The comfort is good, the battery life is excellent, and the materials appear to be of high quality.

Battery life isn't very good with ANC

The sound and ANC is unrivaled and the battery life is fantastic

I tired these, as well as, the Bose QuietComfort 35 II's, and I must say that these are superior

I have rated them four stars so far as I very nervous that these will break as many other people have posted in other reviews.
