eferesan,
As someone who has the cable with the defect (and is in the process of returning it), my impression is that externally, there will be no difference in the cable. The copper ring will be internal to the bit that contains the plugs that connect to the IEM housing and will function to hold the cable shielding in place (which, in current models, slides off, exposing the copper wire underneath).
That said, the cable is really quite good... if you can get the IEMs to stay in your ears, as this cable is particularly heavy and lacks memory wire / ear guides (doesn't work for me).
