OK, Just picked mine up at lunchtime (in Brisbane, AU) and I'm surprised at the amount of noise cancellation on a busy street, it's pretty scary!.
For reference, I've been using Gen 1 AirPods since release to cycle to work every day (never had an issue with them falling out or sweat related mishaps!) and Beats Studio 3 at work and flights.
I always found the Beats sound not quite as 'excited' as the AirPods which I really missed. However, bass at low volume and sound was great. Recently did a trip to the UK and wore them pretty much the entire trip. The bass on the AirPods Pro is slightly less at lower volume but really punches perfectly for me at louder volumes.
I work in an office and I can hear a lot less with these on compared to the Beats. The clicks on my keyboard as I am typing are more like little clip clip clip sounds.
I'm finding the new controls on the AirPods Pro a bit clunky, but I'm sure I'll get used them. I think the old 'whack the ear' when riding my bike will be probably easier than the squeeze, but then again, these now have the Hey Siri, so maybe I need to get onto that so that when winter comes again I won't be knocking them out my ears with gloves on!
Supposed 'audiophiles' will say what the want about them, but it's also personal - no two people have the same set of ears. Are they expensive? You bet. Are they comfortable, fit in with your phone super easy and keep a tiny form factor? Yup.
