KINGSOUND KS-H3 Electrostatic Headphone Black

How does it works ?

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 have very little diffraction and the volume decreases much less over the same distance.

The electrostatic stereo system is the pinnacle of audio reproduction. The standard upon which all other stereo headphones can be measured.
It literally pushes the limits of the world's most sophisticated instruments that attempt to measure its performance.
The result is an experience that no other stereo system can approach.
The result is an ultra-flat frequency response across the entire range: deep, clean bass with real power that other attempts at electrostatic transducers can only envy.

Le système stéréo électrostatique est le summum de la reproduction audio.
Un système d'écoute professionnel dont la distorsion est infime. Il pousse littéralement les limites des instruments les plus sophistiqués du monde qui tentent de mesurer sa performance.
C'est une expérience que peu de systèmes stéréo peuvent approcher.
Le résultat est une réponse en fréquence ultra-large sur toute la gamme avec un réel pouvoir que d'autres ne peuvent qu'envier.

I use this KS connected to the energizer ifi-audio Pro-IESL and a Tube amplifier. The H3 offers a warm and detailed sound. I've never listened to my (classical) music in such nice and relaxed way. Fantastic Headphone!
