AirPods 4 active noise cancellation
As mentioned at the outset, with the ANC-enabled AirPods 4, I flew from San Jose, Calif. to Atlanta before hopping on another NYC-bound flight.
I spent nearly eight hours with the AirPods 4 in my ears. As I hinted in my
hands-on review, the AirPods 4 sounded like honey to my ears
— and even more so when ANC was on. While I was at the airport, sounds of coo-ing babies, loud conversations, and rolling luggage were significantly reduced, allowing me to sink deeper into some of my favorite Apple Music playlists.
It was as if the AirPods 4 erased the cacophonous world around me, allowing me to sit in a quiet, empty void, with nothing but myself, my earbuds, and Sabrina Carpenter. "Me Espresso" already sounds darn good, but on the AirPods 4, it sounds immaculate.
Did I hear the airplane engine?
No headphones are going to
completely get rid of engine noise. For example, when I compared the
AirPods Max and Sony XM5s, two high-priced over-ear headphones, even
they had some external noise leak through the devices. (But the AirPods Max did a better job at handling ANC.)
However, the AirPods 4 did, in fact, significantly reduce the drone of the airplane engine. I noticed the ANC eliminated the high-pitched whine of the plane, creating a much more pleasant listening experience. However, it didn't completely get rid of the lower, rumbling sounds of the engine
— it was still faintly noticeable.
It reduced it, yes, but it didn't eliminate it completely, which is, again, par for the course for ANC. Overall, the AirPods 4 did a great job at dampening the sound of the plane as it ripped through the air at more than 500 miles per hour.
ANC is a rarity in open-ear designs
People may underestimate how unusual it is to get ANC support in an open-ear design like the AirPods 4. As I mentioned in my hands-on, unlike the AirPods Pro 2, the AirPods 4 do not feature silicon tips. As such, it doesn't have a tight seal stuffed in your ears to support ANC technology in blocking external sounds.
However, Apple boasted that it was able to accomplish this engineering challenge by using upgraded microphones (the same ones found on the AirPods Pro 2), the H2 processor, and cutting-edge computational audio.
