Apple has released new firmware for multiple AirPods models that turns on a set of features tied to its upcoming operating system releases. The update carries the build number 9A348 and is available for the AirPods Pro 2, AirPods Pro 3, AirPods 4, and AirPods Max 2.

What the new firmware enables

The firmware is designed to work alongside iOS 27, iPadOS 27, and macOS Golden Gate. Once installed, it activates a redesigned AirPods interface along with several new controls and capabilities.

According to Apple, the additions include:

  • A new AirPods interface across iPhone, iPad, and Mac
  • A slider for Adaptive mode, giving users finer control over how much outside noise passes through
  • Support for custom EQ, allowing personalized audio tuning
  • Compatibility with the new Siri AI

These changes are aimed at giving AirPods owners more granular control over sound and noise management, while extending Apple's revamped Siri experience to its earbuds and headphones.

How to install the update

Unlike iPhones or Macs, AirPods do not have a manual software update button, which means the process happens quietly in the background. To receive the firmware, users need to connect their AirPods to an Apple device and place them on power.

Apple notes that installation is not instant. It can take a few hours for the new firmware to fully apply, so owners may not see the changes immediately after connecting their earbuds.

Why it matters

Firmware updates for AirPods are often overlooked, but they are the mechanism Apple uses to deliver meaningful new functionality to hardware people already own. In this case, existing AirPods buyers gain features like custom EQ and a more flexible Adaptive mode without needing to purchase new hardware, provided they are running the latest software on their paired devices.

The tie-in with the new Siri AI is particularly notable, as it positions AirPods as an entry point to Apple's expanded assistant capabilities. Users who want to take advantage of the additions will need both the updated firmware and iOS 27, iPadOS 27, or macOS Golden Gate installed on their connected devices.
