Reference Cable
The letter R in the name of CABLE-R stands for REFERENCE, that is, it is designed on the basis of the original sound, great significantly improving the acoustic performance of earphones, delivering a more condensed and transparent sound, and maintaining its own balance and transparency.

The Power of Structure
Each strand of CABLE-R is composed of single crystal copper and silver-plated core of single crystal copper in a specific proportion. In this structure, the single crystal copper cable is used as the inner axis of the coaxial structure, the single crystal copper silver-plated cable is used as the outer axis core, and the silver foil with shielding is woven across the main strand. The earphones' sound performance can be optimized while maintaining the original sound by adjusting the twist density and spacing and the cable capacitance ratio.

Low Oxidation Welding
Use Nitrogen welding equipment to weld with AUDIONOTE solder. And wrap the the solder joints with Nitrogen during operating, so as to eliminate Oxygen in the welding process, to take away the excess heat while reducing Oxidation, to ensure the solder joints between cable and connectors firmer, and avoid degradation of conductivity.
