It was almost a year after diagnosis, I think, before I picked up a $20 pair of shooting earmuffs to cut down on the sound of the world around me when out and about. To this day, I’ve not tried out a pair of actual noise-canceling headphones, but this has me wondering if I’m missing out on something I actually need or if in fact I’m fine with what I have. It’s not lost on me that there’s a large cost differential between a $20 pair of shooting muffs and a piece of electronics that costs $100, $200, $300, or more, depending.
