The distinguishing attribute of the Bose 700 is the crystal clear call quality, not only for you, but also for the person on the other side of the call. I have tried other noise-cancelling headphones, but the one thing those were not good at was call quality - noise from traffic, crowds, and the blowing wind (the worst offender) interfered and made using those headphones for calls unbearable. with Bose 700, I have made calls from crowded Times Square, windy Central Park, and noisy Sixth Avenue - the people on the other side did not have any problems hearing me, and I felt like I was in an shut-door office.The other excellent feature is the notifications (I use Google Assistant) that allows one, at a click of the button, to listen to notifications, texts, messages, and email headers. One can also use the assistant to reply to messages and texts.Cons: Price; wish it were similarly priced to the QC 35IIs or the Sony 1000s. But I do not regret spending the $400!
