{"product_id":"fostex-th909le","title":"Fostex TH909LE","description":"\u003cdiv lang=\"en\"\u003e\n  \u003cp\u003e\u003cstrong\u003eFostex TH909LE\u003c\/strong\u003e is the Limited Edition variant of Fostex's flagship open-back dynamic headphone TH909, available from March 2026. The technical foundation is unchanged from the TH909: the 50mm BioDyna driver with 1.5 Tesla neodymium magnet, Japanese ornamental cherry birch housing with Urushi lacquer applied by Sakamoto craftsmen, double-layer etched metal grille, and low-resilience synthetic leather earpads. The distinction between the TH909 and TH909LE is solely in the accessory package: the LE version omits the headphone stand included as standard with the TH909 — enabling a lower retail positioning while delivering the identical acoustic platform and build quality.\u003c\/p\u003e\n\n  \u003ch3\u003eBioDyna 1.5 T driver with repulsion magnet and open double-grille acoustics\u003c\/h3\u003e\n  \u003cp\u003eThe 50mm BioDyna driver uses a neodymium magnet with a repulsion magnetic circuit at 1.5 Tesla flux density — the same circuit type as in the closed TH900mk2, adapted for the open acoustic chamber through a redesigned acoustic path and tuning. The BioDyna diaphragm in bio-cellulose and composite fibers delivers low specific gravity, high Young's modulus, and high internal loss — translating to fast transient response, rich low frequencies, natural midrange, and an extended high-frequency range reaching 45,000 Hz. The open acoustic chamber uses a double-layer etched metal grille that diversifies resonance points and allows free airflow, widening the soundstage relative to the closed TH900mk2. Frequency response: 5–45,000 Hz, impedance: 25 Ω, sensitivity: 100 dB\/mW, maximum input: 1,800 mW. Weight: approx. 385 g.\u003c\/p\u003e\n\n  \u003ch3\u003eUrushi lacquer by Sakamoto, low-resilience earpads and a stand-free accessory set\u003c\/h3\u003e\n  \u003cp\u003eThe Japanese ornamental cherry birch housing is finished with Urushi lacquer produced exclusively by the Sakamoto Otosho Shoten factory, established in 1900. Over a base black lacquer, several types of silver foil smoked with sulfur are applied in a torn-paper manner — building depth and layering in the finish that makes each individual housing unique. Earpads are low-resilience urethane foam covered in high-grade synthetic leather, conforming to the shape of the outer ear. Included cable: 3 m, 7N OFC, 6.3mm plug, 2-pin connector with rhodium-plated contacts. Balanced connection via the optional XLR cable (ET-H3.0N7BL). The LE version does not include the headphone stand supplied with the standard TH909 — in all other respects of accessories and construction it is identical. Available from March 2026.\u003c\/p\u003e\n\n  \u003ch3\u003eKEY FEATURES\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eOpen-back dynamic design — Fostex TH909 flagship in LE form without headphone stand\u003c\/li\u003e\n    \u003cli\u003e50mm BioDyna driver: bio-cellulose diaphragm, neodymium repulsion magnet circuit, 1.5 Tesla magnetic flux density\u003c\/li\u003e\n    \u003cli\u003eIdentical acoustic platform and build quality to TH909 — difference limited to accessory package only\u003c\/li\u003e\n    \u003cli\u003eJapanese ornamental cherry birch housing with Urushi lacquer (Sakamoto factory, est. 1900) — sulfur-smoked silver foil, each unit unique\u003c\/li\u003e\n    \u003cli\u003eDouble-layer etched metal grille — resonance point diversification, unrestricted airflow\u003c\/li\u003e\n    \u003cli\u003eLow-resilience urethane earpads + high-grade synthetic leather\u003c\/li\u003e\n    \u003cli\u003eIncluded cable: 3 m, 7N OFC, 6.3mm plug\u003c\/li\u003e\n    \u003cli\u003e2-pin connector with rhodium-plated contacts\u003c\/li\u003e\n    \u003cli\u003eBalanced XLR connection via ET-H3.0N7BL (sold separately)\u003c\/li\u003e\n    \u003cli\u003eLE vs TH909: headphone stand not included\u003c\/li\u003e\n    \u003cli\u003eAvailable from March 2026\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eTECHNICAL SPECIFICATIONS\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eType: open-back, over-ear, dynamic\u003c\/li\u003e\n    \u003cli\u003eDriver: 50mm BioDyna (bio-cellulose + composite fibers), neodymium repulsion magnet circuit, 1.5 T\u003c\/li\u003e\n    \u003cli\u003eFrequency response: 5 Hz – 45,000 Hz\u003c\/li\u003e\n    \u003cli\u003eImpedance: 25 Ω\u003c\/li\u003e\n    \u003cli\u003eSensitivity: 100 dB\/mW\u003c\/li\u003e\n    \u003cli\u003eMaximum input power: 1,800 mW\u003c\/li\u003e\n    \u003cli\u003eWeight: approx. 385 g (without cable)\u003c\/li\u003e\n    \u003cli\u003eHousing: Japanese ornamental cherry birch + Urushi lacquer (Sakamoto), double-layer etched metal grille\u003c\/li\u003e\n    \u003cli\u003eEarpads: low-resilience urethane foam + high-grade synthetic leather\u003c\/li\u003e\n    \u003cli\u003eIncluded cable: 3 m, 7N OFC, 6.3mm plug\u003c\/li\u003e\n    \u003cli\u003eCable connector: 2-pin, rhodium-plated\u003c\/li\u003e\n    \u003cli\u003eBalanced cable: XLR ET-H3.0N7BL (sold separately)\u003c\/li\u003e\n    \u003cli\u003eLE vs TH909 difference: headphone stand not included\u003c\/li\u003e\n    \u003cli\u003eAvailable from March 2026\u003c\/li\u003e\n  \u003c\/ul\u003e\n\u003c\/div\u003e","brand":"FOSTEX","offers":[{"title":"Default Title","offer_id":53693019816273,"sku":"59493","price":2027.06,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8741\/0769\/files\/FostexTH909LE1.jpg?v=1778412543","url":"https:\/\/wrdtunes.com\/en-fr\/products\/fostex-th909le","provider":"Wired Tunes","version":"1.0","type":"link"}
