Abstract: Systems, methods, and computer-readable media are disclosed for dynamic selection of a primary wireless earbud device. In one embodiment, an example system may include a first wireless earbud device having first memory and at least one first processor configured to access the first memory. The at least one first processor may execute computer-executable instructions to determine a first RSSI value for a first connection to a device, determine a first packet error rate value for the first connection, and determine a first link quality score using the first RSSI value and the first packet error rate value. The at least one first processor may execute computer-executable instructions to determine that the first link quality score is less than or equal to a handover threshold, disconnect from the device, and cause a second wireless earbud device to establish a second connection to the device.

Abstract: Technologies directed to a process of establishing a wireless connection between two devices with out-of-band transport assistance are described herein. In one method, a first device scans for a first message via a first radio. The first message includes information that a second device is using either a first or a second set of frequencies of a page hopping sequence. The first device repeatedly sends, via a second radio, a second message according to only the first or second set specified in the first message. The first device receives, via the second radio at a first frequency of the first or second set, a third message from the second device, via the second radio at the first frequency, a third message comprising additional information that establishes the wireless connection between the first device and the second device via the second radio.

Abstract: A system and method includes a first device (e.g., a primary wireless earbud) and a second device (e.g., a secondary wireless earbud). The first device receives audio data from a third device (e.g., a mobile device) and sends the audio data to the second device; the first and second devices output the audio. When the first device detects a wakeword, to reduce use of wireless bandwidth, the first device sends only an indication of duration of playback of the audio data to the second device instead of the audio data. The second device outputs blank audio having a duration corresponding to the received location to stay in sync with the first device. The first device transmits audio data corresponding to the wakeword to the third device.

Abstract: A system and method includes a first device (e.g., a primary wireless earbud) connected to a second device (e.g., a secondary wireless earbud) using a first wireless connection. The first device is also connected to a third device (e.g., a smartphone or smart watch) using a second wireless connection. If the second device determines that the first wireless connection has disconnected, and if re-connection data is not received from the first device, the second device and the third device establish a third wireless connection between them.

Abstract: A system and method includes a first device (e.g., a primary wireless earbud) connected to a second device (e.g., a secondary wireless earbud) using a first wireless connection. The first device is also connected to a third device (e.g., a smartphone or smart watch) using a second wireless connection. If the first device determines that a handoff-triggering event has occurred, the first device disconnects the second wireless connection and the second device and the third device establish a third wireless connection between them.
