My wife's headphones broke so she took my PXC 550 (first gen), so I upgraded to 550 ii. Great headphones. Noise cancelling works well. Easy setup with iPhone XR, and also works with Lenovo X1 (Debian 10).
With the active noise cancelling, I can work in peace, have clarity during meetings, and even game with no disturbances.
I love the product! But right side of the head band extension alittle loose as compared to the left. Not too big of a bother, and i dont think i can get an exchange over this small flaw. But anyway, still a good product.
