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 HiFiMan Sundara
Best Praise
+190 pts“Wife asked me what I wanted for Xmas and I was looking at the closed back sundara as a possible replacement for my HD569 for use on the Sofa. So sent it over but she stated she’d already gotten me my big present. So figured I would try and pick them up in January. But then this arrived. Nice surprise, looking forward to trying them out!”

ViewTop Criticism
+85 pts“I ordered a brand new (supposedly) pair of Sundaras from HiFiMan's Amazon store, and upon opening the box I noticed white dusty stuff on the open back of the headphones, in the finer mesh material. I knew HiFiMan has a reputation for QC issues but I was not expecting *mold*. I contacted customer service about it and sent photos and microscope images. Here's hoping they have a good response. Definitely disappointed but I guess that's the risk you take.”
