Why is the synergy between cables and IEMs important to some people?
I have almost always heard that cables make no difference—that they produce no changes in an IEM's audio reproduction, that they are an unnecessary expense, and that they simply aren't worth it. However, there are others who believe that swapping cables actually improves an IEM's audio performance, that it allows for aesthetic customization to suit personal taste, and that it unlocks new performance characteristics in the IEM. What is certainly true, however, is that utilizing a 4.4mm connector offers tangible benefits in terms of audio performance; the cable's amperage is significant, and the composition of the conductor is fundamental to enhancing an IEM's inherent qualities. Ultimately, the result comes down to whatever you want your ears to hear.
