Material: Silver-plated copper (SPC) or high-purity oxygen-free copper (OFC) mixed with silver.
Construction: Typically braided with 8 cores (sometimes up to 16) to reduce interference and microphonics.
Connectors: Common termination options include 0.78mm 2-pin, MMCX, or QDC for the earphone side, and 3.5mm, 2.5mm, or 4.4mm for the source plug.
Purpose: Often used with IEMs like the KZ ZSN Pro, ZS10 Pro, or Moondrop series to enhance signal transmission.
