Heard a younger guy in a shop in Tulsa raving about those earmuff style Bluetooth muffs with a built in mic. Figured he was just spoiled, but I tried a pair while running a dyno pull last Tuesday and could actually hear the knock sensor tone over the noise. Anyone else running active noise cancelling muffs, or is it just another gadget that gets lost by Friday?
I remember being at a family reunion maybe five years back and watching my uncle put in foam earplugs just to get away from the noise of twenty people talking at once. He sat there smiling with a glass of tea, and that stuck with me. It hit me later that most folks don't use sound gear for fancy work stuff, they use it to find a little quiet in a world that never shuts up. So these muffs with mics, they're not just for shops. They're part of a bigger thing where we're all just trying to pick out the one sound we need without losing our hearing to everything else. If they let you hear that knock tone, that's your quiet, and I bet that young fella found his somewhere else entirely.
