Yes, AirPod Pros have noise cancelling built in

AirPod Pros come with active noise cancellation (ANC) as a standard feature. This means the earbuds use microphones to listen to the sound around you, then play back an opposite sound wave that cancels out that noise before it reaches your ear. It works best on steady, low-frequency sounds — airplane engines, car hum, air conditioning — and less well on sudden or high-pitched noises like someone talking or a car horn.

The noise cancellation is not always on. You control it through your iPhone, iPad, or Mac settings, or by pressing and holding the stem on the earbud itself. You can turn it fully on, switch to a mode called Transparency (which lets outside sound in), or turn it off completely.

Regular AirPods and AirPods Max also have noise cancellation. The second-generation AirPods Pro (released in 2022) added a feature called Adaptive Audio that automatically adjusts between noise cancellation and transparency based on your surroundings, though you can turn this off if you prefer manual control.

Key Takeaways

  • AirPod Pros use microphones to detect outside noise and play a cancelling sound wave, which works well for constant low sounds like engine noise but not for sudden or high-pitched sounds.
  • You control noise cancellation through your device settings or by pressing the earbud stem — it is not always on by default.
  • Transparency mode lets you hear the world around you while still wearing the earbuds, useful when you need to hear someone talking or traffic.
  • Newer AirPod Pro models (second generation and later) include Adaptive Audio, which switches between noise cancellation and transparency automatically based on what it detects.

How active noise cancellation actually works

Active noise cancellation works by fighting sound with sound. The AirPod Pros have two microphones on each earbud — one pointing outward to pick up external noise, one pointing inward toward your ear canal. The processor inside the earbud analyzes the incoming noise thousands of times per second and generates an inverted copy of that sound wave.

When the original noise and the inverted copy meet, they cancel each other out through a physics principle called destructive interference. The result is silence, or at least much quieter sound. This is why it works so well on airplane engines or highway driving — those sounds are consistent and predictable. A dog barking or someone shouting is harder to cancel because the sound changes too quickly for the processor to keep up.

The battery cost is real. Active noise cancellation uses more power than passive listening, which is why AirPod Pros last about six hours with ANC on, but up to nine hours with it off. The second-generation Pro model improved this slightly.

Transparency mode and when to use it

Transparency mode does the opposite of noise cancellation. Instead of blocking outside sound, it amplifies it and plays it through the earbuds so you hear the world around you while still wearing them. This is useful when you are walking in traffic, waiting for someone to call your name, or need to hear a conversation without taking the earbuds out.

You can switch to Transparency mode the same way you turn on noise cancellation — through settings or by pressing the earbud stem. Some people use Transparency when they are at home or in an office, and switch to full noise cancellation when they want to focus or block distractions. Others leave it on Adaptive Audio and let the earbuds decide based on what they detect.

What noise cancellation does and does not do

Noise cancellation is not the same as soundproofing. It reduces sound, sometimes dramatically, but does not eliminate it completely. A loud alarm will still be audible. Someone speaking directly to you will still be heard, though quieter. The effect is strongest when you are stationary — moving around or turning your head can reduce how well it works because the microphones pick up different sounds from different angles.

Noise cancellation also works better in some environments than others. It excels on airplanes, trains, and in cars because the noise is constant and low-frequency. It is less effective in an open office where people are talking, or outdoors where wind noise and traffic are unpredictable. In those situations, Transparency mode or straightforward listening to music or a podcast may be more practical.

Comparing AirPod Pro models

The original AirPod Pros (2019) and the second-generation AirPod Pros (2022) both have active noise cancellation, but the newer model improved the feature. The second generation has a more powerful processor that cancels more noise, especially in the mid-range frequencies where human voices sit. Battery life also improved slightly.

The second generation added Adaptive Audio, which automatically switches between noise cancellation and Transparency based on your movement and surroundings. If you are walking, it might turn on Transparency so you hear traffic. If you sit down, it might switch to noise cancellation. You can turn this feature off if you prefer to control the mode manually.

AirPods Max, the over-ear model released in 2023, also have active noise cancellation and use the same technology as the Pro earbuds, though the larger size allows for more sophisticated audio processing.

Turning noise cancellation on and off

To control noise cancellation on AirPod Pros, press and hold the stem (the flat part below the earbud) for about two seconds. Each press cycles through the three modes: Active Noise Cancellation, Transparency, and Off. You will hear a chime in your ear when you switch modes.

You can also control it through your iPhone or iPad. Go to Settings, then Bluetooth, then tap the information icon next to your AirPod Pros. Scroll down to find the Noise Control section and choose your preferred mode. On a Mac, the process is similar: System Settings, Bluetooth, then the information icon next to your AirPods.

If you use Adaptive Audio, the earbuds will switch modes automatically, but you can still override this by pressing the stem to lock in a specific mode. The setting will stay locked until you press again.

Battery life with noise cancellation on

Active noise cancellation drains the battery faster than passive listening. With ANC on, AirPod Pros last about six hours on a single charge. With it off, they last up to nine hours. The charging case extends total listening time to about 30 hours, but that is measured with ANC off.

The second-generation AirPod Pros improved this slightly — they last about six hours with ANC on and up to nine hours with it off, which is the same as the original, but the processor is more efficient so the battery degrades more slowly over time. If you are on a long flight or commute, turning off noise cancellation when you do not need it will extend how long you can use them before needing the case.

Frequently Asked Questions

Do I have to use noise cancellation?

No. You can turn it off completely by pressing and holding the earbud stem until you cycle to the Off mode. Many people use Transparency mode instead, which lets you hear the world around you. You control which mode you want every time you use the earbuds.

Will noise cancellation work if I am moving around?

It works, but less effectively than when you are sitting still. The microphones pick up different sounds as you move and turn your head, which makes it harder for the processor to predict and cancel the noise. It is still useful, just not as powerful as in a stationary position.

Can noise cancellation block someone talking to me?

It reduces voices but does not eliminate them. Someone speaking directly to you will still be audible, though quieter. If you want to hear someone clearly, switch to Transparency mode or take out one earbud.

What is the difference between noise cancellation and Transparency mode?

Noise cancellation blocks outside sound by playing an inverted sound wave. Transparency amplifies outside sound so you hear it clearly while wearing the earbuds. They are opposite functions — one isolates you, the other connects you to your surroundings.

Do older AirPods have noise cancellation?

Regular AirPods (the non-Pro model) do not have active noise cancellation. AirPods Pro and AirPods Max both have it. If you own older AirPods and want noise cancellation, you would need to switch to the Pro model.
