Apple has just released a new firmware update for AirPods Pro 3, build 8B40, on April 30, 2026. The update is notable for its lack of detailed release notes, suggesting it primarily focuses on bug fixes and performance tweaks.
The previous firmware version was 8B39, which launched last month. Users can expect improvements in functionality, although the specific changes remain unclear. AppleInsider reported that the update contains “miscellaneous minor bug fixes.” However, Apple is being rather tight-lipped about what the update brings to the table.
The installation process is straightforward. The firmware updates automatically when the AirPods are in their charging case and the case is plugged into a charger. The linked iPhone must also be in close proximity and connected to Wi-Fi for the update to occur.
This update is currently available only for AirPods Pro 3. There is a possibility that similar updates may roll out for AirPods Pro 2 and AirPods 4 soon. Users can check the installed firmware revision in the settings menu of their device.
The exact details of the improvements in this latest update are not confirmed, leaving some users curious about what enhancements they might experience.
