Hmm, mine broke a long time ago.  The plug and big box thingy are separate, 
connected by a bit of (slightly flexible) rubber.  Mine broke at the rubber 
joint between the two.  The big box is free and I can slide it along the cord 
all I want, so it appears to serve no purpose.  I just opened it and it 
contains two pieces of metal (not magnets) which encase the cable when
closed.  Does anyone know what it does?  Shielding?
