I bought Bose ANC earplugs a few years ago, having the fantasy of blessed silence amid all the chatter, blaring radio, etc. It was very disappointing. Low level hums are indeed filtered, but the office voices sound even more distinct. Im hoping for AI powered ANC that will be much better at filtering specific annoying voices.
