If your perfect pair of headphones has finally cracked beyond repair, not all is lost: blogger Ean Golden discovered that he could make his headphones live on with a $20 pair of noise-isolating earmuffs.
We've seen lots of hacks like this before, but this one's a bit more involved—and produces better sound quality. Instead of turning a crappy pair of headphones into noise-isolating ones, Ean took the drivers out of his old, broken Sony MDR-V700and built them into a pair of industrial earmuffs from the Ear Plug Superstore. The result? High quality sound with complete and utter isolation from the outside world.
It'll take some tools and bravery to get it done, but overall it isn't the hardest thing in the world. Be prepared for a slightly different sound, too, since you're putting the drivers in an entirely new casing, but $20 to save an expensive pair of headphones isn't a bad gamble.
