Radio Shack has a pair on sell for $69. They say Optimus but they look exactly like the A130 and even have the word Koss on the cord. Anyway, are they worth that much? Anybody ever tried these? I would have listened to them but they had a 1/4" plug and Rat Shack had nothing that was working to plug them into. I may take an adapter and go back but the source is going to be really really bad, FM radio off one of those mini-systems most likely although I could probably take a cd and use that instead.
