I used to be a big fan of K400 (see my former name) but then moved to TH900, which of course is a very different price area. So whoever wants to have a classic fun headphone, let me know. I did the balanced mod myself using a Sennheiser balanced 2.5mm plug. I used an original AKG K701 cable as replacement.
Maybe not the most pretty, but of course in fully working condition. Headbands where shortened to give them back some tension.
