Noise cancellation on AirPods Pro works through three different modes you switch between, not a straightforward on-off toggle

AirPods Pro have three listening modes: Active Noise Cancellation (ANC), Transparency, and Off. You switch between them by pressing and holding the stem — the small stick on the back of each earbud — for about three seconds. The earbud will chime and tell you which mode you've entered. Most people set their AirPods to cycle through all three modes each time they press, so you can reach any mode within two presses.

Active Noise Cancellation reduces background sound by playing an inverted sound wave that cancels it out. It works best on steady, low-frequency noise like airplane engines, traffic, or air conditioning. It does not eliminate sudden noises or voices as effectively. Transparency mode lets outside sound in so you can hear what's happening around you without removing the earbuds. Off mode uses no noise cancellation at all.

The mode you're in persists when you disconnect and reconnect your AirPods, so if you set them to ANC before you leave your desk, they'll be in ANC mode the next time you put them in your ears.

Key Takeaways

  • Press and hold the stem on the back of either earbud for three seconds to cycle through Active Noise Cancellation, Transparency, and Off modes.
  • Active Noise Cancellation works best on steady background noise like engines and fans, not on sudden sounds or speech.
  • You can customize which modes appear in the cycle and set a default mode in the Bluetooth settings on your iPhone, iPad, or Mac.
  • Noise cancellation drains the battery faster than normal listening, so expect about four to six hours of ANC use versus six hours without it.

How to switch modes using the stem

The stem is the narrow part on the back of each earbud that sticks out slightly. Press and hold it — either the left or right earbud works — until you hear a chime and a voice tells you the new mode. This usually takes about three seconds. Release as soon as you hear the chime; holding longer does nothing.

By default, each press cycles through all three modes in order: Active Noise Cancellation, then Transparency, then Off, then back to Active Noise Cancellation. If you want to skip a mode or change the order, you can customize this in your device's Bluetooth settings (see the section below).

If you're not hearing a chime or voice announcement, your AirPods may not be connected to your device, or the volume on your device may be muted. Check that Bluetooth is on and your AirPods appear in your device's Bluetooth menu.

Customizing which modes appear when you press the stem

You don't have to cycle through all three modes. On an iPhone or iPad, open Settings, tap Bluetooth, find your AirPods Pro in the list, tap the information icon (a small circle with an "i"), and scroll down to "Press and Hold AirPods." You'll see options for the left earbud and right earbud separately. Tap either one and choose which two modes you want to cycle between — for example, you could set the left earbud to toggle between ANC and Transparency, and the right to toggle between ANC and Off.

On a Mac, open System Settings, click Bluetooth in the sidebar, find your AirPods Pro, click the information icon next to them, and look for "Press and Hold AirPods." The same options appear. You can set different behaviors for each earbud on Mac as well.

If you only use one mode most of the time, setting both earbuds to toggle between that mode and one other means you'll reach your preferred mode with a single press instead of cycling through two you don't need.

Understanding battery drain with noise cancellation on

Active Noise Cancellation uses more power than regular listening because the earbuds are constantly generating sound to cancel background noise. With ANC on, you'll get about four to six hours of listening time per charge, depending on volume and how much background noise is present. With ANC off, you'll get closer to six hours.

Transparency mode uses slightly less power than ANC but more than Off mode. If you're running low on battery and need your AirPods to last longer, switching to Off mode will extend your listening time by 30 minutes to an hour.

The charging case holds multiple full charges. A single earbud takes about an hour to charge fully in the case, and the case itself takes about two hours to charge via the Lightning connector or MagSafe charging case (depending on which model you have).

When noise cancellation doesn't work as expected

Active Noise Cancellation requires a good seal between the earbud and your ear canal. If the fit is loose, ANC will be much less effective. AirPods Pro come with four sizes of silicone tips: extra small, small, medium, and large. Try the next size up or down — the medium size is the default, but your ears may need a different fit. You can test the fit in Settings on iPhone: go to Bluetooth, tap the information icon next to your AirPods Pro, and tap "Ear Tip Fit Test." The app will play a tone and tell you if the seal is good.

ANC also works better on some types of noise than others. It's very effective on airplane engines, traffic, and HVAC systems because these produce steady, low-frequency sound. It's less effective on sudden noises like a door slamming, a dog barking, or someone talking, because the earbud can't predict and cancel those sounds in advance.

If ANC suddenly stops working, try disconnecting and reconnecting your AirPods in Bluetooth settings. If that doesn't help, restart your device. Persistent problems may mean the earbuds need a firmware update, which happens automatically when they're in the case and near your iPhone or iPad.

Switching between modes for different situations

Most people use Active Noise Cancellation during commutes, flights, or when they need to focus in a noisy environment. Transparency mode is useful when you're walking outside, in a store, or anywhere you need to hear what's happening around you without removing the earbuds. Off mode uses the least battery and is fine for quiet environments like your home or office.

You can also set a default mode that your AirPods start in when you first put them on. In Bluetooth settings on your iPhone, tap the information icon next to your AirPods Pro and look for "Automatic Ear Detection." If this is on, your AirPods will remember which mode you were in when you took them out and return to that mode when you put them back in. If you turn it off, you can set a specific default mode in the same menu.

Frequently Asked Questions

Can I turn off noise cancellation completely?

Yes. Press and hold the stem until you cycle to Off mode. Your AirPods will still play audio, but no noise cancellation or transparency processing will happen. This mode uses the least battery and is useful in quiet environments where you don't need either feature.

Why does noise cancellation sound weird or make my ears feel full?

This is normal when you first use ANC — some people describe it as a slight pressure or a hollow feeling. It usually goes away after a few minutes as your brain adjusts. If it persists or bothers you, try Transparency mode instead, or check that your ear tips fit properly using the Ear Tip Fit Test in Bluetooth settings.

Does noise cancellation work if only one earbud is in?

Yes, but it's less effective. ANC works best with both earbuds in place because they work together to cancel sound. With only one earbud, you'll still get some noise reduction, but it won't be as strong.

What's the difference between Active Noise Cancellation and Transparency mode?

Active Noise Cancellation reduces background sound so you hear less of it. Transparency mode amplifies outside sound so you can hear your surroundings clearly without removing the earbuds. ANC is for blocking noise; Transparency is for staying aware of your environment.

Do I need to do anything special to keep noise cancellation working?

Keep the silicone ear tips clean and dry, and make sure they fit snugly in your ears. Check the Ear Tip Fit Test occasionally to confirm the seal is still good. Your AirPods will update their firmware automatically when they're in the case near your iPhone or iPad, so you don't need to do anything manually.
