Crystal sets received radio signals during the earliest days of broadcasting. These simple radios did not operate from batteries or household current-they relied on a semi-conductive mineral known as a crystal and simple circuitry to harness energy directly from radio waves in the air. Crystal sets required a large antenna and a good ground connection to be effective. Due to their low output, crystal sets could not power speakers and listeners wore headsets.
