Very easy and convenient! Surely will recommend friends and family to buy from here
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.
