> Built-in heart rate monitor is intended for use during workouts with the Fitness app and compatible third-party apps on iPhone running iOS 26 and later.
Why is it Fitness app only? Odd restriction.
Also explicit confirmation of foam-assisted tips:
> And five all-new ear tips — including an XXS option — fuse a thin layer of soft foam to the silicone shell to give you even better acoustic performance.
It's not... The compatible third-party apps part means basically any app integrating with the API, presumably.

I had a set of foam-integrated silicone tips on my Airpods Pro 2 and I LOVED them. All the fit benefits of foam with the easy cleaning of silicone! Wish they'd release first-party versions for the Airpods Pro 2, cause that's the only change I'd really like. Single charge battery usage and ANC are great, but I get by just fine with the AP2 (ANC is already excellent, so I'm really curious what the AP3s sound like in comparison).
