This new High Polymer Ultra-Thin Film Material is called Super Engineering Plastics. Super Engineering Plastics is a reinforced and much thinner material than conventional engineered plastics which is used for the diaphragm of the sound element. This and other superior materials have been selected which result in a vast dynamic range, excellent tone quality and frequency characteristics from low to super-high! \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eElectrodes\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNew electrodes called MLER (Multi Layer ElectRodes) have been developed, using ultra-precision photo etch and high tech heat diffusion, 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, high transmissivity of sound wave, and so on. These entirely new electrodes have been completed through the unification of metal plates processed with ultra-procision phtograph etching using the high technology of heat diffusion combination on the atomic level. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eEnclosure\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePrecision Machined Light-Weight Aluminum is used to help realize high-quality sound and rigidity. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eCable\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSilver plated, High Purity Copper Wire 99.9999% (Audiophile Grade) \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eEarpad\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNewly designed, Hand-Crafted Lamb Leather is used for the earpads for hours of comfort. \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eHeadband\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNewly designed 10-click slider mechanism for optimal wear and comfort.
