At its core is a 10 mm liquid-crystal-polymer (LCP) dynamic driver—lightweight yet rigid—that delivers rich, impact-driven bass and extends cleanly into the treble with total harmonic distortion kept below 1%.\n\n\nRobust, Responsive Bass\nFiiO’s asymmetrical internal-and-external magnet circuit increases magnetic flux around the voice coil for tighter transient response and higher output—so every drum hit and sub-bass rumble hits with authority, while preserving detail in mids and highs.\n\n\nBuilt-In DSP & Presets\nThe USB-C version houses an independent DSP audio chip with native support for up to 96 kHz/24-bit decoding. Five onboard sound profiles (Default, Bass Extension, Treble, Vocal, Harman Reference) let you tailor the JD1’s signature via “+” and “–” buttons on the inline remote.\n\n\nUniversal Plug-and-Play\nChoose between a 3.5 mm jack or USB-C connector: both are truly plug-and-play on iOS, Android, Windows, and Mac. The included cable’s HD mic and three-button remote handle calls, playback, and volume without extra adapters.\n\n\nComfort-First Design\nEach 7 g earpiece features front-rear cavity pressure relief to reduce eardrum strain and an ergonomic, triangular shape that stays secure through long listening sessions. Aluminum-alloy nozzles provide consistent sound transmission and durability.\n\n\nPremium Build & Future Upgrades\nHand-polished, die-cast zinc-alloy faceplates lend the JD1 a refined look and feel rare in entry-level IEMs. The 0.78 mm dual-pin detachable cable lets you swap in aftermarket cords to unlock even greater sonic potential.\n\n","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/3.5Bl_9d26ba4d-495e-4f4b-8da0-4c69c26c06c3.jpg?v=1745398372","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/TypeCBl_755dc1a0-b092-4185-9f09-952f8724a0b3.jpg?v=1745398410","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/3.5W_5fb361a4-7b36-401c-a380-91a04f96fba2.jpg?v=1745398410","https://cdn.shopify.com/s/files/1/0040/7201/3924/files/TypeCW_a97ac593-7a02-408a-ae5f-aeeb06b08be2.jpg?v=1745398372"],"price":15.99,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:45.112Z"},"share_url":"https://firestarter.network/l/lst_o7-ACTrI","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
