That wasn't very helpful. Spools of metal bracelet wire just. I am looking for clear plastic housing I can slit and place over the iem cable .. like on most ciems
Sorry, not too sure what you mean by that (never really seen or used a ciem before), but maybe the Meelectronics cable guides would work?

If not, you could put memory wire inside of some rubber tubing? Not too sure how thick the upgrade cable is though.
(2.5mm diameter)

or a wider tubing (4mm diameter)

EDIT: nvm, I see what you mean. Problem is, the memory tubing seems to be built into the cable and impossible to put on a completed cable. It looks like the connectors would block you from putting them on. They also seem to be built into the connectors?
You could also using some shrink tubing and shrinking it over some memory wire? You could always cut it off if it doesn't work.
EDIT #2: Yeah, the plastic memory tubing on iem cables seems to be just some regular clear rubber/plastic (not sure which) tubing over some memory wire.
