Crystal sets are the simplest type of radio receiver.
Named for the crystal detector, used to regulate the electrical current emitted by a radio signal, they were simple to construct, inexpensive and required no additional power supply.
However, crystal sets could only receive signals within a small geographic range and listeners needed headphones to hear radio broadcasts.
