What Redditors Say
Best praise vs top criticism for Koss KSC75
Top Criticism
+7 pts“After Covid 19 I don't know what Koss did in Europe with distributors but a ton of their catalogue is missing, Koss KSC75 is not even sold directly from Amazon so it went from 19.99 to 30€ with external sellers and the one sold by Amazon also became 30% more expensive. The super interesting new Clear line up is litetally impossible to get here unless it's from them but the shipping cost more than a lot of their headphones :(”

Best praise vs top criticism for Koss Porta Pro
Best Praise
+133 pts“Koss also made the Porta Pro in the 1980’s and clearly didn’t copy this design. Many headphones from that time period looked like this, and let’s all be honest. Koss clearly had a superior design. Hence why it has stood the test of time.”

+457 pts“Yea so after 10 minutes of listening, these sound terrible. Very comfortable tho! The koss drivers were definitely made to be on ear, being that far away made it sound like a phone speaker”
