I got these as a birthday gift from my girlfriend. The noise cancelling effect is pretty good, reduces outside noise by about 85% or so. With music on and playing, outside noise is pretty much gone. The "pressure" I feel from other noise cancelling headsets is greatly reduced, so that's great for me. The transparency option is great if you're listening to these at work or somewhere where you'll need to be aware of your surroundings.
My biggest concern was the fit of the AirPods Pro, because my OG airpods always felt like they would fall out, and would occasionally fall out during a run or workout. Thankfully, these come with small, medium and large silicon tips. The "ear fit test" said that the medium were a good fit for me, but I thought it could fit better and a better seal. I popped off the mediums(beware, the tips are very hard to pop off and you need to use more force than I'm comfortable with for small delicate electronics) and swapped them out for the large tips. They fit very snug in my ears, and don't budge with running or working out or just being active in general.
My only real complaints with them so far are the new "button" on them to pause, rewind, fast-forward, etc is a little weird and unnatural to use, but I suppose it's more reliable than the tapping the entire AirPod in older models. Also, the sound quality is decent bump from the original models, but nothing mind blowing.
