I ordered my pair directly from B&O upon receiving mail on H9 launch last week.
The sound is very tight, lots of dynamics, extremely detailed, they grow on me.
Noise cancelling is... Well it's worse than H8, true - it's there but almost non-existing.
But don't get me wrong - you forget about the NC once you start the music.
I sold my QC35 because MDR-1000x have such a great NC - H9 is nowhere near that NC.
Sound quality wise though - H9 is as good as wireless can get at the moment.
Extremely good B&O quality - they do get a lot attention on street and in metro.
Interesting thing: they look exactly as H7 - apart from discrete external microphones.
I even managed to misplace my H7 for H9 on my way to work and take my H7 thinking they were H9.
Anyway, strongly recommend them if you have money to burn..
I'll be happy to reply if you have any questions on H9 - listening to them as I write.
Cheers!7
