Koss Pro/4AA

Cool looks, prepared for broadcasting or chopperuse, not real HiFi.
Still sold by Koss as 4AA version.

Koss K/6a

Fantastic retro-phones. Sound REALLY bad. Sigh.

Koss K/6lcq

Quadraphonic heavy-duty 70s stuff. I never owned a quad-amp, so I don't know if it works...

Koss HV/1a

Those are damn good, some higher frequencies are missing, despite that a fat and groovy sound!
