FOSETX TH909

Premium Headphones with Urushi Lacquer

The TH909 represents a flagship model among premium headphones, based on the renowned closed-back TH900mk2. While maintaining the same sound characteristics, the open-back design and optimized acoustic circuit further expand and enrich the soundstage.

The TH909 features 50 mm drivers with a 1.5 Tesla repulsion magnet, ensuring precise and dynamic sound reproduction.

Crafted from a blend of bio-cellulose and inorganic fibers, the diaphragm delivers deep bass, natural mids, and exceptional high-frequency presence.

The etched metal grills used for the housing openings diversify resonance points and add a sophisticated aesthetic.

The housing cover is finished with premium Bordeaux lacquer, crafted by the "Sakamoto Urushi Factory," established in 1900 and renowned for its artisanal craftsmanship.

Included is an unbalanced cable made from 7N-grade oxygen-free copper (99.99999% purity), equivalent to model ET-H3.0N7UB.

The headphones are equipped with detachable connectors that support balanced connections using optional XLR cables (model ET-H3.0N7BL). The internal wiring also uses 7N-grade cables to ensure superior quality.

The detachable connectors are finished with rhodium plating, providing high hardness, abrasion resistance, and corrosion resistance.

The newly designed ear pads feature low-resilience cushioning for optimal comfort and maximum audio performance.

The cables for the TH900mk2 (models ET-H3.0N7BL and ET-H3.0N7UB) are also compatible with the TH909, offering flexibility and customization.

The TH909 combines cutting-edge technology with refined design, making it an ideal choice for those seeking excellent audio performance and exclusive aesthetics.
