Through precision engineering of its sealed cavity structure, it effectively resolves the common issue of narrow sound-stage and bass echo often found in closed-back headphones.\nACOUSTICALLY INVISIBLE STEALTH MAGNETS\nUnlike the sound waves created by a conventional magnet, the unique shape of Stealth Magnets enables the waves to pass through the magnets without generating interference.\nHIFIMAN's advanced magnet design is acoustically transparent, dramatically reducing wave diffraction turbulence that degrades the integrity of the sound waves. The reduced distortion yields pure sonic output that is accurate and full-range. \nNEO \"SUPERNANO\" DIAPHRAGM\nThe all new NsD is 80% thinner than previous designs resulting in a faster more detailed response, while retaining lush musicality never before possible. At between 1 to 2 microns thick, the NsD diaphragm sets all be standards.\nNEW BREAKTHROUGH MATERIAL\nBuilding upon the acoustic foundation of the original, the Audivina LE further optimizes earcup shell design through material selection, structural reinforcement, and surface texturing. This minimizes acoustic resonance caused by the housing while delivering a precision-tuned low-frequency boost. Concurrently, the design achieves reduced weight, enhanced long-term wear comfort, and improved structural durability.\nProduct highlights\n\nReference closed-back planar headphones\nFeatures new earcup shell material for better accuracy and structural reinforcement\nAcoustic chamber inspired by the best in theater and concert hall design\nIdeal balance between studio monitoring accuracy and musical enjoyment\nRedesigned headband reduces weight and adds rotatable hinges\n\nSpecs\n\nClosed-back\nFrequency Response: 5Hz-55kHz\nSensitivity: 96dB\nImpedance: 20 ohms\nWeight: 449g\n","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-audivina-le-studio-headphones-1186035364.jpg?v=1761324966","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-audivina-le-studio-headphones-1186035363.jpg?v=1761316981","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-audivina-le-studio-headphones-1186035353.jpg?v=1761316981","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-audivina-le-studio-headphones-1186035356.jpg?v=1761316981","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-audivina-le-studio-headphones-1186035352.jpg?v=1761316981","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-audivina-le-studio-headphones-1186035358.jpg?v=1761316981","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-audivina-le-studio-headphones-1186035357.jpg?v=1761316981","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-audivina-le-studio-headphones-1186035355.jpg?v=1761316981","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-audivina-le-studio-headphones-1186035354.jpg?v=1761316981","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-audivina-le-studio-headphones-1186035351.jpg?v=1761324966","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-audivina-le-studio-headphones-1186035360.jpg?v=1761324966","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-audivina-le-studio-headphones-1186035362.jpg?v=1761324966","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-audivina-le-studio-headphones-1186035361.jpg?v=1761324966","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-audivina-le-studio-headphones-1186035359.jpg?v=1761324966"],"price":399,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:57.355Z"},"share_url":"https://firestarter.network/l/lst_WHLBYtuU","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
