I really needed a decent pair of noise canceling headphones. The noise canceling part being the most important metric I decided to modify a set of range muffs with a cheap pair of headphones. The result was I can now listen to podcasts while mowing the lawn without cranking my headphones to full volume and doing irreparable damage to my hearing.
This is a good thing and I didn’t have to shell out $300 for the Bose ones that I wanted.
