Don't forget the amp to drive them too.  You must use an electrostatic headphone amp to drive electrostatic headphones, you may not use a traditional amplifier. It will not work.  Moon Audio has some bundles below so you can add the amp at now and save $.

"In my view, the combination of the KS-H3 headphones and the M-20 OTL tube amplifier/energizer bring a new level of transparency and musical enjoyment to headphone listening.

They are highly resolving, superbly balanced and wonderfully musical devices that will provide years of blissful music listening and gratification to those who are fortunate enough to own them," Frank Alles, Stereo Times Review.

Moon Audio is excited to be able to introduce the King Sound KS-H3 headphones.   Moon Audio has included a description of the technology behind Electrostatic headphones and loudspeakers below.  

How do Electrostatic headphones and speakers work?
The electrostatic loudspeaker is very simple in concept, but difficult to construct successfully in practice. lts operation relies on electrostatic attraction and repulsion, in much the same way as a piece of thin paper attracted to a rubber balloon that is charged by rubbing it against fabric.

The electrically charged ultra-thin conductive film diaphragm is tensioned and placed close between two metal grids. When a high voltage audio signal is applied to the metal grids, the diaphragm moves in response to the signal, moving towards the grid which at that instant is oppositely charged, and away from the grid which has the same charge as the diaphragm. The diaphragm responds in an essentially linear manner, producing sound waves which are a very accurate reproduction of the original sound.
Why is it better?
Imagine a normal speaker as a point source, from which the sound waves produced diffract at a great angle. This causes rapid decrease in volume and quality over a short distance. 

Then imagine a flat electrostatic panel producing sound from the same input signal. This time the sound waves are produced over a large, flat area, therefore they have very little diffraction and the volume decreases much less over the same distance.
