If you’re experiencing crackling or static sounds in your AirPods Pro, or if Active Noise Cancellation isn’t working correctly, Apple will replace the affected earbuds for free.

Through a series of circumstances, Adam Engst ended up with both a pair of AirPods and a pair of AirPods Pro. When free to choose one or the other at any time, which did he pick? The answer—and what he recommends—might surprise you.

Many early adopters of the AirPods Pro say that Apple has released firmware updates that have reduced the efficacy of the noise-cancellation algorithm. Users are allowed no control over what firmware revisions their AirPods Pro get, and Apple has yet to comment on the situation.

Apple has expanded upon its hit AirPods with new AirPods Pro models. They fit and sound better, courtesy of silicone ear tips, and add audio features like noise cancellation and a “transparency mode." The previous generation AirPods aren’t going anywhere, though.
