Featuring a custom 95×86mm planar driver with an ultra-thin 1μm PET diaphragm and sapphire-aluminum dual coating, the JT9 delivers exceptional resolution, wide soundstage, and natural timbre. With a low 20Ω impedance and 95dB sensitivity, it is easily driven by portable devices while still scaling with higher-end desktop amplification.\u003c\/p\u003e\n\n\u003ch3\u003eCustom 95×86mm Planar Driver\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the JT9 is a \u003cstrong\u003ecustom 95×86mm planar magnetic driver\u003c\/strong\u003e — significantly larger than typical portable-oriented planar drivers. The large diaphragm area delivers powerful, authoritative bass and a wide, immersive soundstage. The \u003cstrong\u003euniform-field magnetic system\u003c\/strong\u003e ensures consistent magnetic flux across the entire diaphragm, minimizing distortion and ensuring accurate, linear response.\u003c\/p\u003e\n\n\u003ch3\u003e1μm Ultra-Thin Diaphragm with Sapphire-Aluminum Coating\u003c\/h3\u003e\n\u003cp\u003eThe JT9 features an exceptionally thin \u003cstrong\u003e1μm PET diaphragm\u003c\/strong\u003e — significantly thinner than the 3μm+ diaphragms found in most conventional planar headphones. This ultra-thin diaphragm enables fast, precise transient response and reproduces subtle high-frequency and ultra-high-frequency signals with exceptional detail. The \u003cstrong\u003esapphire + aluminum dual-layer coating\u003c\/strong\u003e combines excellent electrical conductivity with high rigidity, ensuring the diaphragm moves with precision and control.\u003c\/p\u003e\n\n\u003ch3\u003eLow Impedance, High Sensitivity — Easy to Drive\u003c\/h3\u003e\n\u003cp\u003eHistorically, planar magnetic headphones have required powerful, dedicated desktop amplifiers to sound their best. The JT9 breaks this mold with a highly efficient design featuring \u003cstrong\u003e20Ω impedance\u003c\/strong\u003e and \u003cstrong\u003e95dB\/mW sensitivity\u003c\/strong\u003e. With just 300mW of output power, the JT9 comes alive with dynamic, effortless sound. This makes it an ideal match for portable DAC\/AMPs, smartphones, and laptops, while still benefiting from higher-end desktop amplification for maximum performance.\u003c\/p\u003e\n\n\u003ch3\u003eBalanced, Neutral Sound Signature\u003c\/h3\u003e\n\u003cp\u003eThe JT9 features a \u003cstrong\u003eneutral, balanced sound signature\u003c\/strong\u003e with refined tuning:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBass:\u003c\/strong\u003e Reduced quantity compared to its predecessor, with deeper, tighter extension and excellent control\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMids:\u003c\/strong\u003e Vocals are slightly recessed for a more natural, spacious presentation with excellent instrument separation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTreble:\u003c\/strong\u003e Enhanced detail and harmonic overtone reproduction, with smooth, non-fatiguing extension\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoundstage:\u003c\/strong\u003e Wide, open, and airy with excellent depth and imaging precision\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003ePremium Build \u0026amp; Comfort\u003c\/h3\u003e\n\u003cp\u003eThe JT9 features a \u003cstrong\u003efoldable multi-axis ergonomic design\u003c\/strong\u003e for easy storage and transport.
