I bought my first pair of these AKGs sometime from 1975 to 1978, and loved them.  Used them for about 15 years until they were damaged in a mishap.  I've had other 'phones since then, most notably the Nakamichi SP-7, but none I liked as much as that old pair from the past.  So when I saw that they were either still - or once again - available (and on sale) I had to get a pair especially since I'm using headphones a lot lately.  I just had to know whether they were as good as I recalled.
