Usually I wouldn't bother writing about such a thing as an AirPod revision, but this one caught me off guard. It's basically a complete redesign internally and I think it paid off. If you haven't noticed I'm excited about the new AirPods Pro and I will most likely grab a pair for myself at some point. NOISE CANCELLING: In a quick test there was always some bass leakage with the old AirPods Pro with stock tips. I'm using stock tips here to make comparing easy (I don't have two pairs of the same aftermarket tips). This is despite a proper seal with good bass extension during listening. The AirPods Pro 2 fixes the bass leakage and even adds some better midrange isolation. I think it's not quite up to AirPods Max levels of isolation, but it beats out custom IEMs for me now. AirPods Pro 1 < CIEMs < AirPods Pro 2 < AirPods Max SOUND: In a word: smoother. The new AirPods Pro sort of fix the faults in the tonality of the original AirPods Pro. The bass has better integration with less of a hole in the lower midrange, the upper midrange is less harsh, the treble is smoother. As a result it can sound warm, but so far I like the new tonality. It pulls it off while also increasing the stage size aswell as microdynamics and resolution. It sounds clearer instead of sounding veiled. Very nice. I can't compare it against the other newer IEMs in the same price range and I bet those are better with a proper source, but obviously these serve a different purpose. And I will say that I use even my AirPods Pro 1 a lot more often than my UERM. They're perfect for a quick walk, etc. MISC: The rest is of course pretty similar. The case is much better with a built in speaker for cute pairing sounds and it even has a hole for a lanyard! That alone makes it a substantial upgrade in my opinion. And being able to find the case with a sound playing is super useful in theory, but I couldn't get it to work. The gestures all seem to work on Android. Volume, Play/Pause, NC/Transparency, Skip/Back, etc. Overall I think it's a worthy successor for sure.
