I have the devil headphones Aureol® Massive ordered me at 8:12:12 in hell right and the delivery was made within two business days. Super! To buy I decided after I have searched the internet for days and tested individual headphones in the media market. It first came to the Sony MDR-XB 700 in question. This had the desired bass and was also the highs and midtones well again. Then I found on the Internet by good reviews the devil headphones but due to the technical data would actually be the Sony had been in the first place. But the offer of 8 weeks of testing hearing spoke for ordering directly from hell. For two weeks I have now tried the headphones and the enthusiasm does not diminish. The headphones are bass, midtones and heights again completely exactly. This can be realized exactly by the settings on the audio source, the individual listening preferences. The devil Aureol® Massive offers this a very broad spectrum. To me it is not about the professional judgment. I can hear just liked music and from classical to techno and so on and I think these headphones perfect. I think even the most demanding music and hi-fi lovers will find at these headphones favor. The quality of the product (from the package to the headphones) is very high. Here I particularly like the one-sided and removable wiring. This good quality is also reflected in the outstanding wearing comfort again. Even my big ears fit into the ear pads and even after hours of wear is not the devil headphones annoying. I can only give an absolute buy recommendation and that most directly from hell.
