I also use the Bose QC35 very regularly. I'm a software engineer and wear them 6ish hours a day when I'm working, and I've started wearing them in my shop most of the time. They do a good job of reducing the noise from power tools, enough so that I can run any tool (even my super loud porta-band) comfortably. I'm frequently listening to a book or podcast or music when I'm in the shop, though sometimes I just have on the noise cancelling with no audio so the headphones act as very comfortable ear protection.
