AirPods 4 include active noise cancellation, but it works differently than AirPods Pro
Yes, AirPods 4 have active noise cancellation (ANC). Apple added this feature to the standard AirPods line for the first time in 2024. However, the noise cancellation on AirPods 4 is less powerful than what you get with AirPods Pro or AirPods Max. The AirPods 4 version reduces background noise noticeably — traffic, airplane engines, office chatter — but does not eliminate it the way the Pro models do.
The difference comes down to hardware. AirPods Pro have two microphones per earbud and a custom chip designed specifically for noise cancellation. AirPods 4 have one microphone per earbud and use the standard H4 chip that also handles other functions. This means AirPods 4 can cancel lower frequencies (like engine rumble) reasonably well, but struggle more with higher frequencies (like voices or keyboard typing).
Key Takeaways
- AirPods 4 have active noise cancellation that reduces background noise but does not eliminate it completely.
- The noise cancellation on AirPods 4 is noticeably weaker than AirPods Pro because they use different microphone and chip hardware.
- AirPods 4 also include Adaptive Audio mode, which blends noise cancellation with transparency so you hear some outside sound while still reducing noise.
- If you spend most of your time in quiet environments, AirPods 4 noise cancellation may be sufficient; if you travel frequently or work in loud offices, AirPods Pro will perform better.
How AirPods 4 noise cancellation performs in real situations
In a quiet room, you will barely notice the noise cancellation because there is little to cancel. The real test is environments where you actually need it. On a commercial flight, AirPods 4 will reduce the engine noise enough that you can hear music or a podcast without turning the volume up dangerously high, but you will still be aware of the rumble underneath. In a busy coffee shop, they will soften the ambient chatter and espresso machine noise, but someone speaking directly to you will still come through clearly.
The weakness shows up most in open offices and video calls. If you are trying to focus on work while coworkers talk around you, AirPods 4 will help but will not create the quiet bubble that AirPods Pro provide. During video calls, the single microphone per earbud means the noise cancellation on the other person's end (if they are using AirPods 4) will not filter out your background as effectively as it would with Pro models.
Adaptive Audio mode gives you a middle ground
AirPods 4 include a feature called Adaptive Audio that AirPods Pro also have. This mode blends active noise cancellation with transparency mode — you hear your music or call, but also some of the world around you. You can adjust the slider to let in more or less outside sound depending on what you are doing. This is useful if you want to focus on audio but still hear a doorbell, a child calling, or traffic when you are walking.
Adaptive Audio works better on AirPods 4 than straight noise cancellation does, because it is not trying to do the impossible job of blocking everything out. Instead, it is just reducing volume while letting real-world sound through. Many people find this mode more practical for everyday use than either full noise cancellation or full transparency.
Transparency mode lets you hear everything without removing the earbuds
Both AirPods 4 and AirPods Pro include transparency mode, which uses the microphones to pick up outside sound and play it through the earbuds. This means you can hear someone talking to you, a car horn, or an announcement without taking the earbuds out. On AirPods 4, transparency mode works well — the audio is clear and responsive.
The difference between transparency on AirPods 4 and AirPods Pro is subtle. AirPods Pro transparency sounds slightly more natural because of the extra microphone, but both versions let you hear what is happening around you. If transparency mode is your main use case, AirPods 4 will do the job.
When AirPods 4 noise cancellation is enough
AirPods 4 are a reasonable choice if you work in a quiet or semi-quiet environment, use them mainly for calls and podcasts rather than music, or do not travel frequently. They will reduce distracting background noise without the cost of Pro models. If you spend most of your time in your home, a library, or a quiet office, the difference between AirPods 4 and AirPods Pro noise cancellation will not matter much in practice.
They are also a good fit if you want noise cancellation but find AirPods Pro uncomfortable or too expensive. AirPods 4 are smaller and lighter, and many people find them easier to wear for long periods. The noise cancellation, while not as strong, is still a meaningful improvement over no noise cancellation at all.
When you should consider AirPods Pro instead
If you travel by plane or train regularly, work in a loud open office, or spend significant time in noisy environments, AirPods Pro will give you noticeably better noise cancellation. The difference is not subtle — AirPods Pro can reduce airplane cabin noise by roughly 30 decibels, while AirPods 4 manage around 20 decibels. That gap matters when you are trying to sleep on a flight or focus during an eight-hour workday.
AirPods Pro are also the better choice if you use your earbuds for music listening and want the best possible sound isolation. The stronger noise cancellation means you can listen at lower volumes, which is better for your hearing over time. If budget is not a constraint, AirPods Pro are the safer choice for anyone who spends time in genuinely loud environments.
Other audio features that come with AirPods 4
AirPods 4 include features beyond noise cancellation that may matter to you. They have conversation awareness, which automatically lowers your audio and turns on transparency when it detects someone speaking to you. They support spatial audio with dynamic head tracking, which creates a surround-sound effect when you are watching video. They also work with Find My, so you can locate them if you lose one.
Battery life is eight hours of listening time per charge, or six hours if you use noise cancellation continuously. The charging case holds multiple charges. These specs are the same as earlier AirPods models, so noise cancellation does not drain the battery faster than you would expect from standard AirPods.
Frequently Asked Questions
Do AirPods 4 noise cancellation work on phone calls?
Yes. When you are on a call, AirPods 4 use noise cancellation to filter out background noise on your end so the other person hears you more clearly. However, the single microphone per earbud means the filtering is not as aggressive as it is on AirPods Pro. In very loud environments, the other person may still hear some background noise.
Can you turn off noise cancellation on AirPods 4?
Yes. You can switch between noise cancellation, transparency mode, and off (no active processing) by pressing and holding the stem on either earbud, or by using the Control Center on your iPhone or iPad. You can also customize which mode each press activates.
Do AirPods 4 noise cancellation work with Android phones?
AirPods 4 will connect to Android phones and tablets, and noise cancellation will function. However, some features like Adaptive Audio and conversation awareness may not work as smoothly on Android as they do on Apple devices. The core noise cancellation feature itself works fine.
How long does it take to notice a difference with noise cancellation on?
You should notice the effect immediately when you turn on noise cancellation — background noise will drop noticeably within a second or two. The effect is most obvious in steady, low-frequency noise like airplane engines or traffic. Higher-frequency sounds like voices take longer to filter and may not be reduced as much.
Will AirPods 4 noise cancellation help if I have tinnitus?
Noise cancellation may help mask tinnitus in loud environments by reducing the contrast between background noise and the ringing sound you hear. However, in quiet environments, noise cancellation might make tinnitus more noticeable because there is less external sound to mask it. Results vary by person — you would need to test them yourself.
