Cable Build & Design

The cable is made of silver plated OCC copper and OCC copper. It has a 6 core braided design. The Booster Blue I will be reviewing has 2 pins 0.78mm connectors and 2.5mm balanced jack. The cable can be customized in many ways subject to the availability of the component. Each conductor has a PVC jacket insulation. Each connector has a silver housing with blue and red stripe on the left and right side respectively. There is grip on the connectors. There is a memory wire area section in which the cable is enclosed in a translucent heat shrink tube. There is a metal inside to form the shape.The chin slider is translucent clear and the y-splitter has a grey housing with the brand logo printed on it. Lastly, the jack is 2.5mm balanced straight gold plated. It has a grey housing and there is strain relief.
