iOS 27 brings custom equalizer to AirPods with H2 chip
Apple's iOS 27 beta introduces a custom EQ feature for AirPods, allowing users to adjust frequencies like bass and vocals. The feature works with AirPods models equipped with the H2 chip, including AirPods Pro 2, Pro 3, AirPods 4, and AirPods Max 2. Users can access it via Settings > Audio & Routing > Equalizer, and need beta firmware on both device and AirPods.
The custom equalizer arrives through Apple's beta software pipeline, requiring both the host device and the AirPods themselves to run pre-release firmware. Users activate the feature by toggling AirPods Beta Updates in Settings before the Equalizer submenu appears under Audio & Routing. Firmware transfers automatically when the earbuds rest in their charging case near the paired iPhone, iPad, or Mac.
Apple's implementation uses a three-band design covering lows, mids, and highs rather than a more granular multi-band system. The default "Recommended" profile varies by hardware — the AirPods Pro 3 delivers deeper bass thanks to its in-ear seal, while the open-design AirPods 4 lacks that isolation. A reset button restores default settings if adjustments go wrong.
This feature could make audio personalization more accessible to everyday listeners who might otherwise avoid complex EQ interfaces. Casual music fans may find it easier to tailor sound to their tastes, potentially reducing reliance on third-party apps. Audiophiles might view the three-band approach as limited, but the simplicity could broaden adoption of sound customization among mainstream
