AirPods Custom EQ in iOS 27: How to Adjust Bass, Mids, and Treble
After years of relying on Adaptive EQ and presets, Apple has finally given AirPods users direct control over their sound. iOS 27 introduces a built-in Custom Equalizer for compatible AirPods, letting you adjust bass, mids, and treble to match your personal listening preferences.
Unlike Apple Music’s EQ presets—which only affect music playback—the AirPods Custom EQ applies across your entire listening experience, including podcasts, movies, calls, and system audio.
Which AirPods Models Support Custom EQ?
Custom EQ is available on AirPods models powered by Apple’s H2 audio chip, including:
| ✅ Supported Models | ❌ Not Supported |
|---|---|
| AirPods Pro 3 | Original AirPods Max |
| AirPods Pro 2 | Earlier AirPods models |
| AirPods Max 2 | AirPods 1st/2nd generation |
| AirPods 4 |
You’ll also need iOS 27, iPadOS 27, or macOS 27 running on your connected device.
How to Enable Custom EQ for AirPods
Step 1: Update Your AirPods Firmware (If Needed)
If you don’t see the Equalizer option, your AirPods may need a firmware update:
-
Connect your AirPods to your iPhone.
-
Place them inside their charging case and connect the case to power.
-
Wait 20–30 minutes while the firmware installs automatically in the background.
Step 2: Access the Equalizer Settings
-
Open Settings on your iPhone.
-
Tap your AirPods name at the top of the screen.
-
Select Audio & Routing.
-
Tap Equalizer.
Step 3: Customize Your Sound
-
Select Custom to unlock the manual three-band EQ.
-
Adjust the three frequency sliders:
-
Low (Bass) – deep tones, beats, and low-end punch
-
Mid – vocals, guitars, and most instruments
-
High (Treble) – cymbals, hi-hats, and bright details
-
-
Play music while adjusting—changes take effect in real time.
Tip: Start with small adjustments and listen carefully. A little goes a long way.
How to Reset the EQ
If you’re not happy with your adjustments:
-
Open Settings → your AirPods → Audio & Routing → Equalizer.
-
Select Recommended.
This restores Apple’s default sound profile.
What If Custom EQ Is Missing?
If you can’t find the Equalizer option, try these fixes:
-
Update your AirPods to the latest firmware.
-
Reconnect your AirPods (forget device, then re-pair).
-
Restart your iPhone.
-
Verify your AirPods model supports the feature (H2 chip required).
FAQs
Does Custom EQ work in every app?
Yes. Apple designed the new AirPods Custom EQ to affect audio played through your AirPods across all supported content—not just Apple Music.
Can I adjust bass only?
Yes. You can increase or decrease the Low frequency control without changing the Mid or High settings.
Will this replace Adaptive EQ?
No. Adaptive EQ still works behind the scenes where supported, while Custom EQ lets you personalize the overall sound profile.
Can I save multiple EQ presets?
At launch, Apple does not provide multiple preset profiles that you can save and switch between. Only one Custom setting is available at a time.
Does Custom EQ work with older AirPods?
No. The feature requires the H2 audio chip, found in AirPods Pro 3, AirPods Pro 2, AirPods Max 2, and AirPods 4.
