How to Enable and Use Noise Cancellation on AirPods

Apple's AirPods have become one of the most recognizable pairs of earbuds on the market, and a big reason for that is Active Noise Cancellation (ANC) — a feature that uses microphones and signal processing to actively reduce the ambient sounds around you. But not every AirPod model includes it, and the way you enable and control it varies depending on your device, iOS version, and how your AirPods are set up.

Here's a clear breakdown of how noise cancellation works on AirPods, how to turn it on, and what shapes the experience.

Which AirPods Models Support Noise Cancellation?

Before diving into settings, it's worth knowing that ANC is not available on every AirPod model. This is the first variable that determines everything else.

If you have standard AirPods (non-Pro), noise cancellation simply isn't part of the hardware. The 3rd-gen AirPods do include Adaptive EQ and Transparency Mode, but those are different from true ANC.

How Active Noise Cancellation Actually Works

ANC on AirPods uses outward-facing and inward-facing microphones to detect external sound. The chip inside the earbuds (the H1 or H2 chip, depending on model) processes that audio and generates an anti-noise signal — essentially the inverse waveform — that cancels out ambient sound before it reaches your ears.

This happens continuously, thousands of times per second. The result is a noticeable reduction in low-frequency sounds like airplane cabin noise, HVAC systems, and traffic hum. Higher-frequency, sharper sounds (like voices or sudden noises) are harder to cancel entirely, which is why ANC works better in some environments than others.

The AirPods Pro 2nd gen introduced an upgraded H2 chip with improved noise cancellation performance compared to the original Pro model — a meaningful generational step in processing capability.

How to Turn On Noise Cancellation on AirPods 🎧

There are several ways to activate ANC, and which method works for you depends on your device and preferences.

Method 1: Press the Force Sensor (AirPods Pro)

On AirPods Pro, press and hold the force sensor on the stem of either earbud. This cycles through your available listening modes: Noise Cancellation → Transparency → Off (or a custom configuration you've set).

Method 2: Control Center on iPhone or iPad

1. Open Control Center (swipe down from the top-right on Face ID devices, or swipe up on older models)
2. Long-press the volume slider
3. A panel appears showing your AirPods and the current listening mode
4. Tap the Noise Cancellation icon (the ear with lines)

This is one of the quickest access points when your AirPods are already connected.

Method 3: Settings App

1. Go to Settings → Bluetooth
2. Tap the "i" icon next to your AirPods
3. Under Noise Control, select Noise Cancellation

This menu also lets you customize what the force sensor press cycles through — useful if you want to skip Transparency Mode and toggle only between ANC and Off.

Method 4: Siri

Say "Hey Siri, turn on noise cancellation" — Siri can switch listening modes hands-free, which is especially handy when your hands are occupied.

On Mac

Click the Control Center icon in the menu bar → Click your AirPods → Select the noise control mode from the dropdown.

What Affects How Well Noise Cancellation Performs

Even with ANC enabled, the actual experience varies considerably. Several factors play into this:

Ear tip fit is arguably the most important variable on AirPods Pro. A poor seal between the silicone tip and your ear canal dramatically reduces ANC effectiveness — passive isolation and active cancellation work together. AirPods Pro include an Ear Tip Fit Test (under Settings → Bluetooth → your AirPods) that uses microphones to evaluate your seal and recommends a different tip size if needed.

Environment type matters because ANC handles steady-state, low-frequency noise (engines, fans, AC units) far better than it handles unpredictable high-frequency sounds. Expecting it to silence a loud conversation completely will lead to disappointment; expecting it to significantly reduce cabin roar on a plane is reasonable.

iOS version can affect available features. Apple has added and refined ANC-related options — including Adaptive Transparency and Conversation Awareness on AirPods Pro 2 — through software updates. Keeping your iPhone updated ensures you have access to the full feature set your hardware supports.

Battery level can influence ANC performance, as the feature requires active processing power. Most users won't notice this in normal use, but it's a known variable at very low charge levels.

Transparency Mode: The Other Side of the Coin

It's worth understanding that Transparency Mode is the intentional opposite of ANC. It uses the same microphone system to let outside sound in, blending ambient audio with your music so you can hear your surroundings — useful for crossing streets, conversations, or public announcements.

AirPods Pro 2 introduced Adaptive Transparency, which automatically reduces sudden loud sounds (like construction or a siren) while still letting in ambient audio. This is a different behavior from the static Transparency Mode on earlier models.

The Setup Matters More Than the Feature

Noise cancellation on AirPods is genuinely capable hardware — but whether it solves the problem you're trying to solve depends on your specific model, how well the ear tips fit your ears, the acoustic environment you're in, and which iOS features your device supports. Two people using AirPods Pro in different conditions can have meaningfully different experiences with the same settings turned on. Your own setup — the model you own, the fit you're getting, and the environments you're in most — is the piece that determines how much of that capability actually reaches you.
