Because the 700s are normally costlier, at $379 compared to the $349 list price of the second-gen QC 35s, their higher $110 discount in both “Triple Black” and “Silver Luxe” flavors still makes them 14 bucks more expensive than their “cousins” (for Amazon Prime subscribers only).
The Bose Noise Cancelling 700 do hold an undeniable advantage over the QuietComfort 35 II in their intuitive touch controls, while the battery life is rated at a decent but not exactly outstanding 20 hours of uninterrupted listening time on both models.
The overall sound quality and call clarity should also be pretty similar, and of course, you’ll get easy access to the most popular voice assistants out there regardless of your choice, as well as basic IPX4 water resistance.
