{"type":"firestarter.listing","listing":{"id":"lst_xCZAUzDz","product_name":"SIMGOT EA500 LM","category":"Earphones/IEMs","description":"\nHigh-End 2nd Generation Lithium-Magnesium Dome Diaphragm\nAs an upgraded material for high-quality audio devices, the second-generation lithium-magnesium dome diaphragm combines a flexible suspension system, offering both lightness and stiffness. This material, even lighter than pure beryllium, closely mimics its acoustic properties, providing a nuanced and rapid sound response. The stiff nature of the diaphragm curbs unnecessary vibrations and resonances, ensuring a broad, low-distortion sound spectrum. Compared to its predecessor, the EA500, this diaphragm not only maintains excellent high-frequency clarity but also enhances the richness and fullness of mid to low frequencies, delivering a sound that is both lush and intricately detailed.\n\n\n\n\nThe Second Generation Of Dual-Magnet & Dual-Cavity Dynamic Driver\nBuilding on the EA1000's 2nd-generation DMDC™ technology, the enhanced dual-magnet and dual-cavity design has evolved through meticulous optimization of factors like magnetic circuit structure and volume ratio. This advanced DMDC™ system incorporates both internal and external magnetic circuits, a novel approach that generates a potent effective magnetic flux. This significant enhancement boosts the transient response and expands the bandwidth of the headphones, ensuring low distortion across all frequencies. When compared to its predecessor, this refined system offers superior control over high frequencies. The EA500LM utilizes this sophisticated technology to deliver exceptional dynamics and a profound sense of realism. It stands out for its intricate layering, silky smoothness, and airy feel, coupled with remarkable ductility in the high-frequency domain. \n\n\n\n\n\nAdvanced Tuning and Interchangeable Nozzles\nThe EA500LM encapsulates the essence of acoustic customization and intricate tuning within its compact form. It offers a versatile listening experience through three interchangeable nozzles—each crafted with distinct materials and mixing cloth techniques","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_0047.jpg?v=1705473967","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_0054.jpg?v=1705473969","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_0057.jpg?v=1705473969","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_0034.jpg?v=1705475717","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_0043.jpg?v=1705475717","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_0010_7815b02a-f0c8-4ba7-8053-5a7219707e24.jpg?v=1705475717"],"price":101.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:46.342Z"},"share_url":"https://firestarter.network/l/lst_xCZAUzDz","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
