Basically, I was with the Kofhörern since I bought it months ago about 6 very satisfied. My only problem with the Kofhörer was unfortunately quite strong transmits sounds as you move through the cable itself. The main reason that I forgive only 2 points is that the headset is in normal use approximately 1 month before the first break times. However, it was at one point (on the side where you can adjust the height) at which it lies easily be solved by an adhesive tape. Yesterday he is but broke down for the 2nd time and just above the ear. Unfortunately, it is almost impossible to stick to this point it back.
Now I'll probably buy a Sennheiser 201HD hopefully keeps the what it promises.
