Genuine-leather Storage Case
2-Pin Long, 2-Pin Short, MMCX
3.5mm SE + 4.4mm BAL Plugs

Patented Design with Interchangeable Plugs
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.
Patented Design with Interchangeable Pins
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.

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.
