I've had a few hours to try them out and here are some initial observations.
Before I start FindMy still doesn't work for me despite unpairing and resetting them, so I can't comment on that functionality.
I never had the 1st Gen AirPods Pro so I can't really compare to them. However, I have AirPods Max and have owned 2nd and 3rd Gen AirPods.
- I still can't get used to Dolby Atmos, and think it sounds muddy in comparison to regular stereo. Depends on the song of course, but I rarely find a song where I'd rather listen to the DolbyAtmos version vs. stereo. AirPods Max didn't convince me of DolbyAtmos, so it was only natural the Pros wouldn't either. As per the AirPods Max and 3rd Gen AirPods, Head Tracking is a bit gimmicky - when listening to music at least.
- Bass is impressive and full given the size. Of course, it's not as deep and as rich as the AirPods Max but like someone said earlier, it's like comparing a truck to a MINI Cooper. For the size the bass is very impressive.
- Noise cancellation is great for me. According to the ear fit test the mediums provide the best seal for me. Granted, it does let more noise in than the AirPods Max, but it's still quite hard for me to get my head around how these small buds can cancel out as much noise as they do.
- Transparency mode is a highlight for me. Also being able to access quality of life changes like adaptive transparency is great. I have mild autism so loud noises can really grate on me and these have a nice way of dulling that noise, but without having to block everything out.
- The noises on the charging case are nice to have. Not essential of course (except for with FindMy, when it works for me that is) but a definite nice to have. It makes the Apple Watch charge noise when you put it on an apple watch charger! (Haven't tried it on other wireless chargers yet so it probably makes the same sound there aswell).
- The sound is improved on iOS when choosing different modes in the Headphone Accommodations section. I tend to like the 'Brightness' setting which is what I have it on. Try it out if you haven't already! Unfortunately macOS doesn't have these settings.
