Crystal Earphone (Piezoelectric)
Product Code: CH905ST

Piezoelectric earphones also known as crystal earphones are the most sensitive earphones. In fact they are at least 10 times more sensitive than very sensitive magnetic earphones, dynamic earphones, and electrostatic earphones. Sensitive earphones have a very high impedance, which is measured in ohms.

Crystal Earphones are used in the construction of the crystal radio and in some science experiments such as listening to electric fish.
