Make sure you brush thoroughly if you go this route. If that doesn't work, others have suggested, I think Logitech has as well (don't quote me on the Logitech part though), to use a certain chemical to dissolve what's on the contacts (can't think of the name of it right now for some reason :/).
Here's a quick run down of what we feel the problem is. After manufacturing, there is some residue left over from working with the metal contacts. This residue is supposed to dry off and come off as well before the user purchases the product. For some reason, it isn't. So there is a layer of clear residue on the contacts of the IEMs which needs to be brushed and cleaned off.
Thanks so much, tinyman! I'll try this - hopefully that will help! It's incredibly frustrating that this is even a step that I have to go through, especially considering the $400.00 price tag, but if it solves the problem, then I'll take it...
