Query: Waste of money just horrible.

Well where do I start they don't fit well I am constantly adjusting them to keep them on my head, since KOSS has a lifetime warranty I had to replace them twice that is three headphones within a year. I lost sound in the right one on the first purchase then the left one, then the plug went.Not sure if they just gave me a refurbished headphone when I replace it the 2nd and 3rd time. Save yourself the headache try another headphone. I don't know what is going on with the quality of products but I have had headphones for my other players in the past that worked great. I guess I will keep looking.
