Uses 19 OFC wires of 0.08 mm per core. It suppresses transmission loss and demonstrates the original ability of the cable. The OFC wire, which has excellent electrical conductivity, achieves a very well-balanced, natural sound from low to high frequencies. In addition, 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.
