That's awesome. I actually have a set of ear muffs, different brand. Compared to the Bose QC15's, they let in a lot more bass, where the noise-canceling gets rid of that. Coupling them with earplugs works really well though. They're less comfortable to wear since they squeeze your head harder than headphones (maybe I could adjust mine by stretching the metal headband with two vice's or something), and they have a bit more weight. But for $20 instead of $300, and hack factor, you win hands down! :)
