Purchased new and stored in a dehumidified storage unit after a single use. NOBUNAGA Labs Advance Kirifuri (霧降) Achieves a sense of dynamism with rich, dense mid-low frequencies and excellent separation. Features proprietary OFC tin-plated cable. OFC tin-plated wire for rich, full sound. By using 133 ultra-fine high-purity oxygen-free copper strands, each 0.06mm in diameter, conductor resistance is reduced, and electrical conductivity is improved. This results in natural and dynamic mid-low frequencies. Furthermore, the tin plating provides a rich resonance and depth to the sound, achieving vivid, extended high frequencies and a dense sound with a heavy, responsive feel. Rounding the conductors dramatically improves the flexibility and durability of the conductors themselves. It maintains stable signal transmission even when exposed to bending or sudden temperature changes.
