{"type":"firestarter.listing","listing":{"id":"lst__KANJjY_","product_name":"Kinera Gramr PRO","category":"Audio Cable","description":"\n\n\nEnhanced Sound Structure\nThe cable structure has been optimized to balance atmosphere and detail, delivering improved low-frequency depth and high-frequency extension. This enhancement expands the vertical and horizontal soundstage, making instruments and vocals more three-dimensional, and ensuring a more accurate and lifelike sound reproduction.\n\n\n\nDetachable Boom Microphone\nEquipped with gold-plated MMCX connectors, the dual condenser boom microphone offers high clarity, excellent sound reproduction, low signal-to-noise ratio, and low distortion. Its internal acoustic design effectively shields ambient noise, enabling high-definition calls and recordings with minimal loss of the original sound quality.\n\n  \n\nInterchangeable Plug Design\nThe Gramr Pro features an interchangeable plug design with an internal 4-pin high-purity metal conductor, minimizing signal loss at the joints. It comes with both a 3.5mm single-ended and a 4.4mm balanced plug, making it compatible with most current HiFi devices and versatile enough to meet various usage needs.\n\n    \n\nPrecision Machined Metal Components\nThe cable’s metal parts are crafted from aluminum alloy and undergo a frosted anodic oxidation CNC finishing process, along with other advanced treatments. These components are highly resistant to corrosion, abrasion, and oxidation. The upgraded Gramr Pro, including the right-side in-ear and boom mic tricone connectors, utilizes the same frosted anodic oxidation CNC finished aluminum alloy, reducing the stethoscope effect caused by unstable wear when using the boom mic.\n\n      \n\nHigh-Transparency Outer Layer\nThe highly transparent soft PVC outer layer guarantees the durability and wear resistance of the in-ear cable. It offers excellent insulation, a soft texture, and high strength, along with superior sealing and anti-seepage properties. The material is resistant to deformation, hardening, and yellowing, even with long-term use.\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/1_1_b5e29510-262c-47a7-a1bf-1bbb77db3832.jpg?v=1723800760","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/2_3648561f-dcf6-41b7-8bca-1010250079f5.jpg?v=1723800761","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/1-3_ed60c496-0fd8-401b-a29d-286d9f13386f.jpg?v=1723801355","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/10_322a8014-c3e7-4328-8faa-2a9fe04d0bd5.png?v=1723801065"],"price":79.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:44.243Z"},"share_url":"https://firestarter.network/l/lst__KANJjY_","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
