By using 133 ultra-fine high-purity oxygen-free copper wires of 0.06mm per core, conductor resistance is suppressed and electrical conductivity is improved. Realizes a natural and lively mid-low range. In addition, the tin-plating process gives the sound a rich reverberation and thickness, and realizes a vivid and extended high range and a dense sound with a solid and excellent response. By rounding the conductor, the flexibility and durability of the conductor itself are dramatically improved. It acts as a stable signal transmission even when exposed to bending and sudden temperature changes.

The symmetrical braid matrix, which makes the twisting direction of the positive side and negative side of the conductor symmetrical and smoothes the flow of electrical signals to the limit, suppresses the increase in electrical resistance between conductors and provides a wide band from low to high frequencies. Allows sound to be transmitted.

Balanced connections use independent amps for the left and right sides of the player, minimizing crosstalk and enabling more accurate localization and spatial expression. The 4-core braided configuration is designed to maximize the effect of balanced connection.

In order to equalize the weaving pitch of the cables, we have achieved an ideal design that does not change the transmission characteristics by hand weaving one by one without soldering the branches (joint processing), which causes electrical resistance. The original characteristics of the cable are fully exhibited.

The 4.4mm 5-prong plug is gold-plated on all contacts for excellent electrical conductivity. By applying a special treatment to the flash plating process, problems such as plating peeling and oxidation corrosion are prevented, and high-dimensional quality is achieved over the long term. The plug shell adopts NOBUNAGA Labs’ original matte black design, which emphasizes a simple yet luxurious feel.

Like the player side, the plug part uses high-quality Japanese-made 24K gold plating to achieve a stable connection environment and efficient conductivity. In addition, the long axis and slim shell specifications make it compatible with a wider range of models than conventional headphone cables. (L side is black, R side is red)

The inside of the plug shell on the headphone side is molded to minimize troubles when connecting and disconnecting the cable.

In addition, by adopting a soft and supple resin, it reduces the burden when the cable is bent.

Uses WBT lead-free silver solder that draws out high resolution. It has a high response and good crispness, accurately depicts the outline of the sound, and expresses even the finest sounds realistically.

The Y-branch part and the cable slider are treated with black aluminum anodized aluminum, emphasizing a simple yet luxurious feel. A slider is used to reduce cable wobble even when used on the move.

-156 ℃ / 72 hours of unique cryo treatment removes the distortion of the molecular arrangement, suppresses the electrical resistance value, reduces noise and distortion, and achieves a clear and three-dimensional spatial expression and an excellent S/N ratio. Allows for rich sound.
