{"type":"firestarter.listing","listing":{"id":"lst_OrUVjVY5","product_name":"FiiO Jade Audio JT1 HIFI Over-Ear Closed-Back Headphones","category":"Headphone","description":"Lightweight driver, heavyweight sound\nMeet the FiiO JT1 — a solid blend of featherweight design and sonic muscle. Featuring a sophisticated PEK+PU+aluminum polymer diaphragm—yes, it’s a mouthful—the 50mm driver is large yet super agile. It dances around those high notes and digs deep on bass, all while keeping distortion low with a brass gasket that's obsessive about precision.\nN52 magnets + CCAW coil\nIt’s like my mom always says: “It’s what’s on the inside that counts, ugly.” And wowza does the JT1 deliver. Armed with super-strong N52 magnets, the JT1 delivers on dynamics and power. Then there’s the CCAW. No, this isn’t the sound a crow makes. It’s a Copper-Clad Aluminum Wire voice coil that provides excellent conductivity for super nuanced audio reproduction.\nEasy to drive - plug and play\nGood audio doesn’t need to be complicated. With its spry 32Ω impedance, the JT1 is as easy to drive as a golf cart. You can hook them up to nearly anything: smartphones, laptops, even your ancient iPod that’s somehow still kicking.\nAdaptive headband for deeply personal listening\nThe JT1 uses a leather-wrapped adaptive headband that magically molds to your head—no manual adjustments needed. Whether you’re vibing to Kendrick or crying to Big Thief, this headband makes every session feel deeply personal.\nCall your grandma\nWhether you're gaming, editing your latest video, or catching up on family gossip, the JT1 has you covered. With its built-in microphone and handy remote control, they seamlessly transition from a private concert to multiplayer mayhem to heart-to-hearts with grandma. No pauses needed. Just smooth sailing from one mode to the next.\nProduct highlights\n\n\n50mm high-performance dynamic driver\n\n\nPEK+PU + aluminum foil composite polymer diaphragm\n\n\nClosed cavity design\n\n\nCCAW paper tube voice coil N52 high performance magnets\n\n\nDual TRS detachable cable\n\n\nInline microphone cable\n\n\nSpecs\n\n\nHeadphone Type: Closed-back over-ear dynamic driver headphones\n\n\nDriver Size: 50mm h","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jade-audio-jt1-hifi-over-ear-closed-back-headphones-40612942577900.jpg?v=1741111327","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jade-audio-jt1-hifi-over-ear-closed-back-headphones-40612942741740.jpg?v=1741111327","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jade-audio-jt1-hifi-over-ear-closed-back-headphones-40612942905580.jpg?v=1741111327","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jade-audio-jt1-hifi-over-ear-closed-back-headphones-40612942708972.jpg?v=1741111327","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jade-audio-jt1-hifi-over-ear-closed-back-headphones-40612942971116.jpg?v=1741111327","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jade-audio-jt1-hifi-over-ear-closed-back-headphones-40612942545132.jpg?v=1741111328","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jade-audio-jt1-hifi-over-ear-closed-back-headphones-40612942807276.jpg?v=1741111328","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jade-audio-jt1-hifi-over-ear-closed-back-headphones-40612942512364.jpg?v=1741111328"],"price":73.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:58.461Z"},"share_url":"https://firestarter.network/l/lst_OrUVjVY5","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
