I have both. Over the ear is better but the earbuds that are 10+ years old are also better than recent APP2. I’ve not tried 3 and probably won’t.

The form factor is ridiculous by APP2 standards. There’s a corded stick that I assume has all the components in it as back then they wouldn’t fit in earbuds themselves. That’s apples main innovation. But, honestly, when I’m on a flight I will take a 10% performance boost over a slicker design or smaller form factor. My guess is they’re at least 50% better and only slightly inferior to over the ear ones.

All said, I usually just take my over the ear bose on a flight. I got the APP2 specifically for that purpose but they are awful in my opinion. About once a year I make the mistake of trying them out again and immediately regret it before the plane even starts taxiing.
