Its significantly reduced weight enhances long-term comfort, while improved construction ensures lasting reliability.\nENHANCED MAGNET\nHIFIMAN’s new HE600 uses rare-earth-free permanent magnet materials with a precisely engineered shape that reduces distortion and improves sound clarity. This design achieves sensitivity and control on par with rare-earth magnets, while offering a more sustainable, environmentally friendly approach without compromising the planar magnetic performance HIFIMAN is known for.\n2ND GENERATION NANOMETER THICKNESS DIAGRAM\nAt the heart of the HE600 is HIFIMAN’s second-generation nanometer-thick diaphragm, now just 60% the thickness of the original. This ultra-lightweight membrane further enhances transient response, enabling the driver to reproduce even finer details with greater precision. The reduced mass allows for faster, more accurate movement, translating into improved dynamics, clarity, and immersion. \nIMPROVED COMFORT AND USABILITY\nDesigned for exceptional comfort during extended listening, the HE600 features HIFIMAN’s FocusPad, memory foam wrapped in pleather and soft velour, that gently surrounds the ear for a luxurious fit. An improved 2nd generation headband reduces weight and adds rotatable hinges for easier usability.\nNew 3.5mm connectors, angled at 10 degrees to reduce strain, provide a secure, long-lasting connection between the headphones and cable.\nProduct highlights\n\nEnhanced magnet design using Rare-Earth magnetic materials\nFeatures 2nd generation NEO Supernano diaphragm\nTuning replicates its predecessor, the HE6\nNew composite headband with rotatable hinges and reduced weight\n\nSPECS\n\nOpen-back\nFrequency Response: 8Hz-65kHz\nImpedance: 28 ohms\nSensitivity: 94dB\nWeight: 389g\n","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-he600-planar-magnetic-headphones-1186035331.jpg?v=1761262435","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-he600-planar-magnetic-headphones-1186035329.jpg?v=1761262435","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-he600-planar-magnetic-headphones-1186035328.jpg?v=1761262435","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-he600-planar-magnetic-headphones-1186035327.jpg?v=1761262435","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-he600-planar-magnetic-headphones-1186035326.jpg?v=1761262435","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-he600-planar-magnetic-headphones-1186035325.jpg?v=1761262435","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-he600-planar-magnetic-headphones-1186035324.jpg?v=1761262435","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-he600-planar-magnetic-headphones-1186035323.jpg?v=1761262435","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-he600-planar-magnetic-headphones-1186035322.jpg?v=1761262435","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-he600-planar-magnetic-headphones-1186035321.jpg?v=1761262435","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-he600-planar-magnetic-headphones-1186035320.jpg?v=1761262435","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-he600-planar-magnetic-headphones-1186035319.jpg?v=1761262435","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-he600-planar-magnetic-headphones-1186035318.jpg?v=1761262435","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-he600-planar-magnetic-headphones-1186035332.jpg?v=1761262435","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-hifiman-headphone-hifiman-he600-planar-magnetic-headphones-1186035330.jpg?v=1761262435"],"price":799,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:57.352Z"},"share_url":"https://firestarter.network/l/lst_9r3Iy-X1","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
