I rarely see any earbuds except AirPods in the US, they are the overwhelming majority. Several other countries I’ve worked in also have pretty ubiquitous AirPods penetration, though not quite at the level of the US.

I have a few friends that bought every inexpensive alternative to AirPods, had a poor experience with all of them, finally relented and bought AirPods. Now they won’t use anything else. They spent more money avoiding AirPods than buying them.

Apple did a really good job with the AirPods.
