NOBUNAGA LABS / Hiei Gai NLC-HEI-GAI

＜＜April 2026 New Product！＞＞The "Hiei Gai (NLC-HEI-GAI)" is a replacement cable featuring a 16-core copper-silver alloy conductor that delivers a deep, immersive sound and dignified expressiveness.

■ Copper-silver alloy wire that achieves natural sound dispersion and resonance, extended mid-high frequencies, and well-defined bass.
- To obtain optimal acoustic characteristics, a new conductor is used, combining high-purity oxygen-free copper with silver in NOBUNAGA Labs' unique ratio. Based on high-purity oxygen-free copper, which achieves well-balanced wide-range reproduction from low to high frequencies, silver is combined in a unique ratio to enable clarity and speed, resulting in smooth and transparent mid-high frequencies and well-defined bass. In addition, by using 133 conductors with a diameter of 0.03 mm per core, the conductor resistance value is suppressed and electrical conductivity is improved. The 16-core configuration improves the sense of presence and amount of information, reproducing an even wider range with excellent resolution and a natural, expansive, and rich sound field, while also achieving a more lustrous and extended mid-high frequency and a deep, dignified, and expressive sound.

■ Outer sheath designed for comfortable use.
- High-quality PVC with excellent flexibility and durability is used for the outer sheath. Lightweight, extremely flexible, and easy to handle, this cable offers a comfortable user experience thanks to reduced touch noise.

■ Balanced Connection for Maximizing the Performance of Connected Devices
- Balanced connection uses independent amplifiers for the left and right channels of the player, minimizing crosstalk and enabling more accurate localization and spatial expression. The 16-core braided configuration is designed to maximize the effects of balanced connection.

■ Minimizing Transmission Loss
- By eliminating solder joints (joint processing) at branching points, which cause electrical resistance, and by hand-braiding each cable to equalize the braiding pitch, an ideal design is achieved that does not alter transmission characteristics. The cable's inherent characteristics are fully utilized.

■ High-Quality Japanese-Made Plug
- The 4.4mm 5-pole plug features gold plating on all contact points, providing excellent electrical conductivity. Special treatment is applied to the flash plating process to prevent problems such as plating peeling and oxidative corrosion, ensuring high-level quality over the long term. The plug shell features NOBUNAGA Labs' original matte black design, emphasizing a simple yet luxurious feel.

■ Slim Shell Plug Compatible with a Wide Variety of Headphones
- The plug section, like the player side, uses high-quality Japanese-made components with 24K gold plating, ensuring a stable connection and efficient conductivity. The long shaft and slim shell design allow for compatibility with a wider range of headphone models than conventional cables. (L side is black, R side is red)

■ Molded Construction for High Durability
- The inside of the headphone-side plug shell is molded to minimize problems during cable attachment and detachment. The use of soft and flexible resin reduces stress when the cable is bent.

■ Substantial Splitter Parts
- The Y-split and cable slider feature black anodized aluminum, emphasizing a simple yet luxurious feel. A cable slider is included to ensure secure attachment even when using the cable on the go.
