{"type":"firestarter.listing","listing":{"id":"lst_2_sBHdq_","product_name":"KZ ZNA","category":"Earphones/IEMs","description":"\n\n\nSuperb sound in all frequency\nThanks to the combined effort of a dynamic and BA driver, ZNA offers pure music that sounds just as they are made. Efforts are made in the circles’ design, for each driver to be assigned to play to their strength in handling sound in each frequency range. Combined with the natural tuning done by skillful experts, you will easily be immersed in the music with ZNA.\n\n\n\n\n\nWide Sound with 12mm dynamic driver\nAs in every other scenario, size matters. The diaphragm, like your eardrum, helps transmit sound in the form of vibration, so a diaphragm as big as the 12mm one in ZNA prevents the compression feel, and gives you a wider sound. Not only that, but ZNA’s dynamic driver also has dual cavities made possible by two magnetic circles. The magnet gap of them is only 0.15mm wide, which is impossible to make for many companies and gives you so much more details in the music.\n\n\n\n\n\n30095 BA for Analytical Music\nThe strength of the BA driver is transient response and treble, meaning the high-frequency will be more enjoyable and clearer to you. And to compensate dynamic driver’s unsatisfying performance for ultra-high frequency, KZ equipped ZNA with the customized 30095 BA. This KZ-made BA driver can bring the timbre of treble over 2kHZ to a new level. No more jarring high-pitch noise for you, only enjoyable melodies you can relax to.\n\n\n\n\n\nLightweight and Environmental-friendly Beauty\nOnly a high-quality exterior can match ZNA’s excellent inner strength. A dense alloy was chosen to be melt-casted for the protection it can offer for the headphone. This metal case is then embedded with resin lines and a back chamber, representing the strength and purity of the audio you will get. Environmental concerns are also taken into consideration, as the ZNA will arrive at your door in simple wrapping to cut down on plastic used.\n\n\n\n\n\nFirm and comfortable for Your Ear\nZNA is designed to suit your ear canal, thus can sit tightly but not cause you any discomfort.","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/products/97247b9cabd72c62089afd32fffca6e0_71e17f3a-efbd-44a1-908f-3c2a9d26bf4c.jpg?v=1671009437","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/d8148d9af6acfd21463d3ceb1673fa95_34648fc5-4280-43f9-a06f-1eae6ed93a24.jpg?v=1671009448","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/1_bdda3ecd-955c-42a8-b484-8624299f9295.jpg?v=1671009471","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/2_ccc0582c-9047-4fb1-9a1f-9c5218087cde.jpg?v=1671009500","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/3_d63257e7-60b9-4312-b360-14585517c403.jpg?v=1671009503","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/5_e8a69121-b4d3-4d8d-92c4-52ed5cfd3afa.jpg?v=1671009616","https://cdn.shopify.com/s/files/1/0040/7201/3924/products/4_2486e13c-e71e-4865-8381-649e8278b08c.jpg?v=1671010510"],"price":23,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:47.086Z"},"share_url":"https://firestarter.network/l/lst_2_sBHdq_","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
