Just on a sidenote, sometimes it is _not_ automatic. Sometimes you have to close the battery case and then re-open multiple times to find the update, which it will appear at times and other times it will disappear. Its happened to multiple members, which I believe there is a thread somewhere reference this occurrence.Latest AirPod update is 3.7.2. Once paired and connected to an iPhone, you can view info by going to Settings>General>About>AirPods. If there is a new update, iOS will automatically update the firmware.
