XoneAudio SOL Mark II Sol God II Monocrystalline Copper Silver Plated Mixed Headphone Upgrade cable

XoneAudio SOL2 Mark II — Flagship Earphone Upgrade Cable

"Wider Dynamics. Deeper Musicality."

The XoneAudio SOL2 Mark II is the second generation of XoneAudio’s acclaimed SOL series, building on the original’s widely praised foundation with critical refinements in conductor composition, insulation architecture, and plug design. By precisely adjusting the ratio of four premium conductor materials — with a significantly increased silver content — the SOL2 achieves a wider dynamic range, more layered musical expression, and enhanced high-frequency extension. Whether paired with classical, pop, rock, electronic, or hip-hop, the SOL2 delivers consistently outstanding sound quality across all genres and IEM brands.

Key Features

• Optimized Quad-Conductor Composition with Increased Silver Content — SOL2 refines the conductor ratio of its four premium materials — monocrystalline gold-plated copper, silver-palladium alloy, and monocrystalline silver-plated copper — with a particular increase in silver content. This is not a simple material upgrade but a carefully calibrated improvement that effectively widens the overall dynamic range, allowing both grand orchestral passages and delicate low-volume details to be reproduced with greater clarity and layering.
• Litz Structure Insulation with Special Intermediate Layer — SOL2 incorporates the designer’s unique interpretation of Litz structure insulation. A special insulating material is embedded between the conductive layer and the shielding layer, maintaining three-frequency balance and stability while significantly enhancing high-frequency extension. Violin overtones, vocal breath details, and instrument air are rendered with exceptional transparency and naturalness.
• Dual-Plated 5N OFC Plug — Gold & Silver — The plug uses 5N-purity oxygen-free copper with both gold-plated and silver-plated finishes on the positive and negative poles respectively. This is not a cosmetic choice — it is the result of dozens of listening comparison experiments with different plating combinations. By matching different signal transmission characteristics to each pole, signal conduction efficiency is further optimized, and sonic detail, resolution, and naturalness are elevated to a new level.
• Exceptional Musicality & Dynamic Expression — The SOL2 excels with music genres that demand wide dynamic range: symphonic music benefits from its expansive soundstage and complex instrument layering; electronic music gains from its powerful, precise bass and rhythmic tension; hip-hop is delivered with strong low-frequency impact and dynamic contrast. Every musical style is fully and faithfully expressed.
• Universal Compatibility — With its balanced, non-fatiguing tuning philosophy, the SOL2 pairs seamlessly with IEMs from different brands and styles. Default configuration is 4.4mm balanced / 0.78mm 2-pin; other terminations available upon request.
• 3-Year Warranty — XoneAudio backs the SOL2 with a 3-year warranty against non-intentional damage, reflecting their confidence in the cable’s build quality and long-term reliability.
