Your AirPods Pro used to drown out the subway or your coworker’s endless phone calls. Now they don’t. That’s annoying, and it’s easy to assume the worst. Did I break them? Probably not. Active Noise Cancellation is fussy about three things: ear tip fit, clean microphones, and having the right listening mode picked. Most fixes here take five minutes.
This guide runs through the likely causes in order, starting with the easy stuff (fit, cleaning) and ending with a factory reset, plus when it’s actually time to call Apple.
Quick Fixes to Try First
Run through these four basics before anything else. They solve most ANC complaints on their own.
- Reseat your AirPods: Take both out and push them back in snugly. A loose seal is the #1 cause of weak noise cancellation, by far.
- Check the noise control mode: Open Control Center and confirm Noise Cancellation is selected, not Transparency, Off, or Adaptive Audio.
- Charge both AirPods: Low battery makes ANC cut out or act inconsistently. Give them 15 minutes in the case.
- Restart your iPhone: This clears minor Bluetooth glitches that mess with how your AirPods talk to your phone.
Still no luck? Work through the detailed issues below; they’re ordered from most to least common.
Symptoms and Fixes
| Symptom | Likely Cause | Quick Fix |
|---|---|---|
| ANC feels weak or “leaky” | Poor ear tip seal | Run the Ear Tip Fit Test / Acoustic Seal Test |
| Muffled sound, more background noise than usual | Blocked microphone mesh or vents | Clean the mics and ear tips |
| Noise Cancellation does nothing when tapped | Wrong mode active (Transparency/Adaptive) | Re-select Noise Cancellation manually |
| ANC stopped after an update | Outdated firmware | Charge near iPhone with Wi-Fi for 30+ minutes |
| ANC cuts in and out | Low battery | Fully charge AirPods and case |
| Mode selector greyed out or unresponsive | Software/connection glitch | Forget device and re-pair |
| Nothing above works | Possible hardware fault | Factory reset, then contact Apple Support |
Common Issues and Solutions
Issue 1: Ear Tips Aren’t Creating a Proper Seal
Symptoms:
- ANC sounds weak, thin, or inconsistent between left and right AirPod
- Bass sounds noticeably reduced
- Outside voices and traffic noise still come through clearly
Why it happens: ANC needs a physical seal in your ear canal to do its job. If the tips are too small, too large, or not pushed in deep enough, sound leaks around the edges. Once that happens, there’s nothing for the noise cancellation to work with, no software fix changes that.
Fix:
On AirPods Pro 1st and 2nd generation, Apple calls this the Ear Tip Fit Test. On AirPods Pro 3 (which shipped with a redesigned tip system), it’s renamed the Acoustic Seal Test. Same idea, same steps.
- Put both AirPods Pro in your ears.
- Open Settings > Bluetooth.
- Tap the ⓘ info icon next to your AirPods Pro in the device list.
- Scroll down and tap Ear Tip Fit Test (Pro 1/2) or Acoustic Seal Test (Pro 3).
- Tap Continue, then tap the Play button to run a short test tone.
- Review the result: Good Seal means you’re set. Adjust AirPods Pro or a size recommendation means reposition them or try a different tip size.
If you get an “Adjust” result, swap in a different ear tip size. AirPods Pro ship with XS, S, M, and L tips, re-run the test right after each change. A lot of people are wearing the wrong size and have no idea, because they never took the pre-installed tip off the box.
Verify: Run the test again after adjusting. You want to see “Good Seal” or “Good Fit” in both ears before moving on.
Tip: Never swapped your ear tips before? Try all four sizes before you decide ANC itself is the problem.
Issue 2: Blocked Microphones or Vents
Symptoms:
- More ambient noise gets through than usual, even with a good seal
- Sound quality seems muffled or bass-heavy
- Issue developed gradually rather than suddenly
Why it happens: AirPods Pro use multiple microphones to sample outside noise and cancel it in real time. Earwax, dust, and pocket lint clog the mesh over those mics and the pressure-equalizing vents. Your seal can be perfect and ANC will still suffer.
