Fostex TH610 (JPN) Premium Biodyna Closed Back Headphones (Black Walnut)

The housing is made of solid natural wood.
Therefore, there may be differences in grain, bark, coloration, knots, etc. in each item, but this will not affect the sound quality.
Please be aware of this.

Carefully produced at a factory in Japan
Each unit is carefully assembled in limited quantities at a factory in Japan.

Sealed housing carved from solid black walnut
The sealed housing made from solid black walnut wood, whose beautiful grain allows you to enjoy the natural texture of the wood, reproduces a lustrous and natural sound.

BioDyna diaphragm driver containing ultra-fine bio-cellulose fiber material
The in-house driver unit, developed using proprietary technologies accumulated over many years, combines bio-cellulose fiber with other fibers and other materials on the diaphragm under optimal conditions to achieve low specific gravity, high Young’s modulus, and high internal loss. The low distortion rate and ultra-strong magnetic circuit with a magnetic flux density of 1 Tesla and the good linearity of the free edge provide excellent responsiveness and a vast dynamic range over the entire bandwidth, as well as beautiful reproduction of delicate, highly resolved mid and high frequencies, and faithfully reproduces even low mid frequencies with large amplitude.

High-quality and lightweight mechanical parts
Aluminum is used extensively for mechanical parts to achieve a high quality feel and light weight. High specific gravity type resin is used for the baffle plate to reduce resonance noise, resulting in high resolution, rich mid-range, and high-quality bass reproduction.

Detachable connector port
The detachable connector port is made of a rhodium-plated connector terminal with high hardness, wear resistance, and corrosion resistance, and a detachable contact on the headphone body.
The connector port is equipped with a detachable connector terminal and a detachable contact on the headphone body side. Balanced connection is also supported with an optional 4.4mm 5-pole balanced cable (ET-TH4.4BL) or XLR-terminal cable (ET-H3.0N7BL).
The ET-H3.0N7BL is also compatible with balanced connection.

High-purity OFC unbalanced cable included
High-purity OFC (Oxygen Free Copper) unbalanced cables are included, which are free from impurities to the utmost limit to enhance transmission performance.

Soft leather-like high-grade artificial leather pads with low-resilience cushions
The pads are comfortable to wear and provide high sound insulation.
