These earmuffs are better than anything I owned for operating noisy machines, and they are quite comfortable (Those designed for shooting are not as good for continuous noise). For example, if I hook or remove the small trailer attached to my diesel lawnmower, I need to stand a few inches away from the muffler. No problem, no discomfort, the noise is very tolerable. You can wear these for a long time without getting tired. For the price asked, this is a cheap price to pay for protecting your ears.
