Processing: Unfortunately Made in China, as opposed to most other products from Beyerdynamic. The quality I would as ok - good call, at the price of my expectation is, however, a little higher. All parts are custom-fit and have been assembled properly. Nevertheless, a high-quality and solid impression is not conveyed.
Comfort: unfortunately only satisfactory. In the beginning they are indeed well on the ears, and the ear pads feel very good, but to me is the pressure too great - especially since I'm wearing glasses. After no more than half an hour it will be more unpleasant.
Sound: And here the KH its strengths sovereign. My reference is the Sennheiser HD 600, AKG 701 and Beyerdynamic DT 880, and since the DTX 501P does not bad as a mobile solution. The resolution is sufficiently clear and transparent, mids and highs are consistent, and the bass I emfinde be very precise with surprising depth. For my taste, it could, however, be less bass a tick. He is in no way intrusive. The stage I would describe as rather small, but is certainly the enclosed design owed.
Classical music is not his forte, but Jazz, Electronic, Pop & Rock, and especially radio plays, he copes very well.
Clear - one may wonder at the price range is not expected, but it sounds better than most competitors, some of which cost considerably more for me.
I like the sound of my mobile players so well that I take the compromise on comfort and processing in purchasing. From me a strong buy recommendation!
