{"type":"firestarter.listing","listing":{"id":"lst_9N6jfMUQ","product_name":"KZ Merga","category":"Earphones/IEMs","description":"                                            Advanced Dual-Dynamic Driver Technology                        The KZ Merga earphones utilize dual-dynamic drivers to achieve superior sound accuracy. Low-frequency and mid-high frequency sounds are delivered by separate units, ensuring that the deviation from 20Hz to 200Hz is controlled to 8dB or higher, and between 200Hz and 1kHz within 2dB. This precision is unattainable by single-driver earphones, showcasing the superiority of the dual-dynamic driver's acoustic solution.                                                                                    Single-Sided Dual-Driver Configuration                        The KZ Merga features a 10mm super-linear inner magnetic driver for powerful, clear bass, and an 8mm high-performance driver for crisp, detailed mids and highs. An electronic crossover on the PCB ensures accurate frequency separation, enhancing overall sound clarity and reducing distortions. The earphones' skin-friendly resin housing with a transparent black resin cover not only looks sleek but also contributes to superior acoustics, ensuring comfort during extended listening sessions.                                                                                    Superior Engineering for Premium Audio Performance                        The proprietary 8mm driver exceeds the performance of common 10mm dynamic drivers, boasting specifications of 330 impedance and 104 dB sensitivity. This exceptional output highlights our advanced acoustic tuning and research and development capabilities, setting new standards in earphone technology.                                                                                    Professional Electronic Frequency Division                        KZ Merga adopts PCB electronic crossover technology to maximize each driver's performance. This technology optimizes the performance potential within the most suitable frequency range for each driver, ensuring vividly displayed highs","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/b0057737197d71c3bafd506af66f860c.jpg?v=1715421965","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/ecfcf3b11283bde8225e92c4eca084dc.jpg?v=1715421965","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/02aec89dabdb29eadbfa36ac310547d1.jpg?v=1715421965","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/6370e98ec34e03ce1349872e4802ceac.jpg?v=1715421965","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/7_906858ce-927a-43d2-9fa1-944ee39d401e.jpg?v=1715421960","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/8_8ddfbe81-dec7-490b-b889-6155795664f2.jpg?v=1715421960","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/9_dbc69b9e-121d-4e18-9e4f-ccbc7ff68122.jpg?v=1715421960","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/10_16a418a2-cedd-4052-98a0-e2f6eb52a1f7.jpg?v=1715421960","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/3d4408c8738e6ed420e7e514a97a8bf9_8d15f54d-a317-4d7d-9115-a0583a76cabe.png?v=1715421955","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/1_67564082-a404-4d14-8f5e-62bec1d8aac6.jpg?v=1715421956","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/2_32190529-f223-459d-8fe3-af4ae11a6875.jpg?v=1715421955","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/3_c74aa371-8409-4d1c-a9e1-ff9aa7ef40bc.jpg?v=1715421956","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/1_33ba6775-d368-464e-b4ff-c7f4ee446a4e.jpg?v=1715421960","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/2_ddbbe45e-51a1-476b-807d-9ad84eaa8496.jpg?v=1715421960","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/3_2282c215-c292-4044-8942-22f1c4c613b2.jpg?v=1715421960","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/4_c2000fdb-9fc8-4bb4-ba0a-e534b4dec172.jpg?v=1715421961","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/5_f1c578de-6e75-47e1-9b4b-dadcc2fddd03.jpg?v=1715421960","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/6_26fb3300-e68d-4373-85ec-8e8d2a4295f6.jpg?v=1715421960"],"price":12.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:46.194Z"},"share_url":"https://firestarter.network/l/lst_9N6jfMUQ","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
