Apple Rolls Out AirPods Beta Firmware 9B5045a; Battery Replacement Costs Clarified

Firmware Update Details

Apple has officially released a new beta firmware version, designated as build 9B5045a, for its lineup of wireless headphones. This update is currently available to developers and public beta testers. The firmware applies to a wide range of current and recent AirPods models, including the AirPods Pro 2, AirPods Pro 3, AirPods 4, AirPods 5, and the AirPods Max 2. The release marks a routine step in Apple’s software development cycle, allowing early adopters to test potential improvements before a public rollout.

Installation Requirements and Process

Users interested in installing this beta firmware must ensure their primary Apple device is running iOS 26, iPadOS 26, or macOS 26 or later. The update is not pushed automatically; instead, it must be manually enabled within the AirPods settings interface on the connected device. Once the beta update toggle is activated, the firmware can be downloaded by connecting the AirPods to an Apple device and ensuring they are connected to a power source.

The installation process differs significantly from standard software updates on iPhones or iPads. There is no dedicated software update screen for the headphones themselves. Instead, the firmware installs in the background while the AirPods are charging. Apple notes that this process can take several hours to complete, as the headphones must remain connected and powered throughout the duration. Users are advised not to disconnect the devices until the installation is confirmed.

Undisclosed Changes

As is standard practice for AirPods firmware releases, Apple has not provided release notes or a changelog for build 9B5045a. Consequently, the specific improvements, bug fixes, or new features included in this update remain unknown. Historically, AirPods firmware updates often address connectivity issues, microphone quality, or battery management algorithms, but without official documentation, these assumptions cannot be confirmed for this specific build.

Battery Replacement Program

In a related development regarding hardware longevity, Apple continues to promote its battery replacement service for aging AirPods. Rather than repairing individual units by opening the casing, Apple’s policy involves recycling the old device and providing a replacement unit. This service is designed to extend the usable life of the headphones without requiring a full retail purchase.

The cost for this service is standardized based on the model. For most AirPods models, including the standard AirPods and AirPods Pro variants, the battery replacement fee is $49 per earbud. This totals $98 if both earbuds require replacement. For the premium AirPods Max, the fee is higher at $79 per unit. These costs are significantly lower than the retail price of new models, such as the AirPods Pro, which typically cost $249.

Market Implications

This battery replacement option provides a viable alternative for consumers whose devices have degraded over time. With the average lifespan of wireless earbuds often shorter than the initial purchase cycle, many users face the decision of repairing or replacing. The relatively low cost of the battery service makes it an attractive option for maintaining audio quality without the environmental impact and financial burden of buying new hardware. Apple’s approach encourages recycling while keeping customers within its ecosystem.
