So my Sonus 7hz cable is cutting sound when I pull it, which means I need new iems anytime soon. But then I remembered I have other iem cables, and so I did a flip, combined ouranos tkzk cable with my sonus 7hz iem, and I have to say it sounds a bit better, but no major changes.
So can the cable make the change?

It’ll only make a difference if the cable is damaged or faulty to begin with.
IMO just get some cables that are comfortable.
