The retro design is superb, the optimum listening, the quality of materials properly scandalous. This is the third time that the cable snaps my fingers, not from the sound of a listener. For the first I thought it was an accident, the second I had a bad fall with the third just dropped me in a daily commute, without warning, leaving only doubt. Special mention for the last copy that dies just two months and a half (2 ½ months !!) after you buy, you can not restart the warranty is still studied well ...
Appraisal: 120 spent 3 identical products which have given me a year and a half. A shame. Koss is resting on his laurels: "Guys, it's amazing, the same design we kept since the 80s!", Yes the design, the materials are themselves well today, good low-end pastique which explains the low price of the product.
Too bad because listening was very good, that's why I got hooked. Do not make the same mistake.
