Key Features：

1. Furukawa C2200 Brass Alloy Wire Core – Highest Copper Proportion – The copper proportion of C2200 brass wire core is the highest of Furukawa C series. Made by four kinds of materials – copper, zinc, lead, and iron – in precise proportion to achieve the most outstanding performance in the brass wire series.

2. 18AWG – 4-Core Litz Braid – 240 Total Strands – 60 strands for each core – 240 strands in total. Adopted two kinds of alloy wires with different diameters designed and paired in scientific proportion. Larger wire diameter and lower impedance – fully realizes the excellent performance of C2200.

3. Imported Dupont PVC Cable Coating – High-quality imported Dupont PVC outer jacket provides excellent durability and flexibility. Protects internal conductors while resisting tangling and wear – built for reliable daily use.

4. Sound Feature – Solid Imaging & Powerful Performance – Black Blade is a black Japanese sword with the feature of being solid and tough – the same feature of our Black Blade upgrade cable. Solid imaging, powerful performance, and comprehensive improvement for all three frequencies.
