{"type":"firestarter.listing","listing":{"id":"lst_BS5TPe5V","product_name":"SIMGOT SuperMix 4","category":"Earphones/IEMs","description":"\nInnovative Four-Driver Hybrid Configuration\nThe SuperMix 4 features a luxurious configuration of four different driver types: one dynamic driver (DD), one balanced armature (BA), one planar magnetic driver, and one piezoelectric (PZT) transducer. This carefully constructed four-in-one matrix acoustics architecture allows for precise frequency response adjustment and overall balance. The dynamic driver utilizes a 10mm high-polymer diaphragm to deliver powerful, detailed low frequencies, while the BA, planar, and PZT drivers each contribute to a seamless, unified sound signature, providing an enchanting auditory experience.\n\n\n\n\nHigh-Performance Low-Frequency Dynamic Driver\nSpecially developed for the SuperMix 4, the 10mm dynamic driver boasts a high-elastic suspension system and long-stroke design, combined with a custom high-polymer nano-diaphragm. Through extensive simulation and experimentation, a powerful magnetic circuit system was created. This driver ensures robust and natural low frequencies, enhancing the overall listening experience with rich, immersive bass that integrates perfectly with the BA and other drivers, resulting in a coherent and natural sound.\n\n\n\n\n\nSuperior Mid-Frequency Balanced Armature Driver\nThe large balanced armature driver in the SuperMix 4 stands out for its full-range response and natural tonal quality. Unlike smaller BA drivers that might produce less dense or artificial-sounding vocals, this large BA unit delivers lush, smooth mids and highs with high density and refined detail. It captures subtle nuances such as breath and articulation, making vocals deeply emotive and realistic.\n\n\n\n\n\nHigh-Frequency Planar Magnetic and PZT Drivers\nThe micro planar magnetic driver in the SuperMix 4 covers high frequencies with low distortion and wide bandwidth, offering rich detail and natural tonal quality. Compared to electrostatic drivers, it is easier to drive and enhances high-frequency detail effortlessly. Additionally, the PZT piezoelectric tr","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_5216.jpg?v=1715847035","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_5229.jpg?v=1715847035","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_5233.jpg?v=1715847035","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_5242.jpg?v=1715847035","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_5156.jpg?v=1715847035","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_5247.jpg?v=1715847035","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_5188.jpg?v=1715847035","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_5194.jpg?v=1715847035","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_5199.jpg?v=1715847035","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/IMG_5206.jpg?v=1715847035"],"price":169.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:46.049Z"},"share_url":"https://firestarter.network/l/lst_BS5TPe5V","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
