Howdy!
Are you interested in selling your old Koss HV-1s? Throughout the 70s and 80s these were sold by Radio Shack as "LV-10s". My friend and I both had them back in the day and loved them.
I recently bought a pair and I like them even better after all these years. They beat my Bose, hands down. I'd like to get a pair for my friend's birthday.
Let me know if you want to do business. If the foam is all worn off, that is no problem.
