Apple introduced a new software version for AirPods models with the iOS 27 update. The prominent innovation of the new AirPods software is the special equalizer settings that users have been requesting for a long time. On supported AirPods models, bass, mid and treble frequencies can now be changed separately directly via the Settings application. In this way, users who do not prefer Apple’s default sound character can make the headphone’s output closer to their own listening habits. Although the system does not offer as comprehensive options as advanced multi-band equalizers, it provides one of the basic sound customization options that has been missing on the AirPods side so far.
The new AirPods software uses build number 9A350 for AirPods 5 and 9A348 for other supported models. The source states that the update is available for AirPods Pro 3, AirPods 5, AirPods 5 with wireless charging box, AirPods Pro 2 with Lightning and USB-C connection, and AirPods Max 2 models. Due to Apple’s current update system, users do not need to download and install the software manually. The new firmware is automatically installed when the AirPods are charging and within Bluetooth range of a Wi-Fi-connected iPhone, iPad or Mac. Users can check which software version their headphones have via the Settings app on iPhone.
How do AirPods custom equalizer settings work?
After the new software is installed, the custom equalizer option appears in the AirPods settings. The section under the Sound and Routing menu in the Settings application allows you to change low, medium and high frequencies via separate controls. Apple states that AirPods are designed to transmit music, TV series and movie content, as well as the sound in calls, as faithfully as possible. However, for users who prefer a different sound profile, these base frequency settings can now be changed at the system level. The ability to play a track via Apple Music during adjustment makes it easy to listen to the effects of the changes in real time.
The solution offered by Apple remains quite basic with its three-band structure. There are no detailed frequency curves, ready-made profiles or multiband controls seen in professional music applications or companion applications of some rival headphones. Despite this, the new option may be sufficient for daily use, especially for users who want more pronounced bass, highlighted vocals or brighter trebles. Those who are satisfied with the default sound setting do not need to make any changes. The advantage of the custom equalizer is that it can change the basic sound character within the AirPods settings without directing users to different third-party applications.
With iOS 27, the general structure of AirPods settings has also been rearranged. Apple is changing the AirPods interface in the Settings app, gathering Hearing Health, Find My, Live Translate and other functions under separate menus. Thanks to the new slider added to the Adaptive Sound feature, the behavior of this mode can be adjusted in more detail than in previous versions. In addition, GymKit support, which has required an Apple Watch for years, can also be used on iPhone and AirPods Pro 3 with iOS 27. While AirPods Pro 3 users can benefit from the Precision Find feature via the Find My app on Apple Watch, interaction with Siri’s new artificial intelligence features is also supported on AirPods models paired with a compatible iPhone.
It is stated that the special equalizer feature is offered for AirPods models with H2 chip, and the source lists AirPods Pro 2, AirPods Pro 3, AirPods 4 and AirPods Max 2 in this context. Since this information does not fully correspond to the supported model list in the previous section of the source text, it would be best to check the model-based support status from the device’s Settings menu during the distribution of the update. Still, the core aspect of the software clearly focuses on audio customization. For the first time, Apple provides the user with a direct and easily accessible control area over the AirPods sound character, which has been kept more closed for a long time. Although the three-band structure is limited, the ability of AirPods users to change the basic frequency balance without the need for an additional application stands out as one of the most useful innovations of the update.
