The ESP/950 Electronic stereophone operates by passing a currentless, electrostatic charge onto opposing capacitor plates which move an intervening, almost mass-less, semi-conductive diaphragm in conformance with the electrical signal from the music source.

The ESP/950 is powered by the E/90 Amplifier which connects to any music source including compact disc and digital audio tape players. The E/90 uses Field Effect Transistors for high input impedance and outstanding signal sensitivity.

The E/90 Amplifier can be powered by either standard household current or the battery pack. For the first time, you can enjoy state-of-the-art audiophile sound in a portable stereophone.
