AirPods 4A402 Firmware Bugs

Do you notice any issues fixed by this release? Any new problems found in this version will be also updated here. Thanks, in advance, for your contribution!

Known Issues

  • Notify When Left Behind not working properly. The feature triggers erroneous alerts when AirPods are in the user’s pocket.
  • Airpods audio cutting out and unexpectedly disconnecting from Mac. (Unclear if this is AirPods related or a macOS Monterey issue.)
  • AirPods Case battery draining faster than usual.
  • AirPods Pro auto pairing not working properly. It takes a long time for audio to start playing although earbuds are connected.
  • AirPods Pro won’t auto pair with non-Apple devices (older Macs either). Setting them to pair ‘When Last Connected’, doesn’t prevent them to automatically pair to the first iPhone available in the devices list.

New Bugs

  • To be updated. (Hopefully not.)
