2、Technical Specifications & Structure:

This upgrade cable has a standard length of 1.2 meters (approx. 47.3 inches) and features an 8‑strand braided construction. Each strand consists of 18 conductors of 26 AWG 5N silver‑plated Oxygen‑Free Copper (OFC) twisted with 1 graphene‑coated core, working together to deliver an exceptional high‑fidelity listening experience.

3、Sheathing & Durability：

The outer sheath is made of high-quality PVC material, which not only offers a skin-friendly and flexible touch but also delivers excellent durability. It can withstand frequent bending and stretching, effectively extending the service life.

4、Connectors & Internal Craftsmanship：

To meet the compatibility needs of a wide range of devices, the cable provides multiple connector options, including: 4.4mm balanced plug, 3.5mm stereo plug, 2.5mm balanced plug. All key internal connection points are soldered with high-grade gold-silver solder to ensure stable and reliable electrical performance and pure signal transmission. Each solder joint is coated with UV resin adhesive for fixation, which can effectively prevent oxidation and detachment of the joints.

Silver-Plated OFC Conductor + Graphene Coating Upgrade Cable | Reconstructing Purity with Science：

• Silver Plating: The “Catcher” of Ultra-High Frequencies

Utilizing silver’s superior conductivity and the skin effect, it precisely captures the most delicate ultra-high-frequency harmonics (e.g., violin overtones, triangle decay) and transient details (e.g., the “click” of a piano hammer strike). This delivers lightning-fast transient response and a transparent sense of air, allowing the edges of the soundstage to bloom naturally like mist.

• OFC Core: The “Foundation” of Mid and Low Frequencies

As the main body of the conductor, high-purity OFC (Oxygen-Free Copper) utilizes its low internal resistance to carry the primary energy and mid-to-low frequency information of the sound (e.g., the chest resonance of a cello, the vocal weight in singing). It ensures a full, warm sonic foundation with rich harmonics, avoiding the “cold and thin” character associated with pure silver conductors. This achieves a balance where details are sharp yet never piercing, and dynamics are powerful yet retain a sense of ease.

Graphene Coating: Resonance Control & Ultra-Fast Conduction:

• Micro-Resonance Suppression:​ The exceptional rigidity and unique layered structure of graphene effectively constrain and dampen microscopic vibrations within the conductors and externally induced resonance. This significantly reduces “coloration” and time-smearing caused by resonance, resulting in cleaner attack and decay, and exceptionally clear, stable imaging.
• Electrostatic Barrier:​ Its excellent conductivity allows for the rapid dissipation of static charges generated from friction, reducing the long-term impact of dust attraction on insulation performance and providing further shielding against external electrostatic interference.
• Aiding Ultra-High-Frequency Extension:​ Theoretically, the graphene coating can provide an auxiliary conduction path for extremely high-frequency signals, working in synergy with the silver-plated conductors to pursue the ultimate in flat, extended bandwidth.
