NOBUNAGA LABS / NLASRE

NOBUNAGA Labs Sekirei is an OFC tin-plated re-cable that uses proprietary technology to achieve dynamic, dense mid-low range and excellent separation ability.

■OFC tin-plated wire for deep and rich sound
By using 133 ultra-fine high-purity oxygen-free copper wires of 0.06 mm per core, conductor resistance is suppressed and electrical conductivity is improved. Achieves a natural and dynamic mid-low range. Furthermore, the tin plating process gives the sound a rich resonance and thickness, creating a vivid and extended high range and a deep sound with excellent response. By making the conductor a perfect circle, the flexibility and durability of the conductor itself are dramatically improved. It plays a role in stable signal transmission even when exposed to bending and rapid temperature changes.

■Uses unique technology Symmetric Braid Matrix
The symmetrical braid matrix makes the twisting direction of the positive and negative conductors symmetrical, making the flow of electrical signals as smooth as possible, suppressing the increase in electrical resistance between the conductors, and making it possible to transmit a wide range of sound from low to high frequencies.

■Balanced connection that maximizes the performance of connected devices
Balanced connections use independent amplifiers for each of the player's left and right channels, which suppresses crosstalk to the bare minimum and enables more accurate localization and spatial expression. The 4-core braided configuration is designed to maximize the effectiveness of balanced connections.

■ Eliminate transmission loss to the utmost
In order to equalize the weaving pitch of the cable without performing a soldering process (joint processing) on ​​the branch parts that causes electrical resistance, each cable is woven by hand one by one, resulting in an ideal design that does not change the transmission characteristics. It fully demonstrates the original characteristics of the cable.

■High quality Japanese plug
All contact parts of the 4.4mm 5-pole plug are gold-plated for excellent electrical conductivity. By applying special treatment to the flash plating process, we prevent problems such as peeling of the plating and oxidation erosion, and achieve high quality over the long term. The plug shell uses NOBUNAGA Labs' original matte black design, emphasizing a simple yet luxurious feel.

■High-precision SENNHEISER exclusive MMCX connector
The connector part is 24K gold plated to reduce contact resistance and exhibit high electrical conductivity. In addition, we pursue high-precision processing down to the smallest detail, achieving a high level of precision.
Furthermore, the inside of the shell is molded to minimize trouble when putting on and taking off. The shell part uses NOBUNAGA Labs' original slit design. Black and red lines are printed on the grooves so that they will not fade even after long-term use. (L side is black, R side is red)
*Do not remove the washer from the connector part as it may cause poor contact.

■WBT lead-free silver solder
Adopts WBT lead-free silver solder that brings out high decomposition power. High response and crispness, accurately depicting the outline of the sound, and realistically expressing even the finest sounds.

■Branch parts with a solid feel
The Y branch part and cable slider are treated with black aluminum alumite to emphasize the simple yet luxurious feel. A cable slider is used to ensure secure attachment even when used on the move.

■Proprietary cryo treatment that lasts for a long time
A unique cryo process of -156℃/72 hours is applied to remove distortions in the molecular arrangement, suppress electrical resistance, reduce noise and distortion, and enable clear, three-dimensional spatial expression and information-rich sound with an excellent S/N ratio.
