the lid is moved from the closed position to the open position.
