Homemade High Impedance Crystal Radio Headphone from Chili Cans

This video is about how to manufacture a high impedance crystal radio headphone from chili cans and other common household items. Get rid of that old piezioelectric ear bud and replace it with something you made yourself! Impress your friends with sound that comes right out of the air - no batteries! I experimented for years to come up with this simple, elegant design. As you will soon see, it is easy to build and the sound quality is awesome.
