Commentary
Electret stereo headphones.
Connect the wiring of the dedicated adapter to the speaker terminal of the amplifier for use.
The diaphragm is made of highly reliable polymer electret film with excellent moisture resistance and little secular change.
Metal is evaporated on one side of the diaphragm, and the electrostatic shielding effect is applied to the design with low distortion factor.
Non-linear amplitude distortion is eliminated by making the rear fixed electrode concave.
It has a headphone and speaker switching terminal.
