Fostex / TH810

Variations

＜＜April 2026 New Product！＞＞The TH810 is a premium standard model headphone developed to deliver the overwhelming resolution and superb sound quality of the flagship headphones TH910/TH919 to a wider audience.

■Acacia Solid Wood Housing Inheriting the Core of the Flagship's Sound
- To achieve the same exquisite tone as the hard maple solid wood housing finished with traditional lacquerware used in the TH910/TH919 housings, but without the lacquerware process, we selected acacia solid wood from among various woods. Acacia, known for its attractive resonance and used in guitars and ukuleles, allows you to enjoy the solid, deep bass and clear, extended treble frequencies inherited from the TH910/TH919.

■Newly Developed 50mm BioDyna Driver
- The BioDyna driver, which has received high praise for its high resolution and extremely smooth sound quality, has been significantly improved. The newly developed edge improves amplitude stability, enabling a tight and controlled expression without excessive bass bloat. Furthermore, by suppressing unwanted resonance, it eliminates muddiness caused by extraneous sounds, resulting in a natural and smooth midrange. Enjoy a high-density, clear, and smooth sound quality that captures all musical information, from tight bass with volume and depth, to transparent and clear midrange and lustrous treble.

■ Lightweight Magnesium Alloy Mechanical Components
- Magnesium alloy is used for mechanical components such as the housing's base plate and hanger, resulting in a 20% weight reduction compared to aluminum alloy. Furthermore, rubber gaskets are used in the rotating mechanism to minimize unwanted vibrations. This design philosophy, paying attention to every detail of each component, has led to improved usability.

■ Newly Shaped Ear Pads with New Materials
- The newly shaped ear pads have a slanted surface that touches the face for optimized comfort. The internal low-rebound urethane has a two-layer structure, with a softer layer on the outside and a highly elastic layer on the inside to conform to the shape of the face. In addition, the use of silk protein synthetic leather, which has three times the durability of conventional materials, ensures comfortable wear even during extended listening sessions.

■ Supple and Comfortable Head Pad and Headband
- The head pad and headband are made of natural sheepskin. This provides a supple and comfortable fit, and you can enjoy the changing texture as you use it.

■ Includes a Unique High-Purity OFC Unbalanced 2-Pole 3.5mm Y-Cable
- The internal wiring and included unbalanced cable utilize 7N (99.99999%) grade high-purity OFC (Oxygen Free Copper) cable, which eliminates impurities to the greatest extent possible to enhance transmission capabilities. Furthermore, you can use the optional 4.4mm balanced cable ET-TH4.4BL2Y or XLR balanced cable ET-TH-XLR2Y.
