Premium headphones made in Japan with traditional lacquer coating

High-end sealed headphones with the most acclaimed lacquered housing in the history of Fostex headphones. The lacquer Bordeaux-finished housing satisfies the pleasure of ownership along with high quality sound.

These high-end sealed stereo headphones feature a newly developed driver unit with a magnetic flux density of 1.5 Tesla, a BioDyna diaphragm, and a 7N (OFC) cord with an optimized wire diameter.

How the TH900 lacquered housing is made

Features

Lacquer, Bordeaux finish

The housing cover features a beautiful lacquer Bordeaux finish by Sakamoto Otozou Shoten, a company that has been in business for 110 years.
The housing cover is a fusion of traditional craftsmanship with a premium feel that is worthy of the “Made in Japan” brand.

High-grade wood "Mizume Cherry" is used.

The housing is made of mizumezakura, a high-grade wood with a fine, hard texture and beautifully finished surface.

Extensive dynamic range

Magnetic circuit employing a repulsive magnetic field is equipped with a 50mm driver unit with a magnetic flux density of 1.5 tesla.
The low distortion rate and ultra-strong magnetic circuit provide a vast dynamic range.

Sound reproduction with excellent presence

The diaphragm is made of “BioDyna”. It realizes a rich sound in the ultra-low range, a straightforward mid-range, and a reproduced sound with excellent presence especially in the high frequency range.

What is bio-cellulose fiber?
Biocellulose fiber is made by advanced biotechnology and is an ultrafine fiber with a thickness of 20 to 50 nm (nanometers), which is 1/1000th of natural plant fibers (e.g. cotton). These fibers are extremely pure α-cellulose, with almost no harmful impurity components, and exhibit the highest level of crystallinity. The ultrafine bio-cellulose fiber has excellent reproduction ability in the mid and high frequencies. When various fibers are combined with this fiber in an appropriate blend, a sound quality that combines the characteristics of each fiber can be obtained, enabling sound creation of a higher level. We have established a technology for mass-producing high-performance diaphragms by blending bio-cellulose fibers with other fibers under optimal conditions, utilizing the know-how we have accumulated over many years.

Carefully Selected Ingredients

Unbalanced cable (ET-H3.0N7UB) with 7N grade (99.99999%) high-purity OFC (Oxygen Free Copper) cord is included as standard.
The plug sleeve is made of highly durable duralumin.

Lightweight earpads

Protein leather and low-resilience cushions are used for ear pads.
Egg-derived protein is blended into the earpads for a pleasant feel and comfortable fit.
In addition, they are 60% lighter than genuine leather.
