Key Features：

1. 6N Silver-Plated Copper + Silver Foil Stranded Cable – 4 Strands, 252 Cores – Pure copper cable provides thicker mid and low but slightly darker high; pure silver cable offers brighter high but possibly thinner mid. 6N silver-plated copper + silver foil stranded cable balances the two – taking into account both resolution and musical sensation.

2. "DarkJade" – Named After Ancient Ritual – A reference to the Zhou Ritual, "To worship the northern direction with DarkJade." "Dark" is a metaphor for the profound resonance of sound – ancient jade symbolizes the harmony of sound waves. Like jade in tradition, the cables embody a quiet, silken warmth.

3. Deep Black Copper – Refined Aesthetic – Sleek, deep gunmetal gray base hue for a refined aesthetic. A sophisticated, understated look that complements any earphone design.

4. Self-Built Professional Wire Factory – Acoustic-Grade Material Laboratory – Self-developed procurement of conductors – precise control of coating thickness and crystalline structure, balancing conductivity and ductility to ensure zero distortion. Exclusive tuning of wire impedance and capacitance parameters – matching different headphone units to unleash extreme sound quality potential.

5. Precision Manufacturing – Acoustic-Grade Dust-Free Workshop – Full process adopts acoustic-grade dust-free workshop – from conductor drawing, insulation layer extrusion to shielding layer weaving – all controlled with micron-level precision. Gold-plated plug after 100,000+ insertion and extraction tests – plating layer thickness over 5μm – corrosion-resistant life over 3 times industry standard.

6. Acoustic Engineer Customized Service – Team led by acoustic engineers with more than 10 years of experience – providing in-depth customization from wire impedance matching, crossover frequency optimization to sound field tuning. Adapts to more than 95% of HiFi headphone models on the market – so each pair of headphones can find the best listening experience.

7. Multiple Plug & Connector Options – Available in 3.5mm or 4.4mm plugs with QDC, 2PIN 0.78mm, or MMCX connectors. Widely compatible with most mainstream detachable earphones.
