I love them, but
It is really hard to get them to connect and fasten back together in a loop.  I don't bother anymore.  Rarely do the move around and fall out.  They are starting to tarnish where they hit my ear.  HOWEVER - I have worn all 4 of them 24/7 for 6 months.  I have not been kind to them.  They are very comfortable.  I wished they lasted longer, but still contemplating buying more.
