These work as capacitor microphone except a permanent (electrostatic) charge applied to microphone during manufacture removing need for phantom power. However the diaphragm requires a larger mass to hold the electrostatic charge adversely effecting frequency response. Electrets tend to be cheap, compact and easy to mass-produce.
