Piezoelectric earphones also known as crystal earphones or ceramic earphones are the most sensitive devices. They are many times more sensitive than the most sensitive magnetic earphones that you may use. Sensitive earphones have a very high impedance, which is measured in ohms and should not be used directly with a modern amplified radio. Crystal earphones are so sensitive and require so little power to operate that you can hear a small 'click' just by touching the two bare leads together or shorting the jack connector.
Crystal earphones are used in the construction of the crystal radio and in some science experiments.
