On these newer multiple driver IEM's (2 bass, 2 mid, 2 treble) How can you test that one armature driver isn't faulty/non-working? It's fairly easy to check on a 2 way IEM. The same as testing a 2 way speaker if a bass driver isn't working it's pretty obvious. But on a speaker with say 2 extra bass drivers unless you go up to them and feel them moving it's much harder to tell. For example if 1 bass, or 1 mid or 1 treble driver on the JH13 Pro is faulty you may never know?
