[Boatanchors] Do Headphones Age-Away?

[Ron VE8RT]

  As no one has replied yet, I think that this may be helpful:

  If the earpiece is made using rochelle salts then yes they do
deteriorate (more rapidly in a humid environment) over time.

  It is also a problem with antique microphones.

  I would not be able to help with the question as to whether anything
can be done about it.
