HiFiMan’s New Headphone System Has High-frequency Response

• It comes with a sizeable tube amplifier

This new headphone by HiFiMan comes with a pair of electrostatic headphones, which enables sound to be driven by a thin, electromagnetically charged film suspended between two stators with the opposite electromagnetic charge. These stators are rapidly charged and discharged to pull the film back and forth between them, thus generating sound waves.

HiFiMan founder Fang Bian has long had a fascination with nanotechnology (he even has a doctorate in the subject), so the films used in HiFiMan headphones are exceptionally thin: whereas typical films can be a few micrometers thick, those used by HiFiMan are often less than one micrometer thick. This reduces the overall mass of the film, which leads to less distortion and better high-frequency response.

Perhaps the biggest change to the new headphone system is to the size of the included tube amplifier, which has been condensed dramatically when compared to the previous model, especially its height, which has shrunk from 13.4 inches down to just 4.2 inches. It’s also gone on a diet, shedding 11 pounds. However, this downsizing seems to have had little impact on performance; the headphones can still cover a frequency range of 7Hz to 120 kHz when they are plugged into the amp.
