AirPod 4 has noise cancellation, but only in the more expensive model

Apple released two versions of AirPod 4 in September 2024. The standard model does not include active noise cancellation. The AirPod 4 with Active Noise Cancellation is a separate product that costs more — currently $129 compared to $99 for the standard version. If noise cancellation matters to you, you need to buy the specific model labeled as having it, not just any AirPod 4.

The difference is not just a software toggle you can turn on later. The two models have different internal hardware. The version with noise cancellation includes additional microphones and processing chips designed to detect and cancel ambient sound. You cannot add this feature to the standard AirPod 4 through an update.

Key Takeaways

  • AirPod 4 comes in two versions: one without noise cancellation at $99, and one with active noise cancellation at $129.
  • Active noise cancellation on AirPod 4 requires different internal hardware, so you cannot enable it on the standard model through a software update.
  • The noise-cancelling version also includes Adaptive Audio, which blends outside sound with your audio so you can hear announcements or conversations.
  • Both versions have Conversation Awareness, which automatically pauses audio when you speak so you do not have to remove the earbuds.

How active noise cancellation works on AirPod 4

Active noise cancellation on AirPod 4 uses outward-facing and inward-facing microphones to pick up ambient noise — traffic, background chatter, machinery — and then generates an inverse sound wave to cancel it out. This happens continuously while you are wearing the earbuds. The result is quieter surroundings, which makes music, podcasts, and calls clearer without turning up the volume.

The feature works best with consistent, low-frequency sounds like airplane engines, air conditioning hum, or highway traffic. It is less effective at blocking sudden or high-pitched noises like a car horn or a dog barking. If you are in a very quiet environment already, you may not notice much difference because there is less noise to cancel.

Adaptive Audio and Conversation Awareness on the noise-cancelling model

The AirPod 4 with Active Noise Cancellation also includes Adaptive Audio, a feature that blends outside sound into your audio stream. Instead of blocking all ambient noise, Adaptive Audio lets you hear announcements at an airport, a doorbell, or someone calling your name while you are still listening to music or a podcast. You control how much outside sound comes through using the volume slider in Control Center on your iPhone or iPad.

Both the standard and noise-cancelling versions of AirPod 4 have Conversation Awareness, which automatically pauses your audio when you start speaking. This means you can have a conversation without removing the earbuds or manually pausing playback. When you stop talking, audio resumes after a few seconds.

Battery life and transparency mode

The standard AirPod 4 offers up to 6 hours of listening time on a single charge, with the charging case providing up to 30 hours total. The noise-cancelling version has the same battery life — Apple did not reduce it to power the additional hardware. Both models support the same charging case, though you need the case designed for your specific model.

Transparency mode is available on both versions. This feature lets outside sound pass through to your ears so you can hear your surroundings without removing the earbuds. On the noise-cancelling model, you can switch between Active Noise Cancellation, Adaptive Audio, and Transparency mode using the stem on the earbud or through your device settings.

Comparing AirPod 4 to other Apple earbuds with noise cancellation

Apple makes two other earbud models with active noise cancellation: AirPod Pro (2nd generation) and AirPod Max (which are over-ear headphones, not earbuds). The AirPod Pro cost $249 and offer stronger noise cancellation than AirPod 4, along with additional features like adaptive transparency, personalized spatial audio, and conversation awareness that works in more situations. The AirPod Pro also have longer battery life — up to 6 hours per charge, same as AirPod 4, but they support lossless audio when connected to an Apple device via a wired connection.

If you want noise cancellation from Apple and want to spend less than AirPod Pro, the AirPod 4 with Active Noise Cancellation is the only option. If you do not need noise cancellation at all, the standard AirPod 4 at $99 is the least expensive Apple earbud currently sold.

What to check before buying

When shopping for AirPod 4, verify which model you are looking at. The product page or listing should clearly state "with Active Noise Cancellation" or "without Active Noise Cancellation." The price difference is $30, so it is worth confirming before checkout. Both models work with iPhone, iPad, Mac, Apple Watch, and Apple TV, and both support the same Bluetooth connection method.

If you are buying from Apple directly, the two models are listed separately on their website. If you are buying from a retailer like Best Buy or Amazon, read the product title and description carefully, because both versions are often sold side by side. The packaging also shows which features are included, so if you are buying in a store, you can check the box before purchasing.

Frequently Asked Questions

Can I turn off noise cancellation on AirPod 4 if I do not want it?

Yes. On the noise-cancelling model, you can switch to Transparency mode or turn off both features entirely through your device settings. You do not have to use active noise cancellation just because your earbuds support it. You can also use Adaptive Audio instead, which lets some outside sound through while still reducing loud background noise.

Will Apple add noise cancellation to the standard AirPod 4 in a future update?

No. Active noise cancellation requires specific microphones and processing hardware that the standard AirPod 4 does not have. Software updates cannot add hardware features. If you want noise cancellation, you would need to purchase the AirPod 4 with Active Noise Cancellation or a different model.

Is the noise cancellation on AirPod 4 as good as AirPod Pro?

The AirPod Pro have stronger noise cancellation because they use more advanced microphones and processing power. For most everyday situations — commuting, working in a noisy office, blocking background noise during calls — AirPod 4 noise cancellation is effective. If you need maximum noise isolation, AirPod Pro are the better choice, but they cost $120 more.

Do I need to pair the two AirPod 4 models differently?

No. Both versions pair with your Apple devices the same way. Open the charging case near your iPhone or iPad, and a setup screen appears. The pairing process is identical whether you have the standard or noise-cancelling model.
