PW Audio Ground Pin Adapter Box for Sony NW-WM1AM2 / NW-WM1ZM2

Unlock the full potential of your Sony NW-WM1AM2 or NW-WM1ZM2 Digital Audio Player. Handcrafted by HK master manufacturer PW Audio, this precision-engineered 4.4mm ground pin adapter connects the 3.5mm ground line to your 4.4mm balanced output, creating a continuous shielding loop that dramatically lowers background noise and elevates audio clarity.


Key Audio Features & Benefits

  • Advanced Grounding & Shielding: Connects to the 3.5mm ground terminal to route ground shielding directly into 4.4mm balanced cables, significantly mitigating signal interference and electromagnetic noise.
  • Premium Internal Wiring: Built with 28AWG high-purity compressed copper inner wire for optimized electrical conductivity and low-distortion signal transfer.
  • Pentaconn 4.4mm PCB Socket: Equipped with premium Pentaconn 4.4mm female sockets for maximal contact area, secure connections, and long-term mechanical durability.
  • Precision CNC Alignment: Measured and manufactured to exact specs so the male plugs line up smoothly into the Walkman ports with zero physical strain on the player chassis.

Available Internal Core Editions

Choose the internal wire core configuration that best matches your sound preferences:

  • Standard / 1960s Version: Internal wiring utilizes legendary PW Audio 1960s flagship wire cores for signature warmth and resolving detail.
  • First TimeS Version: Hand-soldered with FirstTimeS internal cores and paired with PW Audio's proprietary premium Rhodium-plated 4.4mm plug.
  • Orpheus Edition (Gold Limited): Soldered with flagship Orpheus wire cores and built using Pentaconn OFC (Oxygen-Free Copper) 4.4mm connectors for ultimate soundstage and signal purity.
