I would doubt damage that isn't defect related would be covered by warranty. Aside from Monster and their new Monster Turbine Pro series of IEM's I know of no other manufacturer that covers accidental damage as part of their warranty. On a positive note I have owned the ES7 and they open up very easily so can be repaired. If your not a DIY search the forum and see if you can find someone who can help you out. Personally I would be getting a soldering iron and googling how to solder the wires and trying it myself before going to an outside source.
If the cable is completely ruined also look at the DIY sections as they can help you pick out a cable as a replacement. Just avoid buying the really expensive cables as the headphone is not high end enough to warrant their cost.
