Do not support Apple's iOS
You've just removed your headphones from their packaging, opened the case, inserted them into your ears, and witnessed the noise cancellation technology in action. They're also less distracting than having a friend shout the answer at you when you're up at the chalkboard. This is a common issue for Android users, and it may be fixed by disabling the maximum volume in the developer menu or by making sure both sets of headphones are in sync. All of this is solvable, of course, but isn't that what you'd expect from headphones costing $21,000?
+ Furthermore, the options are limited to transparent mode and active noise reduction.
2. Sound
The sound is, to put it kindly, average, regardless of how highly they were rated.
Picture yourself in the midst of a large recording studio with the drummers at your back, the guitarist out to the side playing his part, and the singer right in front of you. To put it bluntly, this is the setting; the instruments are spread out rather than all clumped together, and each individual recording has sufficient volume.
And now we've forgotten all that, converted the room's ample space into a closet for the cleaning supplies, crammed everyone into here, and closed the door with our foot. The AirPods Pro have this kind of setting. Because all the noise is concentrated in one spot, it's difficult to tell how loud it actually is. It sounds like listening to the tunes on the second generation of AirPods, when the bass was deeper (who cares what anyone thinks, but in modern music the depth of the bass is vital and very even).
Glossy skin
It's absolutely gorgeous and futuristic-looking, and the materials are nice, but! In just six months, the surface will lose its shine due to wear and tear. It scratches by just being around other objects (yes, no one lied here; my headphones are less than a month old, and they already have scratches on the cover; no, I don't use them close to nails, keys, etc.
Fourth, noise cancellation still consumes audio and flattens it, albeit to be fair, it does this quite a little (in principle, noise cancellation consumes a small amount of audio everywhere).
