While the Bose 700 headphones don't beat the Sony WH-1000XM3 at active noise cancelling, they still do a great job. This is exactly the upgrade that Bose needed to make and I think doing so has made the Bose 700 headphones the most desirable pair of ANC cans on the market.
Great active noise ancelling; Sleek; new design; Gesture pad works perfectly; Better sounding than the QC35s
No folding hinges; Expensive; Microphone cuts off lower notes so people with deep voices won't come across as loud
