So I'm away from Koss and have therefore brought me this Ultrasone. The sound is very good for the price, but I miss more bass. The Koss has properly oomph, and whom I like, get little money for a great headphone. If then however constantly the cable slack makes, you have at the end none of it.
Disadvantage of the Ultrasone except the lack of bass strength: He sits unfortunately somewhat loosely on the head, because the strap has almost no suspense, and thus is probably not as suitable for women. Too Bad. But I keep it anyway. Maybe you can replace the strap against another, which is slightly less or having more power.
Overall, I am satisfied. For the price there are certainly much worse ultralight headphones.
