In Detail
Equipped with in-house crafted driver units from the TH900 series.
The proprietary in-house driver unit, crafted from technologies honed over numerous years, blends bio-cellulose fiber with various other materials on the diaphragm.
This meticulous combination, under optimal conditions, results in a diaphragm with low specific gravity, high Young's modulus, and superior internal loss
Utilizing a repulsive magnetic circuit with neodymium magnets, the 1.5 Tesla ultra-strong magnetic circuit delivers exceptional responsiveness and an expansive dynamic range across all frequencies.
This design enables the reproduction of exquisite mid-high frequencies with detailed resolution, while also faithfully capturing the rich low mid-range with significant amplitude.
Ingenious open housings made of solid black walnut and aluminum
The housings, crafted from premium solid black walnut, showcases a distinctive design. Its open aperture, coupled with a dual arrangement of etched aluminum components, offers varying impressions depending on the light and viewing angle.
The carefully calibrated aperture ratio and precise fine-tuning of each internal component, en-hanced by the resonance of the solid black walnut wood, result in a natural sound field that offers a comfortable and fatigue-free listening experience.
TH808 original high-purity OFC unbalanced cable included
It comes with TH808's exclusive high-purity OFC (Oxygen Free Copper) unbalanced cable, free from impurities, ensuring optimal transmission performance.
Detachable connector port and 7N grade cable for internal wiring
The removable connector on the headphone body, as well as the detachable connector terminal, are both rhodium-plated terminals.
Rhodium plating is renowned for its durability, resistance to wear, and ability to protect against corrosion.
Achieving a balanced connection is possible with the use of an XLR-terminal cable (ET-H3.0N7BL), which is available for separate purchase.
Ear pads with low-resilience cushions
The detachable headphone connection terminals are rhodium-plated to enhance hardness, abrasion resistance, and corrosion resistance, ultimately boosting their reliability.
