How to enable noise cancelling on your AirPods 4

Noise cancelling on AirPods 4 turns on through the Control Center on your iPhone, iPad, or Mac. Swipe down from the top-right corner of your screen (iPhone 12 and newer) or swipe up from the bottom (iPhone 11 and older), find the audio card showing your AirPods, and tap the noise control icon — it looks like three concentric circles. You'll see three options: Active Noise Cancellation, Transparency mode, and Off. Select Active Noise Cancellation.

On an Apple Watch, swipe up from the bottom of the screen to open Control Center, tap the audio card, and select Active Noise Cancellation the same way. If you're using a Mac, click the volume icon in the menu bar, select your AirPods from the list, and choose Active Noise Cancellation from the noise control menu.

Once you turn on noise cancelling, it stays on until you manually switch to Transparency mode or turn it off. You don't have to repeat the steps every time you put your AirPods in — the mode you last used will be active the next time you wear them.

Key Takeaways

  • Noise cancelling activates through Control Center on your iPhone, iPad, Mac, or Apple Watch by selecting the audio card and choosing Active Noise Cancellation.
  • AirPods 4 remember which noise mode you used last, so you won't need to reset it each time you wear them.
  • You can switch between Active Noise Cancellation, Transparency mode, and Off without removing your AirPods.
  • If the noise control option doesn't appear in Control Center, make sure your AirPods are connected and your device is running the latest software.

What each noise mode does

Active Noise Cancellation uses outward-facing microphones to detect ambient sound and plays an inverse sound wave through your AirPods to cancel it out. This works best for steady, low-frequency noise like airplane engines, traffic, or air conditioning. It reduces but doesn't eliminate sudden or high-pitched sounds.

Transparency mode does the opposite — it amplifies outside sound so you can hear conversations, announcements, or traffic while your AirPods are in. The microphones pick up ambient noise and play it through your AirPods at a volume you control.

Off disables both features, so you hear only what's playing through your AirPods plus whatever sound leaks through the earpieces naturally. This uses less battery than Active Noise Cancellation.

Troubleshooting when noise cancelling won't turn on

If the noise control option doesn't appear in Control Center, first check that your AirPods 4 are actually connected. Open Settings on your iPhone, go to Bluetooth, and confirm your AirPods show as "Connected." If they're not paired, tap them in the list and wait for the connection to establish.

Next, verify your device is running the latest software. Noise cancelling requires iOS 18.1 or later on iPhone, iPadOS 18.1 or later on iPad, macOS 15.1 or later on Mac, and watchOS 11.1 or later on Apple Watch. Go to Settings > General > Software Update to check for updates.

If your AirPods are connected and your software is current but noise control still doesn't appear, try forgetting and re-pairing your AirPods. Go to Settings > Bluetooth, tap the info icon next to your AirPods, and select "Forget This Device." Then hold your AirPods case near your iPhone with the lid open until the pairing screen appears.

Battery drain and noise cancelling

Active Noise Cancellation uses more battery than Transparency mode or Off because the microphones and processing run continuously. On a full charge, AirPods 4 last about 4 hours with noise cancelling on, compared to roughly 6 hours with it off. The charging case extends total listening time to around 20 hours with noise cancelling or 30 hours without.

If you're in a quiet environment or don't need noise cancelling, switching to Off or Transparency mode will extend your battery life between charges. You can also check your AirPods battery level in Control Center — if it's low, turn off noise cancelling to make them last longer until you can charge them.

Using noise cancelling with Siri

You can switch noise modes hands-free by saying "Hey Siri" followed by a command like "Turn on noise cancellation" or "Switch to Transparency mode." Siri will confirm the change and switch immediately. This works on any device where Siri is enabled and your AirPods are connected.

If Siri doesn't respond to your command, make sure Siri is turned on in Settings > Siri & Search on your iPhone or iPad. You also need to be within Bluetooth range of your device — typically 30 to 40 feet indoors.

Customizing noise control in Settings

You can set which noise mode appears first when you tap the audio card in Control Center. Open Settings on your iPhone, go to Bluetooth, tap the info icon next to your AirPods 4, and scroll to "Noise Control." You'll see options to choose which mode is your default and which modes appear in Control Center. Some users prefer to hide one mode entirely so they only cycle between two.

This customization syncs across all your Apple devices, so if you set a default on your iPhone, it applies to your iPad and Mac as well. You can change it anytime by returning to the same settings menu.

Frequently Asked Questions

Do I need to turn on noise cancelling every time I put my AirPods in?

No. AirPods 4 remember which noise mode you used last. When you put them in again, they automatically activate that same mode. You only need to manually switch if you want a different mode than the one you used previously.

Can I use noise cancelling while on a phone call?

Yes. Active Noise Cancellation works during calls and helps reduce background noise so the person on the other end hears you more clearly. You can also switch to Transparency mode during a call if you need to hear your surroundings.

Why does noise cancelling drain my battery faster?

Active Noise Cancellation requires the microphones and audio processing to run continuously, which uses more power than simply playing audio. Turning it off when you don't need it — like in quiet environments — will extend your battery life between charges.

What if noise cancelling makes my ears feel uncomfortable?

Some people experience ear pressure or discomfort with Active Noise Cancellation. Try switching to Transparency mode or Off to see if the feeling goes away. If it persists, take a break from wearing your AirPods for a while. The sensation usually fades as you get used to the feature.

Can I turn on noise cancelling without opening Control Center?

Yes, through Siri. Say "Hey Siri, turn on noise cancellation" and Siri will switch the mode immediately. You can also customize your AirPods settings to assign a specific noise mode to a double-tap gesture, though this requires using a third-party app since Apple doesn't offer this customization natively.
