Background A while ago I bought a few hundred of these little earpieces from a … Crystal earpieces are usually monaural devices with very low sound fidelity, but high sensitivity and impedance. Their peak use was probably with 1960s era transistor radios and hearing aids. They are not used with modern portable media players due to unacceptable sound quality. The main causes of poor performance with these earpieces are low diaphragm excursion, nonlinearity, in-band resonance and the very short horn shape of the earpiece casing. The resulting sound is ver…
