The AirPods Pro got their new firmware update last week. Now that same firmware version is rolling out to the second generation of the original AirPods.

To check your firmware, go to:

Settings > General > About > (Your AirPods)

Interestingly, my second gen AirPods grabbed that since-pulled 2C54 firmware update and have still not updated. No clue how long they’ll be stuck on 2C54 and there’s no way to force an update.
