That is pretty good offer, those are bit better than mine. I am using cheaper Sennheiser model with noise cancelling,
Sennhesier HD 4.50 and i am pretty satisfied with sound quality and noise cancelling.
If money is not an issue or you don't mind giving a bit extra, i would suggest that you go for
Sony WH-1000 X M3, or if there is a good offer for older version, Sony WH-1000 X M2, very comfortable and best ANC(active noise cancelling ) on the market. Bose QuietComfort 35 is also close to those, especially if you can find good offer.
