To ensure our driver's performance, a conductive palladium slurry with high temperature resistance is applied to the vibrators, and a pure copper substrate is added on the top of a double-sided ceramic layer. The performance of our bone conduction driver was also optimized by adjusting the internal structure of the cavity. In this way, our driver is more stable and the vibration sense is more comfortable.\n\n\n\n\n\nFrequency Shift Technology\nThe Multiverse Mentor features the frequency shift technology. The hearing frequency range of the human ear is usually 20-20000Hz, with low sensitivity to sounds below 20Hz and above 20 KHz. The frequency shift technology shifts the resonance point of the device to within 2OkHz. The overall sensitivity is significantly improved in the original application environment, and the sound within the 20 to 20000Hz range is mingled in a much more natural way.\n\n\n\n\n\nProfessional Driver Group\nThe UM Multiverse Mentor comes with an independent driver group consisting of four bass, two mids, two mid-treble, four treble, and one frequency shift bone conduction. 5-way crossover design gives each frequency range an independent driver group, with a distinct sound and rich details. In particular, the bone conduction driver has a new Frequency Shift technology, which allows for a more immersive listening experience. The specially designed bass driver mingled with the rigorous frequency gives The Multiverse Mentor a unique sound signature. In the repeated competition between innovation and experiment, we created one of the most characterized products.\n\n\n\n\n\nGorgeous Carbon Fiber Shells\nThe UM Multiverse Mentor comes with advanced aviation-grade carbon fiber shells, with delicate 3D curved Banksia seed faceplates, which are inlaid with an ink-","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1_a98b9ba1-3de0-4242-825d-ceb5eaeb8e4f.jpg?v=1663754749","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/2_9b08b2da-5a1c-4980-9b8e-e2d3611be671.jpg?v=1663754760","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/3_1e4743c4-1176-4323-80c7-7399f3e4ee73.jpg?v=1663754763","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/4_226aac17-a59d-4161-b78b-f07f33d88029.jpg?v=1663754769","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/5_0934a2c9-6d6a-4418-8f75-234103caa732.jpg?v=1663754772","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/6_1b43ca5b-7203-4fa3-aff5-9fa840a2e98b.jpg?v=1663754776","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/7_462d103e-d6cd-48c7-b940-cbd3547f9ac4.jpg?v=1663754782","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/8_4e02c103-d8f2-419b-aa77-00192accbe0d.jpg?v=1663754788","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/9_67c409ed-0d0c-4d41-91b4-227d4b6a6f78.jpg?v=1663754791","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/10_c66e3cda-03cc-4647-b073-32321eeea5d6.jpg?v=1663754796"],"price":4999,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:47.246Z"},"share_url":"https://firestarter.network/l/lst_5IoP1oEw","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
