Got a version of these last time they were offered. The ANC is useless in that I can’t tell a difference one way or the other. The be aware function is pretty good and neat if you’re in the city. The sound quality is pretty good to my average ears
They refunded one pair that did not work, (got 2 pairs one pair works just fine) first just the right one did not work then neither did. I tried buying another pair and they do not work either. I think maybe they were not properly Refurbished.
