{"type":"firestarter.listing","listing":{"id":"lst_iLfQbeA9","product_name":"SIMGOT EW200","category":"Earphones/IEMs","description":"\n\n\n\nFlagship-level Dual-Magnetic-Circuit & Dual-Cavity Dynamic Driver\nThe EW200 earphones incorporate flagship-level technology in the form of a dual-magnetic-circuit and dual-cavity design, which offer exceptional acoustic performance and a powerful driver configuration. Unlike conventional dynamic driver earphones, the EW200's dual magnetic system uses both internal and external magnetic paths, which are strengthened by N52-grade magnets. This design greatly improves the dynamic range and transient response, resulting in a wider frequency range and a more immersive, detailed listening experience. You'll feel the impact and live presence of the music, as if you're attending a live performance.\n\n\n\n\n\n\nRevolutionary SCP Diaphragm\nThe EW200 utilizes a revolutionary diaphragm material - the SCP Diaphragm. This diaphragm incorporates a special polymer film as a substrate that is coated with a hybrid silicon layer through dual-sided sputtering deposition. By combining the strengths of DLC and LCP diaphragms, it maintains the high-density mid-range performance of LCP diaphragms and the extended, exquisite high-frequency response of DLC diaphragms. Additionally, it overcomes the challenges of high-frequency control and slight harshness found in some audio sources with a DLC diaphragm, resulting in a luxurious and smooth sound with rich layering and spaciousness. The diaphragm is further enhanced through specialized molding techniques and precise material blending, optimized to deliver a full and textured low-frequency response, a natural and dense mid-frequency performance, and a detailed and splendid high-frequency reproduction. With the powerful driving force of the dual magnetic circuit and dual cavities, the diaphragm and magnetic chamber achieve a harmonious balance, thus enhancing overall performance.\n\n\n\n\n\n\nSophisticated Tuning System And Advanced Technology\nThe EW200 is a compact earphone with a sophisticated multi-layer tuning system for precise sound control.
