Description

1、This cable is compatible with the following headphone models (including but not limited to):

• SHURE：SRH1440, SRH1540, SRH1840

To ensure you get the exact product you want, please leave a note with your headphone model and required plug type when placing your order.

2、Technical Specifications & Structure:

This upgrade cable has a standard length of 1.8 meters (approx. 71 inches) and employs an 8‑strand braided construction. Each strand integrates 21 conductors of 26 AWG 6N single‑crystal Silver with 1 graphene‑coated core, delivering 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, 4-pin XLR balanced plug, and 6.35mm stereo 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.

Why Choose 6N Single Crystal Silver?

Single crystal silver features ultra-high electrical conductivity and minimal signal transmission loss.

• Unmatched Transparency and Extension: High frequencies shine like polished crystal, delivering an unprecedented sense of air and radiant luster. The overtones of string instruments and subtle vibrations of cymbals unfold in full detail, creating an expansive and authentic soundstage with distinct boundaries.
• Exceptional Detail Retrieval: The background falls into profound silence, bringing forth those once-blurred musical details— the singer’s faint breath, fingertips gliding across piano keys, and subtle reverberations of the recording space—with crystal clarity, building a vivid and lifelike sonic picture.
• Cohesive & Three-Dimensional Imaging: Instruments and vocals boast a more solid, layered presence with pinpoint positioning and excellent separation. You can practically “see” the exact location of each instrument in space, as if a real band is arranged right before you.

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.
