[T]here’s no question how AirPods Pro compare to regular AirPods. The difference is like night and day. Amtrak trains are pretty noisy — especially at what we in the U.S. so adorably consider “high speeds” — but with AirPods Pro the clackety-clack rumble was effectively blocked out.

My corner store has a noisy refrigeration unit. With AirPods Pro on — playing nothing — I couldn’t hear it at all. I couldn’t tell that my dishwasher was running even though I was sitting right across from it in my kitchen.
The AirPods Pro's noise cancellation seems to be better than expected. Even MKBHD thought so too. I'm pretty sure it's no better than those in Bose and Sony over-ear headphones. But I'm going on some long haul flights soon and they are perfect testing grounds for this. I'll report back in a couple of weeks.
Also, an interesting tidbit:
The force sensor — the flat section on the earbuds stem that faces forward when in your ear — is effectively a button. But it’s not a button. It doesn’t actually move, and it doesn’t provide haptic feedback. But it acts like a button and — most importantly — sounds like a button. When you press it, the AirPod Pro plays a click. I use the singular AirPod there because the click only plays in the bud whose force sensor you pressed. The effect is uncannily like clicking a real button. In a similar way to how force touch trackpads on modern MacBooks and Touch ID iPhone home buttons feel like they truly click, the AirPods Pro force sensors feel like actual clicking buttons. They actually have more of a premium clicky feel than the truly clicking buttons on Apple’s wired EarPods, even though they don’t actually click. It’s uncanny, and Apple at its best.
