what happens if you re-shell an UM3X, do you get a ES3X?
does the warranty of the iem get void after you re-shell the iem?
Naturally the warranty for the iem will be void as the casing will have been destroyed. The service provider for the re-shelling will usually provide a period of warranty for re-shelling if the customs don't fit, but I don't think they provide warranty for the drivers.
yup, i wonder if a re-shelled um3x will give you something close to an es3x..mm..
