Nyx Gold – BC130G
Multi-Functional Earphone Upgrade Cable
Patented Design with Interchangeable Plugs & Pins
As a fully realized member of the Nyx series, the BC130G supports ddHiFi Nyx Pin series on both plug and connector terminals for simple plug-and-play replacement. It comes standard with 3.5mm and 4.4mm plugs, as well as 0.78 2-Pin and MMCX connectors.
The interchangeable plugs adopt the Mini‑XLR 4‑pin standard. Compared with ordinary plug connectors, this design features a longer insertion depth for more stable and reliable connection. The innovative combination of Mini‑XLR 4‑pin connectors and audio plugs is protected by ddHiFi utility patent.*¹
*1 Patent No.: ZL202421716734.5 | Utility Patent Name: A Structure Adopting Mini XLR Plug for Audio Plug Conversion
The interchangeable pins feature an innovative dual-structure design, enabling mutual replacement between parallel and axial structures. This breakthrough connection structure achieves compatibility with three mainstream earphone connector types: 0.78 2-Pin, MMCX, and Pentaconn Ear. This unique structural solution is also covered by ddHiFi utility patent.*²

Innovative Air Core Conductor Geometry
The internal cable structure adopts tubular Teflon FET isolation, which separates signal conductors to form a high-purity air insulation system. The outer conductors utilize two distinct optimized geometries: a cross-braided structure for the positive signal and a unidirectional spiral twisted structure for the negative signal. This innovative structural pairing endows Nyx Gold with an open, transparent, and spacious sound performance.
Genuine-Leather Storage Case with Aluminum-Alloy Frame
The package comes with a C90B orange litchi-grain storage case as standard. Built with an aluminum-alloy tube support frame and wrapped in premium top-grain leather, it features exquisite litchi texture and a soft, full hand feel. With precise craftsmanship, the lid fits the case body perfectly without gaps. Reserved bottom vent holes release internal air pressure to avoid jamming during opening and closing, delivering ultra-smooth operation.
