The copper-silver alloy wire of the COMBINE Series delivers a natural soundstage, rich resonance, and extended mid-high frequencies, coupled with defined low frequencies. To achieve optimal acoustic characteristics, Nobunaga Labs have developed a unique conductor that combines high-purity oxygen-free copper with silver in a proprietary ratio exclusive to NOBUNAGA Labs. This high-purity oxygen-free copper enables a well-balanced wide-range reproduction across all frequencies, while silver enhances clarity and dynamism, resulting in smooth and transparent mid-high ranges alongside defined low frequencies. By employing 133 strands of 0.03mm diameter conductors, Nobunaga minimises conductor resistance, thereby enhancing electrical conductivity. The 8-core architecture improves sound positioning and information density, allowing for the reproduction of an expansive and rich sound characterized by excellent resolution, alongside vibrant mid-high frequencies and profound, expressive low-end sound.

The outer coating is crafted from a high-quality PVC, renowned for its exceptional flexibility and durability. Lightweight and highly supple, it allows for effortless handling and ensures a comfortable user experience by significantly reducing touch noise.

To enhance left-right separation and reduce crosstalk, we have incorporated an 8-core braided structure with a dedicated ground section. This design permits clear sound positioning and spatial expression, even during unbalanced connections, while minimizing distortion in low-frequency reproduction.

The plug on the COMBINE series features high-quality Japanese craftsmanship with 24K gold plating, ensuring a stable connection environment and optimized conductivity. Furthermore, a special treatment post-flash plating effectively prevents issues such as plating peel-off and oxidation over time. The shell showcases NOBUNAGA Labs’ original matte black design, exuding a simple yet luxurious aesthetic.

The connectors are adorned with 24K gold plating to reduce contact resistance and provide outstanding electrical conductivity. Additionally, the shell has undergone precision molding to minimize potential issues during connection and disconnection. The design features NOBUNAGA Labs’ distinctive slit pattern, with black and red lines meticulously printed in the grooves to ensure longevity (black for the left, red for the right).

The Y-branch and cable slider boast a sophisticated black anodized aluminum finish, highlighting a refined yet minimalist appearance. The cable slider is engineered for secure attachment even during movement.
