When I first had the headphones on, a wow factor stood first one with me. I had previously perceived music has never been so clear and present. For me the sound of the headphones is very pleasant ,, '', nothing affects me overridden or the like. All frequencies are depicted very natural and the bass fits me very well into the overall picture. It is neither too strong nor too weak, and perfect for my ears. Of course one must not attack à la Bass Beats expect, but that's my feeling also complete nonsense, since other frequencies only suffer. So by me clearly for the Sound 5 star.
Processing I find also very well done. The headset has a very pleasant contact pressure so that it permanently hear even after 3 hours with me was not unpleasant. Everything budge, it creaks or wobbles nothing and the headphone looks in Natura simply just awesome. Also it 5 stars.
Finally, I would like to mention the included accessories. In addition to the headphones can be found in the packaging a little guide, but I have not looked at me, a very nice leather bag to safely store the headphones and three replaceable cables. A 1.2 meter long, straight cable, another 1.2 meters long, straight cable with microphone for phone and a 3 meter long, straight cable. Unlike the ATH-m50x, there is however no locking mechanism to secure the cable, but this is inserted only as normal. Also for the accessories I can not forgive other than 5 star.
So, full marks from me for this product and I hope that I can help in some decision, even though I have no real experience in this field. Furthermore, in the near future will upload a few pictures of the packaging and the headphones.