Fix:
- Remove your AirPods Pro and inspect the mesh openings on the stem and the speaker mesh that faces your ear canal.
- Using a dry, soft-bristled brush or a clean, dry cotton swab, gently brush away visible debris. Never use water, alcohol, or anything sharp.
- Wipe the ear tips with a lint-free cloth. Silicone tips can be rinsed separately with water, just let them dry completely before reattaching.
- Reattach the tips firmly until they click into place.
Verify: Put your AirPods back in and run the Fit Test / Seal Test again, or just listen in a consistently noisy spot like a running dishwasher or busy street.
Tip: Earwax build-up is the usual culprit here. If you wear AirPods Pro daily, clean mics and tips every couple of weeks so this doesn’t creep up on you.
Issue 3: Wrong Noise Control Mode Selected
Symptoms:
- ANC “stopped working” right after you swear you didn’t change anything
- Outside sound seems to fade in and out on its own
- Works fine in some environments, not others
Why it happens: AirPods Pro have four listening modes, Noise Cancellation, Transparency, Off, and Adaptive Audio (Pro 2 and later). Adaptive Audio automatically blends Transparency and Noise Cancellation based on your surroundings, which can feel like ANC is off when it’s just letting sound through on purpose. It’s easy to bump into a different mode with a stem press, or have an update reset your preference without asking.
Fix:
- With AirPods Pro in your ears and connected, open Control Center on your iPhone (swipe down from the top-right corner on Face ID models).
- Press and hold the volume slider to expand the audio controls.
- Tap Noise Control and select Noise Cancellation explicitly.
Alternatively, check it from Settings:
- Go to Settings > Bluetooth > tap the ⓘ next to AirPods Pro.
- Under Noise Control, confirm Noise Cancellation is selected rather than Transparency, Off, or Adaptive Audio.
Verify: You should hear ambient sound drop immediately once Noise Cancellation is active. Still no difference? Move on to the next issue.
Tip: Want to know exactly how these modes differ and when to use each one? It’s worth reading up on Transparency Mode versus Noise Cancellation before picking a default.
Issue 4: Outdated AirPods Firmware
Symptoms:
- ANC quality changed noticeably after an iOS update
- Firmware version under About hasn’t updated in months
- Other AirPods features (like Adaptive Audio or Conversation Awareness) also seem off
Why it happens: AirPods Pro run their own internal firmware, separate from iOS. Apple periodically ships updates that improve the noise cancellation algorithms and fix bugs, including a beta firmware Apple pushed to AirPods Pro 3 as recently as August 2026. These updates install automatically, but only under the right conditions, so it’s easy for a device to fall behind without you noticing.
Fix:
There’s no download button for this. Instead:
- Place both AirPods Pro in the charging case.
- Connect the case to a charger, or make sure it already has enough charge.
- Keep your paired iPhone, iPad, or Mac nearby, connected to Wi-Fi, for at least 30 minutes.
- Make sure that device is reasonably current: on iPhone/iPad go to Settings > General > Software Update (on Mac, System Settings > General > Software Update) and install pending updates — Apple requires the host device to be on a current OS for firmware delivery to proceed.
Verify: Go back to Settings > Bluetooth > ⓘ next to AirPods Pro, and scroll to About. Compare the firmware version there against Apple’s AirPods firmware support page to confirm you’re current.
Issue 5: Low Battery Causing Inconsistent ANC
Symptoms:
- ANC works fine for a while, then seems to fade or disappear
- Problem is worse later in the day
- One AirPod behaves differently than the other
Why it happens: Noise cancellation is one of the more power-hungry features on AirPods Pro. Apple hasn’t documented an official low-battery ANC throttling feature, but many users notice ANC feels weaker or cuts out as the battery gets low — a pattern consistent with the extra power draw.
Fix:
- Place both AirPods in the case and close the lid for at least 15 minutes.
