UM Mest brought us the advanced Bone Conduction Driver system, the MKII here improves over it with a newly developed dual-sides Bone Conduction Driver System. The pair in total houses eight drivers per side arranged together in a five-way crossover system for uninterrupted sound performance.\n\nAdvanced Dual-Bone Conduction Driver:-\n\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\nQuadbrid Driver Configuration With Ultra-Wide Frequency Response:-\n\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 re","images":["https://cdn.shopify.com/s/files/1/0031/0453/8673/products/unique-melody-mest-mkii-earphone-hifigo-432376.jpg?v=1670834145","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/unique-melody-mest-mkii-hifigo-262975.jpg?v=1622173193","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/unique-melody-mest-mkii-hifigo-570492.jpg?v=1622166158","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/unique-melody-mest-mkii-hifigo-198547.jpg?v=1622173275","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/unique-melody-mest-mkii-hifigo-625249.jpg?v=1622173244","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/unique-melody-mest-mkii-hifigo-711971.jpg?v=1622173281","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/unique-melody-mest-mkii-hifigo-512968.jpg?v=1622173298","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/unique-melody-mest-mkii-hifigo-829005.jpg?v=1622173334","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/unique-melody-mest-mkii-hifigo-393558.jpg?v=1622173292","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/unique-melody-mest-mkii-hifigo-456532.jpg?v=1622173250"],"price":1499,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:31.420Z"},"share_url":"https://firestarter.network/l/lst_pVyjQf9m","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
