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, showcase 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, enhanced 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.
