The Fostex TH919 is the next-generation flagship open-back headphone from Fostex, advancing the legacy of the acclaimed TH900 series. Since its release in 2012, the TH900 series has been Fostex's flagship model, captivating many audio enthusiasts with its unique BioDyna driver's superb sound quality and the unparalleled texture of its beautiful lacquered housing. The TH919 inherits these charms while completely revamping everything from the driver and housing to the structure, evolving into the next generation. Sporting a solid maple wood housing with a distinctive Japanese Urushi lacquer finish, the TH919 is as much a tool as a work of art — combining traditional Japanese craftsmanship with cutting-edge acoustic engineering for an immersive, natural, and highly detailed open-back listening experience.

Key elements of its design:

• Newly Developed 50mm BioDyna Driver The BioDyna driver, acclaimed for its high resolution and extremely smooth sound quality, has been significantly upgraded. A newly developed edge improves amplitude stability, enabling tight and well-defined low frequencies without excessive expansion, while suppressing unwanted resonance to eliminate muddiness and achieve a natural, smooth midrange.
• Kumiko-Inspired Open Housing The open-type TH919 uses aluminum finished with matte anodizing based on a geometric pattern inspired by "Kumiko" woodwork on the housing opening, with a precise two-layer structure using laser-cut mesh and meticulous adjustment of the aperture ratio and internal components — reproducing a natural sound field with high resolution and minimal listening fatigue.
• Urushi-Lacquered Maple Housing The solid maple wood housing carries a distinctive traditional Japanese Urushi lacquer finish, uniting the precision of the driver with the artistry of handcrafted Japanese lacquerware.
• Lightweight Magnesium Construction Newly adopted magnesium alloy mechanical parts in the housing base plate and hanger help reduce the weight of these headphones by 20% compared to aluminum components, for superb long-session comfort.
• Premium Materials Throughout The earpads use silk-protein material, while the headband and cushion are finished in natural sheepskin leather, delivering an intentionally light clamp force for fatigue-free extended listening.
• High-Purity Detachable Cable The detachable headphone cable is made from 7N-grade high-purity OFC (oxygen-free copper) for enhanced transmission, terminating in a gold-plated ¼" TRS connector, with 3.5mm TS connectors at the earcups for improved recabling compatibility. An optional 4.4mm balanced cable is available.

Reviewing the TH919, Headphonecheck noted that although open-back in design, it delivers impressively strong bass — even more controlled and resonance-free than the closed-back TH910 — with sub-bass that remains taut and detailed, never bloated, revealing subtle textures across genres from EDM to classical.
