With the exception of the ESP-950, does koss only have 2 types of drivers? The one in the PortaPro and the one in the KSC75. And those may be the same drivers except for the titanium coating on the one. I suspect all the full size cans have one of these 2 drivers in them. Am I wrong for thinking this?
