A:Answer I have both. For noise cancelling, I would say these are better than QC35s. These come with touch sensitive features on the right ear cup. You can hold your hand over the right ear cup and it will open up the microphone where you can hear outside noises, which is super convenient for noise cancelling headphones. The only few negatives is that it can only connect to one device, where the QC35 you can setup 2 devices with the phone application. And it's heavier and bigger than the Bose. Other than that these are my daily goto headphones.
