From Daring Fireball:

I’m genuinely curious why Apple doesn’t offer AirPods in more colors. Seems like something people would enjoy, especially black. My best guess is that Apple considers white earbuds to be iconic and part of the Apple brand.

That sounds right to me, and it’s one of those unfortunate cases where what’s best for Apple comes before what’s best for its customers. I’ll grant you it offers an opportunity for third-party companies to colour your AirPods, but the AirPods Pro are already CAD$329—I don’t think I’ll be in the after-market. 😂
