{"type":"firestarter.listing","listing":{"id":"lst_G7jHrGV2","product_name":"FiiO JadeAudio JT7 Open-Back Planar Headphones","category":"Headphone","description":"Lightweight planar headphones\nThe JT7 brings large-format planar technology into a lightweight, foldable frame that fits easily into daily listening. A 95x86mm proprietary driver, a 3µm diaphragm, a magnetic array designed for high sensitivity, and an ergonomic, serviceable build give you a headphone that delivers planar precision without the usual bulk. It’s straightforward to drive, tuned for clarity and energy, and ready for long stretches of focused listening. \nLarge 95x86mm planar driver\nThe driver is developed entirely in-house, from diaphragm research to the magnetic circuit. This level of control matters. The wide diaphragm area works with uniform electromagnetic force across its surface, reducing sectional distortion and giving the headphone a confident sense of scale. You hear a broader stage, firmer bass, and clean transients that stay stable even at higher volumes. \n3µm ultra-thin diaphragm\nA thinner diaphragm reacts faster to changes in the electrical signal. At just 3µm, the JT7’s film moves with minimal inertia, tracking subtle high-frequency details with ease. Treble takes on a crisp, effortless character, and rapid shifts in dynamics feel immediate rather than blurred. \nF.E.S. elastic system\nThe diaphragm surface includes multi-dimensional texturing that increases elasticity. This added compliance gives the driver more freedom to move while maintaining control of internal stress. Bass gains depth and weight without turning sluggish, and low-level information remains intact even during heavier passages. \nPrecision 28nm manufacturing\nThe JT7 uses a chip-grade fabrication process that integrates the voice coil and diaphragm into a seamless structure. Extremely fine coil traces improve consistency and durability, while the unified construction minimizes mechanical losses. You get stable performance over time, not just on day one.\nTwo-way high-density magnets\nNeodymium iron boron magnets arranged in a two-way layout create a strong magnetic field that dr","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jadeaudio-jt7-open-back-planar-headphones-1210738193.jpg?v=1765390967","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jadeaudio-jt7-open-back-planar-headphones-1210738195.jpg?v=1765390963","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jadeaudio-jt7-open-back-planar-headphones-1210738191.png?v=1765390852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jadeaudio-jt7-open-back-planar-headphones-1210738192.jpg?v=1765390838","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jadeaudio-jt7-open-back-planar-headphones-1210738200.jpg?v=1765390855","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jadeaudio-jt7-open-back-planar-headphones-1210738199.jpg?v=1765390849","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jadeaudio-jt7-open-back-planar-headphones-1210738198.jpg?v=1765390958","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jadeaudio-jt7-open-back-planar-headphones-1210738197.png?v=1765390847","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jadeaudio-jt7-open-back-planar-headphones-1210738196.jpg?v=1765390840","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-fiio-headphone-fiio-jadeaudio-jt7-open-back-planar-headphones-1210738194.jpg?v=1765390843"],"price":120,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:56.770Z"},"share_url":"https://firestarter.network/l/lst_G7jHrGV2","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
