I had a pair of Bose QC35's and I loved them. Super comfortable, good noise cancellation and pretty good sound. I read that these Sony's are better in every way. A tall order ... that the Sony's more than live up to.
The noise cancelling is amazing. Sound quality blows the Bose out of the water. Nice and comfy too, and better battery life. Very, very happy.
About the only negative is they don't do multi device pairing like the Bose does; you can only be connected to one music source at a time.
