With updated drivers, pads, and other housing pieces, the SR-009S is a step forward while still retaining much of the character of the original. \u003c\/span\u003e\u003cbr\u003e\u003cmeta charset=\"utf-8\"\u003e\u003c\/p\u003e\n\u003cp\u003eJapanese manufacturer STAX have been developing headphones since 1938 and electrostatic headphones since 1959. Utilising electrostatic technology in their ‘earspeakers’ that are widely regarded as the best headphones available today, STAX electrostatic earspeakers are widely used throughout the world by discerning audiophiles, professional musicians, and recording companies to enjoy and monitor sound thanks to the superb sonic quality that they offer.\u003c\/p\u003e\n\u003cp\u003eAn electrostatic transducer is a speaker design that employs a high polymer film of several microns thick as the diaphragm for far less mass than paper or mylar cones or metal type diaphragms. Since electrostatic elements use no magnets, they are free from magnetic hysteresis distortion that is prominent in dynamic type headphones.\u003c\/p\u003e\n\u003ch3\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0225\/9777\/files\/stax-sr-009s-headphones.jpg?v=1619651650\" alt=\"stax sr-009s headphones\" data-mce-fragment=\"1\" data-mce-src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0225\/9777\/files\/stax-sr-009s-headphones.jpg?v=1619651650\"\u003e\u003cbr\u003e\u003cbr\u003eTECHNOLOGY AND MATERIAL\u003c\/h3\u003e\n\u003cp\u003eDIAPHRAGM\u003cbr\u003eA newly developed sound element has been adopted in the SR-009S. New high polymer ultra-thin film materials called the super engineering plastics are employed for the diaphragm of the sound element. Materials superior in tone quality have been selected to attain the excellent frequency characteristic from low to super-high as well as the vast dynamic range.\u003c\/p\u003e\n\u003cp\u003eELECTRODES\u003cbr\u003eNew electrodes named MLER (Multi Layer ElectRodes) have been developed to realize the plane drive of the whole film diaphragm surface. While infinite thinness and flatness are required for the fixed electrodes, they simultaneously need to have other characteristics such as low resonance and high transmissivity of sound waves. The entirely new electrodes have been constructed through the unification of metal plates processed with ultra-precision photo etching.\u003c\/p\u003e\n\u003ch1\u003eSpecifications\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan style=\"line-height: 1.2;\"\u003eType: Push-Pull Open Back Circular Electrostatic Headphone\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"line-height: 1.2;\"\u003eFrequency Response: 5 - 42,000Hz\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"line-height: 1.2;\"\u003eElectrostatic Capacitance: 110pF (including cable)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"line-height: 1.2;\"\u003eImpedance: 145k Ω (including cable, at 10kHz)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"line-height: 1.2;\"\u003eSound Pressure Sensitivity: 101dB \/ 100V r.m.s. 1 kHz\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"line-height: 1.2;\"\u003eMaximum Sound Pressure: 118dB \/ 400Hz\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"line-height: 1.2;\"\u003eBias Voltage: 580V DC\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"line-height: 1.2;\"\u003eLeft \u0026amp; Right Identification \u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"line-height: 1.2;\"\u003e\"L\" and \"R\" indicated on the arc assembly (inside head spring)\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan style=\"line-height: 1.2;\"\u003eLeft channel cable is marked with a solid Line.
