To those only looking for the noise cancelling component of modern headphones: I was only interested in this as I already have a good pair of (wired, offline) hi-fi headphones, and given some HN comments on this I decided for Peltor x5a passive noise cancelling earmuffs. No batteries to charge and become disfunctional with time, no spy-apps, no potential hearing damage from ANC (not sure what the status is here), no cables, no bluetooth issues; and you get Peltors for 15-30$ so no problem if they break because you stored them in the bottom of a bag. My growing collection of low tech might look a bit dorky but I love it.
