What's sad about that little system is not so much that it exists, since somebody can make use of it, but that it carries the once-proud Koss name. How are the mighty fallen! John Koss started out in the 1950s making all sorts of audio products and breaking new ground in research, peaking in the 1980s with an electrostatic headphone. By then, Koss was involved in studio montoring/classical recording and worn conspicuously on the ear by all sorts of people with pretensions to good sound. Now? Well, L.J.'s picture says it all.
