Since I listen to music/podcasts/audiobooks throughout the day while I'm working, I adapted a pair of normal safety earphones for speakers, and added a vintage look. I cut the outside portion of the cups off, replaced with a curved flat sheet of plastic -over which I mounted the grill (from an old record player) and the cork which I sanded to shape. Then I painted the rest of the shell green, and installed some $50 drivers. I still use them daily.
