Reviews of AirPods 4 Active Noise Cancellation | 2024

Wondering if AirPods 4's Active Noise Cancellation is a game-changer? Dive into detailed reviews and find out if it's the upgrade you've been waiting for.

On September 10, Apple held its fall Apple Event, and the AirPods, which took up the shortest percentage of time, became the new product discussed most after the conference, especially the AirPods 4 with ANC—Apple's first semi-in-ear active noise-canceling headphones. Today, we'll take an in-depth look at active noise cancellation and how well the AirPods 4 with ANC works.

What is Active Noise Cancellation

We can understand active noise cancellation through a simple comparison. Imagine you are in a grocery filled with people talking, children crying, and promotional announcements over loudspeakers. If you feel uncomfortable, the quickest way to reduce the noise is to cover your ears with your hands, creating a relatively closed-off space between the noise and your ears. By using sound-blocking materials (in this case, your hands) to block external noise, you achieve what is known as passive noise cancellation.

We all know that sound travels through the vibration of a medium, and when sound waves are out of phase with each other, they theoretically cancel each other out. Active noise cancellation is based on this principle, allowing two sound waves to cancel each other when they meet, thereby eliminating noise. This technology was first applied in commercial aviation headsets and gradually expanded to road vehicles, mobile phones, headphones, and earbuds.

How's AirPods 4's Active Noise Cancellation

In Active Noise Cancellation mode, outward-facing microphones detect external sounds, and Airpods 4 (ANC) counter with anti-noise, canceling the external sounds before you hear them. The image below shows the results of our active noise cancellation test.

Based on the test results, the noise cancellation performance of the AirPods 4 is quite impressive for a semi-in-ear earbud category. However, compared to in-ear earbuds, there is still a noticeable gap.

Officially, it has been stated that The active noise cancellation of AirPods Pro 2 has been improved by up to 2 times compared to the AirPods 4 (ANC). In practical use, we found that it excels at suppressing low-frequency noises, such as air conditioning sounds.

However, its performance is average regarding high-frequency transient sounds, like brake noises or mechanical keyboard clicks. Overall, the AirPods 4 (ANC) delivers commendable noise reduction performance for an open-back noise-canceling earbud.
