{"type":"firestarter.listing","listing":{"id":"lst_1ARJKlxa","product_name":"FiiO FX17","category":"In-Ear Monitors","description":"\n\n\nAdvanced Driver Architecture\nThe FX17 is built with an innovative per-side design featuring one dynamic driver, four custom balanced armature (BA) drivers, and eight high-performance electrostatic (EST) drivers. A meticulously tuned five-way crossover evenly distributes energy among all drivers, ensuring each component operates at its optimal state for a grander soundstage and natural, lifelike audio reproduction.\n\n\nElectrostatic Driver Innovation\nEight carefully implemented electrostatic drivers per side deliver an exceptionally airy high-frequency extension—easily reaching up to 50kHz. Although their inherent sensitivity is only 99dB/mW (compared to the typical 110dB/mW of BA and dynamic drivers), the FX17’s design employs multiple electrostatic units to increase sound pressure levels. This strategic approach overcomes the natural “masking effect” (the ear’s reduced sensitivity to high-frequency sounds in the presence of powerful low frequencies), ensuring that the high and ultra-high frequencies are not only audible but also richly detailed.\n\n\nCustom Balanced Armature Excellence\nThe FX17 features four custom Knowles BA drivers that are innovatively split into composite units—each composed of a dedicated mid-frequency and a mid-high frequency section. This “Midrange Enhanced Balanced Armature Unit,” developed in close collaboration with Knowles, incorporates acoustic vents within the ear cavity to boost sound energy reserves. The result is denser mids and sumptuous, transparent vocal reproduction that places the listener right in the heart of the performance.\n\n\n\nHigh-Fidelity Dynamic Driver Performance\nAt its core, the FX17 utilizes a dynamic driver with a lithium-magnesium alloy diaphragm—a material that is both lightweight and exceptionally rigid. With a density of just 1.6g/cm³, this diaphragm demonstrates high internal damping, minimizing intrinsic resonances and keeping distortion below 0.2%. The result is pristine sound reproduction even at rapid vibratio","images":["https://cdn.shopify.com/s/files/1/0040/7201/3924/files/20250408174428__1.jpg?v=1744105592"],"price":1499.99,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:45.149Z"},"share_url":"https://firestarter.network/l/lst_1ARJKlxa","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