- Check battery levels by opening the case near your iPhone, or ask Siri: “What’s my AirPods battery level?”
- Once both AirPods and the case show a healthy charge, take them out and confirm Noise Cancellation is still your selected mode. (Charging sometimes resets it to Adaptive Audio, oddly enough.)
Verify: Test ANC in a noisy room after a full charge. If it’s back to normal, low battery was the cause. If long days keep triggering this, just carry the case topped up.
Issue 6: Noise Cancellation Option Does Nothing When Tapped
Symptoms:
- Tapping “Noise Cancellation” in Settings or Control Center has no effect
- Mode selector appears greyed out or unresponsive
- AirPods otherwise connect and play audio normally
Why it happens: This points to a software or Bluetooth connection glitch. Your iPhone thinks it sent the mode-change command, but it never actually reached the AirPods.
Fix:
- Go to Settings > Bluetooth.
- Tap the ⓘ next to your AirPods Pro.
- Tap Forget This Device, then confirm.
- Open the AirPods Pro case near your iPhone with the lid open, wait for the pairing animation, and tap Connect.
Verify: Once re-paired, open Control Center and switch to Noise Cancellation again. It should respond right away, with an audible change in ambient sound.
Issue 7: Factory Reset as a Last Resort
Symptoms:
- ANC issues persist after trying every fix above
- Mode switching, firmware updates, and re-pairing all failed to help
Why it happens: A deeper software glitch can live on the AirPods themselves, or on your iPhone, and it can survive a simple forget-and-re-pair. A factory reset wipes the AirPods’ internal settings completely and starts fresh.
Fix:
- Place both AirPods Pro in the case and close the lid for about 30 seconds.
- Open the lid, then press and hold the button on the back of the case for about 15 seconds, until the status light flashes amber a few times, then flashes white.
- On your iPhone, forget the AirPods in Settings > Bluetooth if they’re still listed.
- Open the case near your iPhone to re-pair as if setting them up for the first time.
Verify: Run the Fit Test / Seal Test again, confirm Noise Cancellation mode, and test in a noisy environment. If ANC still isn’t working after a full reset and re-pair, this is very likely a hardware issue at this point.

Platform-Specific Fixes
On iOS
Most ANC troubleshooting happens here, since AirPods Pro settings, firmware delivery, and Control Center all live on iPhone and iPad.
Noise Control isn’t in Control Center
Don’t see the Noise Control panel when long-pressing the volume slider? Your AirPods probably aren’t actively connected. Reconnect via Settings > Bluetooth by tapping your AirPods Pro in the device list, then try Control Center again.
Firmware won’t update
Firmware updates go smoothest over Wi-Fi rather than cellular data, and Low Power Mode can interfere with the background install. Check Settings > Battery and turn off Low Power Mode while your AirPods charge nearby.
On macOS
Macs handle AirPods Pro connections and basic mode switching just fine, but the Ear Tip Fit Test / Acoustic Seal Test is iOS/iPadOS-only. Firmware updates, however, aren’t limited to iPhone or iPad: Apple’s documentation notes that AirPods firmware can update while your AirPods are near an updated iPhone, iPad, or Mac.
Switching noise control mode on Mac
Click the Sound icon in the menu bar (or go to System Settings > Bluetooth), select your AirPods Pro, and choose the noise control mode from the dropdown.
Firmware appears outdated on Mac but fine on iPhone
That’s usually just a timing difference rather than a platform limitation. Apple’s firmware update process can deliver updates while AirPods are near an updated iPhone, iPad, or Mac, so your Mac isn’t excluded, it may simply pick up the update at a different time. Keep your AirPods nearby with Wi-Fi on, and the firmware version should match across your devices once each one finishes checking in the background.
