Apple AirPods 4 hands-on: Seriously impressive ANC performance

Two models of AirPods were largely expected at today's iPhone 16 event, one of which would add active noise cancellation (ANC) to the "regular" AirPods for the first time. There are other upgrades for the $179 version, but after a brief demo of the ANC setup on the AirPods 4, I wager the noise-blocking tools will be the key selling point for most people.

Apple is using this version of the AirPods 4 to bridge the gap between the AirPods and the AirPods Pro. As such, this model has some features that were previously exclusive to the company's priciest buds. Those include Siri interactions that allow you to accept or reject calls with a head nod, Adaptive Audio, Voice Isolation and more — all thanks to the H2 chip that powers the Pro model. All of these will be welcome improvements for people who prefer the open fit of the AirPods 4, but the ANC is the most impressive addition in my book.

I got a brief demo of the AirPods 4 with active noise cancellation in the chaotic hands-on area at Apple Park. Honestly, it's a perfect place to test ANC. Once I had the AirPods 4 in my ears and I got some music going, I activated noise cancelling to silence the room. And it nearly did. I was blown away by how effective the ANC is on these earbuds that don't completely seal off your ears. Most open-type designs with ANC barely put a dent in ambient distractions, but do affect battery life. Here, I might as well have been in a room on my own, and I was only aware of the environmental noise when transparency mode jolted me back to reality.

Apple updated the design for the AirPods 4, calling them "the best-fitting AirPods ever." This refined shape, in addition to some software tricks and acoustic performance, helps boost passive noise isolation while keeping your ears open for that default audio mode. ANC is yet another place Apple is able to flex the muscle of the H2 chip, and the AirPods 4 performance in that regard is a testament to the component's abilities.

I will note that transparency mode on the AirPods 4 didn't sound as natural as it does on the AirPods Pro. That's mostly due to the fact that I didn't feel like the earbuds were piping in as much of my own voice as that pricier model. In fact, I felt like it hardly did so at all. An Apple rep explained that the difference could be attributed to a number of factors, including the fact that my ears weren't completely closed off.
