Improve? Mic, perhaps, but my range and connection reliability have gone down the toilet with a new Macbook air, compared to my pre-USB-c version. I can’t get more than 3’ from it without the audio cutting out. The same headphones can get 100’+ with my iPhone SE.
For what it's worth I have found the NC 700's to have a much better microphone quality when in self voice mode. It's explained here: https://www.gearpatrol.com/tech/audio/a594565/bose-noise-can...
