Apple updates third-generation AirPods firmware to version 4C170
Apple has pushed a new firmware version to owners of the third-generation AirPods, though it is not known what new features or bug fixes the updates include.
Today’s update pushes the AirPods 3 firmware up version from 4C165 which was released in December, but unlike the December update, today’s firmware release is only for the latest generation AirPods and not the rest of the AirPods wireless audio lineup.
Firmware updates begin installing automatically over-the-air while the AirPods are connected to an iOS device.
To check whether your AirPods have been upgraded to the latest firmware version, make sure the AirPods are connected to your iOS device and open the Settings app. Tap General → About then tap AirPods. Here you will see the firmware version your AirPods are currently using.
