Double shielded coaxial structure

In order to get better tensile resistance for over-ear headphones upgrade cable,
the normal practice is to wrap the multi-strand braiding cable with netting to avoid looseness. Instead, the line structure of the BC150B is designed to make the two sets of signal lines into a coaxial structure, and add a layer of shielding to the outermost layer
so as to form a double-shielded coaxial structure with three layers of conductors and three layers of insulation. Such a structure has excellent tensile performance, and creates a cleaner background sound for signal transmission.

It's far more than pure silver

The main core conductor is made of two kinds of pure silver with different diameters, and mixed with silver-plated OCC and Furukawa silver-copper alloy. The cross-sectional area of the conductor is up to 22.8AWG, which can meet the needs of high-power transmission and also guarantee the transmission efficiency for different signals. It also contributes to the sound quality, which makes the timbre expression of different instruments more accurate, and the sense of sound positioning clearer.
