ddHiFi BC120S 4.4mm Balanced Earphone Upgrade Cable

(Standard Cable for ddHiFi Surface IEMs) | 0.78mm 2-Pin

Description

Introducing the ddHiFi BC120S, a robust and high-quality upgrade cable originally designed as the standard companion for the ddHiFi Surface multi-driver earphones. Featuring a substantial 1.8mm single-strand wire diameter and conductor shielding technology inspired by the premium Nyx series, the BC120S is built for durability and performance. Its transparent PVC jacket showcases the thick silver plating, while the unique winding structure ensures a surprisingly soft touch despite its strong appearance. Finished with custom CNC-machined aluminum hardware and a standard 4.4mm balanced plug, this cable offers a significant upgrade in both build and potentially sound quality for compatible earphones.

Features

  • Robust Construction: Features a thick 1.8mm single-strand wire diameter for enhanced durability and a substantial feel.
  • Premium Conductor Material: Utilizes High Purity Oxygen-Free Copper (OFC) cores generously plated with a 3u thick silver layer for optimal signal transmission.
  • Advanced Shielding: Incorporates conductor shielding technology inspired by ddHiFi's high-end Nyx series cables to minimize interference.
  • Litz Structure: Both core (0.10mm x 30 strands) and shielding (0.05mm x 116 strands) conductors use a Litz structure to reduce skin and proximity effects.
  • Strong Look, Soft Feel: Transparent PVC outer skin reveals the solid build, yet the unique winding provides remarkable flexibility and softness.
  • Custom CNC Metal Components: All hardware (plug housing, Y-splitter, chin slider) is precision-machined from aerospace-grade AL6063 aluminum alloy for a refined and durable finish.
  • 4.4mm Balanced Termination: Comes standard with a durable, injection-molded 4.4mm balanced plug for use with compatible audio sources.
  • Secure 0.78mm 2-Pin Connectors: Features reliable 0.78mm 2-pin connectors (3.5mm long type) with a grooved and stepped design for a secure fit with many IEMs.
  • Surface Standard Cable: The official cable provided with the ddHiFi Surface earphones, ensuring perfect synergy and also available as a standalone upgrade.
