Yes. I love mine. I originally got some bone-conduction headphones to use at my job because I work in a high noise environment and they still work while you're wearing earplugs, but I use them pretty much constantly now. It's really nice to have my music or podcasts and still be able to hear when someone asks me a question, or to be able to hear traffic coming if I'm out walking or jogging.
I've had a couple pairs of them now and weirdly bone-conduction headphones seem to be the one electronic device that under promises on its battery life. I don't know if maybe I just got lucky, but the cheap no name set I got off Amazon promised 5 hours, but even after a year still regularly lasts 8 or 9. My Shokz Open Run Pros promise 10 hours, and I routinely get 15 or 16 hours. So that's nice.
Out of curiosity: did you ever test noise cancelling headsets in that high noise environment? Iโd think that in-ear and over-ear nc headphones should work quite well too.
No, because active noise cancellation doesn't offer any hearing protection. It doesn't make the noise go away, it works by sending out an extra soundwave which is a mirror inversion of noise to be cancelled, sends out peaks where there were troughs and troughs where there were peaks, and they cancel each other out as far as your brain is concerned. But to work the destructive soundwave has to be as loud as the sound it's cancelling, and now you have two sound waves blasting away, still moving air and putting pressure on your eardrums, and it's that pressure causes the damage to your hearing.
Proper PPE has a passive barrier that physically blocks the bulk of the vibration from reaching your eardrums in the first place. Active noise cancellation does kind of the opposite of that.
