Nice but not good

As much as I would have these very stylish headphones behalten.Genauso Headphones need to look - the current bestseller a la beats etc. are much too monstrous.
Pro:
* Appearance and detailed sound.
* Great accessory and perfect Trageset.
* Elegant packing material that is strongly reminiscent of Apple.
* Good microphone and call without any problems

Cons: A Rezensient wrote about the fact that you have to first "Listen-" headphones for the right sound for a few hours. That's what I did because he loved them.
The maximum volume is even for my taste insufficient, and yet I do not hear very loud.
For Sound: This is a highly differentiated and you can really speak of a stage, all very harmonious. BUT: Weak bass and very very stressed highs, for me overkill though I generally like listening height emphasized.

As a mobile companion of Koss is serving - as studio headphones he is good at mixing etc. not good because it is too low and the treble and bass can not be considered good.
