Just got mine today here in Melbourne, Aus.
...I played my first song. I started without noise cancelling to try it out.
Hmm. Something must be wrong there's absolutely no depth to the sound.
Okay let's try a different song. Nope, same thing.
Maybe noise cancelling on will make a difference? Nope.
Then I compared them back to back with the OG AirPods. Wowee!! I just burst out laughing. THERE's my audio!
The sound quality difference is insane. Very, very disappointed in these for a $400 product.
It's a shame because, throughout my other testing I was thoroughly impressed.
The noise cancelling is incredible. Like, really really good. They fit better in my ears, are much more comfortable, much more discreet looking, less awkward, finally has a better control scheme, integrates better etc.
But in cramming all those awesome developments it seems Apple forgot about the whole point of headphones. The audio.
Real shame.
