{"type":"firestarter.listing","listing":{"id":"lst_LFCtix9g","product_name":"Unique Melody  MEST MKII","category":"Earphones/IEMs","description":"\n\n\nAdvanced Dual-Bone Conduction Driver\nUM improved over its Bone Conduction driver they utilized in the OG Mest. For the Mest MKII, they have developed a dual-sided piezoelectric bone conduction driver. Here the driver is placed in between two supporting plates providing a large contact area effectively improving the efficiency and performance of the driver.\n\n\n\n\n\nQuadbrid Driver Configuration With Ultra-Wide Frequency Response\nUnique Melody Mest MKii utilizes a Quadbrid driver configuration with a total of eight drivers per side. The pair features a DD unit, four BA units, two EST drivers, and a Dual-sided Bone Conduction driver. The DD unit produces a powerful lower-end response while the mid and high frequencies are handled by two BAs each. Two EST drivers produce an energetic ultra-high response and the dual-sided Bone Conduction driver provides full-range refinement. Thanks to the highly responsive driver configuration, the frequency response with Mest MKii reaches as high as 70kHz.\n\n\n\n\n\nBeautiful Carbon Fibre Shell\nThe effectiveness of the Bone Conduction drivers depends on the fitting coherence and skin contact. UM has crafted the Mest MKii earpieces using high-quality carbon fiber material. The pair has beautiful looks with carbon fiber and gold foil mixed design on the ear cavities. It also features upgraded metal vents that allow for better air pressure management inside the cavity resulting in better performance with the driver units.\n\n\n\n\n\nHigh-Purity OCC Copper Cable\nUnique Melody Mest MKii comes with a high-quality PVC coated cable. It is made with 4 cores of 24AWG OCC Copper material providing high-grade performance with the pair. Users can also buy it in the 4.4mm termination option.\n\n\n\n\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/products/UMMESTMKII1-1000.jpg?v=1649751318","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/UMMESTMKII3-1000.jpg?v=1649751325","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/UMMESTMKII5-1000.jpg?v=1649751435","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/UMMESTMKII7-1000.jpg?v=1649751657","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/UMMESTMKII9-1000.jpg?v=1649751709","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/UMMESTMKII8-1000.jpg?v=1649752142","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/UMMESTMKII2-1000.jpg?v=1649753944","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/UMMESTMKII6-1000.jpg?v=1649753951"],"price":1499,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:47.576Z"},"share_url":"https://firestarter.network/l/lst_LFCtix9g","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
