Piezo Earphones are not used with modern electronics due to unacceptable sound quality. The main causes of poor performance with these earpieces are minimal diaphragm movement, nonlinearity, in-band resonance and the short horn shape of the earpiece casing. The resulting sound is very tinny and lacking in bass.
In addition, this New Design Magnetic Coil High Impedance earphone is much more reliable than the more common Piezo element earphones with an aluminum diaphragm.

High impedance earphone attached to a circuit board with Integral Male Plug Connector.
Designed for use with Mono Output crystal radios but may also work with many other electronic devices.
