I am so angry right now. After spending months waiting for a deal on these i gave up and bought the Sony WH-1000XM2s for the same money.
These headphones get similar NC performance but their sound and build quality is next level. In addition this has USB C CHARGING! so you don't have to carry an additional cable around just to charge your headphones.
The only criticism in all the reviews is the $549 price in comparison to the Sonys or the Bose which can be had much cheaper. So this deal sorts that out.
I now live overseas now so can't even sell my Sonys and buy these :(
EDIT
These are also comparable to the Bose QC 35 in terms of performance but reviews say the noise quality and particularly the sound stage in these is class leading whilst the build and design is just gorgeous with the B&W set.
which one is better between this and sennheiser pxc 550? anyone tried both can share their experience?
