As someone with misophonia I wear noise canceling headphones at all times at work. Somehow my office mates are constantly eating, sniffling, grunting, coughing or loudly talking. At least I can block out most of that with music, but I'd really like to be capable of interacting with my co-workers more naturally. I have to get up and walk away on my own a lot to make sure I don't snap. Wearing headphones 24/7 also makes my head sore and often gives me headaches.
