go to any electronics store and you 'll hear they say , `` do not buy Koss '' . while some review site that one person think be `` the authority '' say it be quality , review site do not use the product beyond a initial test . I have own mine for three month , and originally , I think I get quite a steal . now the thing be dead , nothing more than awkward paperweight .  whatever you do , do yourself a favor , save up a extra month or two and buy a quality sound system . do some research even beyond this site and you will find that Koss be a huge waste of you money .
