Vintage Yamaha YH-100 Orthodynamic Headphones Boxed Excellent Condition

  

They look brand new to me. I took them out of the box and listen to them for a few hours to make sure they were working perfectly which they are. For anyone who hasn't bought vintage electronics before, Styrofoam has a tendency to degrade and stick to rubber over decades.

So the cord did have have some Styrofoam on it. I have removed most of it.
