Doug,

Remove the screw and separate the ear piece. Look at the hinge. With
needle nose pliers squeeze the hinge a little tighter. Test and tighten
until you are happy. Reattach the earpiece using thread cement or nail
polish on the screw.

One trick you can use towards this end is to insert a shim into the
hinge so that when you compress it with the needle-nosed pliers you
don't compress it too much. Those little parts don't have a lot of
feedback, and it's hard to stop at 1/64" without going full tilt to 1/32".
