Just like when I was a kid
My son recently discovered crystal/trench radios and wanted to try his hand at making one. He asked for a piezo earpiece and this is the one I decided to grab for him. Its just like the one I used when I was his age to make a radio. Worked flawlessly. Grab one and get building a radio!

The voice of the CRYSTAL, still enchanting after 100 years
I build a lot of different types of radios and related stuff. Use these earphones on very basic crystal/fox hole type sets. OK price, decent sound and no issues with any of them.This radio is printed on a FLASH FORGE 3D printer (reviewed on AMAZON), uses coil wire and a germanium diode also from AMAZON. A good ground, a long enough antenna (both with the same coil wire as the coil) and you can listen to local AM broadcasts. No matter how many I make, it is always fun when the static softens and a voice or music is clear. And it is powered purely by the radio waves themselves.
