Electrostatz Technology


Electro – Dynamic Speakers

  • Ordinary speakers have a cone shape diaphragm typicallymade out of paper, plastic or metal.
  • These are known as electro-dynamic transducers, and they work on electromagnetic principals and basically move air which arrives at your ears as a soundwave.
  • Electro-dynamic speakers are a point source, meaning sound disperses radiallyfrom the speaker’s centre

Electro – Static Speakers (ESL)

  • Electro-static speakers start with a thin, lightweight membrane impregnated with an electricallyconductive material.
  • This membrane, called the diaphragm, is stretched taut between two rigid, parallel, perforated metal plates called stators.
  • The current in the stators varies with the audio signal, the resulting electromagnetic fields push and pull the charged diaphragm, causing sound waves to be produced, which pass through the stators’ perforations.
  • Sound actuallyemanates from the front and rear. This is called ‘dipole’.

Hybrid Design

  • The patented ElectrostatzT” electrostatic technology is capable of reproducing high-frequency sounds up to 45kHz, directly translating electrical audio signals into sound, without distortion or the ‘hysteresis’ effect of traditional dynamic headphones.
  • However, in order to deliver punchy bass, a dynamic cone driver is needed for the low frequencies.
  • The hybrid Electrostatz module was developed and is used in all our headphones.
  • The module can be adjusted when manufactured, much like a cross-over in a loudspeaker. This means different models in our range will be tuned to specific uses.


  • Between 2001 and 2007,a revolutionary new type of electrostatic technology was developed by the Industrial Technology Research Institute, Taiwan’s largest industrial research institute.
  • This new electrostatic technology is Self-Biasing meaning it can work from the tiny current contained in the audio signal.
  • Won the Wall Street Journal Technology Innovation Award in 2009.
  • The core technology was further developed refined and eventually patented as ELECTROSTATZ TECHNOLOGY