Settings to Check
These Settings paths come up over and over with AirPods Pro ANC issues:
- Noise Control mode: Settings > Bluetooth > ⓘ next to AirPods Pro; confirm Noise Cancellation, not Transparency, Off, or Adaptive Audio
- Ear Tip Fit Test / Acoustic Seal Test: Same AirPods settings page; run this any time seal or fit is in question
- Firmware version: Same page, under About; compare against Apple’s latest published version
- Software Update: Settings > General > Software Update; keep iOS current since it gates AirPods firmware delivery
- Low Power Mode: Settings > Battery; turn off before expecting a firmware update to install
When to Contact Apple Support
If nothing above fixed it, reach out to Apple when:
- ANC still doesn’t work after a full factory reset and re-pair
- Noise cancellation only fails in one AirPod, which suggests a specific microphone or driver fault
- You hear crackling, static, or distorted audio alongside weak ANC
- Your AirPods Pro are still within warranty or covered by AppleCare+
- The Ear Tip Fit Test consistently fails across all tip sizes in a properly cleaned ear
How to reach Apple Support:
- Apple Support website
- Apple Support app on iPhone or iPad
- Genius Bar appointment at your local Apple Store
Prevention Tips
To avoid running into this again:
- Clean regularly: Wipe down your AirPods Pro and ear tips weekly, especially the mic mesh, to keep earwax and debris from building up
- Recheck fit after tip swaps: Any time you change ear tip size, re-run the Fit Test / Seal Test to confirm the seal
- Keep firmware current: Let your AirPods charge near your iPhone with Wi-Fi on now and then, so updates install without you having to think about it
- Avoid unnecessary mode switching: If Adaptive Audio keeps confusing you, just leave Noise Cancellation selected as your default
- Store them properly: Keep AirPods in a case with a snug lid closure to protect the microphone mesh from pocket lint and moisture
Frequently Asked Questions
Why did my AirPods Pro noise cancellation suddenly stop working?
The most common causes, in order, are a loose ear tip seal, blocked microphones, an accidental switch to Transparency or Adaptive Audio, outdated firmware, or low battery. Work through those before assuming it’s hardware.
How do I check if my ear tips are the right size?
Run the Ear Tip Fit Test (AirPods Pro 1/2) or Acoustic Seal Test (AirPods Pro 3) from Settings > Bluetooth > ⓘ next to your AirPods Pro. Try all four tip sizes and re-test after each swap until you get a “Good Seal” result.
How do I know which noise control mode is currently active?
Open Control Center, long-press the volume slider, and look at the Noise Control panel; the active mode is highlighted. You can also check under Settings > Bluetooth > ⓘ next to AirPods Pro.
How do I update my AirPods firmware?
There’s no manual download for this. Place your AirPods in the case, connect it to power, and keep your Wi-Fi-connected iPhone, iPad, or Mac nearby for at least 30 minutes so the update installs on its own.
How do I reset AirPods Pro to factory settings?
With both AirPods in the case and the lid open, press and hold the button on the back of the case for about 15 seconds until the light flashes amber, then white. Then re-pair them as if new.
How can I tell if it’s a software problem or a hardware problem?
If ANC returns to normal after cleaning, checking modes, updating firmware, or resetting, it was software. If the problem sticks around after a full factory reset, especially in only one AirPod, it’s likely hardware, and you’ll need Apple Support.
When should I contact Apple Support or get my AirPods serviced?
Reach out if a factory reset doesn’t fix it, if you hear distortion or static, or if the issue is isolated to a single AirPod. That combination usually points to a microphone or ANC driver fault that needs repair or replacement.
Wrapping Up
Nine times out of ten, weak or missing ANC comes down to something small: a loose ear tip seal, a clogged mic, or the wrong mode selected. It’s rarely a broken product. Work through the fixes in order, starting with the Fit Test or Seal Test, and you’ll probably get full noise cancellation back long before you reach the factory reset step.

Setting up a new pair, or replacing a worn-out charging cable while you’re at it? Double-check you’re using a genuine Lightning or USB-C cable for the case. A flaky cable can mimic a lot of these battery-related symptoms, and it’s an easy thing to overlook.
