The cable fitted to your ACS monitors is of the highest quality. Manufactured to our own specification, each cable contains 80 strands of 100% oxygen free copper with each strand plated in pure silver. Aramid fibres (Kevlar) are woven into the twists to provide exceptional pulling strength and breaking strain. The sheathing on the cable is treated to dismiss harmful UV rays and will not discolour or oxidise like many other inferior cables. The design of the cable provides the best connectivity between your audio source and the earphones. When the cable is fitted at the factory it has optimum contact to the cable socket, therefore we strongly recommend that you don’t disconnect the cable unless it requires replacing.
