Apple AirPods 4 review: I flew 3,319 miles on a plane with active noise cancellation, but was it good?

"When will Apple tackle smell cancellation?" was all I could think of while testing the AirPods 4 on a flight from San Jose, Calif. to Atlanta. Unfortunately, I dealt with a flatulent neighbor who kept letting one rip.

Phew!

But while my nostrils were fighting for their life on a Boeing 737, my ears had a different experience: a blissful, quiet ride during an eight-hour trip from California to New York (with a malodorous connecting flight to Atlanta between the journey).
