Before I watched this, I thought AirPods Pro were the new over-the-ear headphones. I guess because Pro sounds like the most expensive and is the most expensive in Apple's other product lines.
I did know the difference; I just forgot. But it doesn't speak to a great naming scheme. The AirPods and AirPods Pro look nearly identical (and apparently will look even more identical soon). And the ones I was thinking in my head were Pro I at first mistakenly thought, "Oh those must be the AirPods Max Pro" (again the cost and high quality etc)—but nope, just Max.
Again this is coming from someone who did know all of these. The names aren't semantic enough to be memorable.
