AirPods are certainly super popular, but I can't think of many places that are extreme outliers in almost every category like the Bay Area. A lot of startups have failed assuming their business that worked for Bay Area customers would work elsewhere.
This is true but airpods is a bad example. They are a runaway success. Estimates are they did around $25bn of revenue in the last year. For context the highest annual revenue Bose ever did was $4bn (since declined). Sonos does something like $1.5bn. If Airpods was a standalone company it would be one of the biggest consumer hardware companies in the world.
