My GR07's cable is turning green! - Page 2

In any case, what you are looking is not really the wire, but the outer metal sleeve (probably aluminum, for shielding) underneath the outer plastic sleeve. The actual wires are underneath the metal sleeve with its own insulation.

 

While I am aware that silver normally turns black when it oxidizes, whiplash's twag cables have turned green due to a high copper content in the first batch, for whatever reason.  Could just be that this is exactly the same problem - copper oxidizing and having it spread outwards a little so you can see the colour.  Not sure how silver plated copper could turn green, but I've seen others mentioning this happening to silver cables before too...as well as showing pictures of it.  Looks pretty much the same as this.

Guess it could just be that it's the shielding I see.  But aluminum turns white when it oxidizes...so I doubt it'd be any different from silver in this case.

At any rate, I'm simply curious as to the exact cause of this.  I'm all but certain this wasn't here before - it'd be nice if others could take pictures of their cables too for comparison's sake.  And again, I have no problem with this.  Just wondering why it's happening.

Oh, hm, I just noticed a tiny bit of green on the cable on the right side right next to the earpiece.  No green anywhere else yet...but I'll assume it's gonna spread over time.  Guess I'll wait and see what happens here.  My skin doesn't ever touch the cable directly, though, since I use the ear guides.

Actually, it looks like this is an isolated issue from the green marks on the cable before the Y-split...it's happening on the opposite end of the cable.  I'd have expected it to spread from the other end, but there must be something inside the Y-split stopping the corrosion from spreading.  I guess I'll see if only one side of the cable after the Y-split turns green or not, it'll be interesting to see what happens in the end.

No, there's no proof thus far that this is actually corrosion.  Apparently sometimes silver can become green when it comes in contact with PVC, I think it was...or at least, silver with contaminants in it.  Not really sure about this, but I'm pretty sure that's also a form of corrosion, is it not?

Anyway, I sent VSonic an email.  Maybe they can offer a little insight on this.  Maybe it's something that wasn't visible before, but still there, just becoming visible now.  I'm not willing to cut my cable up to find out. :P

Well, I'm not sure if it would affect sound much even if it were all throughout, but it doesn't make any difference to me.  I can hardly complain either, since these were never advertised as having 99.99999% pure silver...I'm pretty sure it's just copper coated with silver or something.
