Features
Lacquer finish in Bordeaux
Featuring a beautiful “lacquered Bordeaux finish” housing cover crafted by Sakamoto Otsuzo Shoten, a company with 110 years of history.
It delivers a premium feel befitting a Made in Japan product that blends traditional craftsmanship.
Made with premium "Mizume cherry" wood
The housing is crafted from premium “Mizume-zakura” wood, renowned for its fine, dense grain, exceptional hardness, and beautiful surface finish.
Extensive dynamic range
The magnetic circuit with a repulsive magnetic field incorporates a 50mm driver unit with a magnetic flux density of 1.5 tesla.
It delivers an expansive dynamic range through its ultra-powerful magnetic circuit with low distortion.
Sound reproduction with outstanding presence
The diaphragm employs “Biodyna” technology. It delivers rich sound in the ultra-low frequencies, a natural midrange, and, for the high frequencies, achieves reproduction with particularly excellent presence.
— What is Bio-Cellulose Fiber? —
Bio-cellulose fiber is produced using advanced biotechnology. Each fiber is 20–50 nm (nanometers) in diameter, making it an ultra-fine fiber approximately 1/1000th the thickness of natural plant fibers (such as cotton). This fiber is highly pure α-cellulose, containing almost no harmful impurities and exhibiting the highest level of crystallinity.Ultra-fine bio-cellulose fiber possesses exceptional capabilities for reproducing mid-to-high frequencies. Combining it with various other fibers in appropriate blends allows for sound quality that combines the characteristics of each fiber, enabling the creation of sound at a significantly higher level. Leveraging our expertise accumulated over many years, we have established technology to mass-produce high-performance diaphragms by blending bio-cellulose fiber with other fibers under optimal conditions.

Includes high-purity OFC unbalanced cable
It comes with a high-purity OFC (Oxygen-Free Copper) unbalanced cable rated at 7N (99.99999%) grade, which maximizes transmission capability by eliminating impurities to the utmost degree.
Achieved lightweight ear pads
The ear pads feature protein leather and low-rebound cushioning.
Incorporating egg-derived protein delivers a pleasant feel against the skin and comfortable fit.
Additionally, they achieve a 60% weight reduction compared to genuine leather.
