Pros:awesome sound, last a very long time, very comfortable
Cons:don't really know of any
I bought a pair of these around 1980. They sounded awesome then and they still do. I've had to replace the headband from 23 years of use, and I had to have a wire repaired because the connection simply wore out. The sound is as good as it ever was, very balanced with great punch. I am happy to listen to literally anything on them and I use them extensively now for editing my LPs once captured on my computer.
