Bought only on rare occasions my listeners. For every day I mainly the Koss Porta Pro in use of a different class than the HZZ, but a small Bügelköpfhörer is. First, notice that the listeners have very aggressive highs. One has to adjust otherwise it will unangehehm. I mean, I like it eigenlich height emphasizes what. The centers should be something highly regulated otherwise z.Bsp. Guitar Acoustic is too little audible. The bass is more than ok. For comfort I can say anything yet see that he has flat cable, which is good against cable wigs. One must say, unfortunately, that the listener sound different in each volume. All in all it describes him well as a very unbalanced. But for my needs I get back an acceptable sound, especially since I intend to use it preferably for metal music. If you can live with these errors and its sound balance at a certain volume which can access at this price. As a standard headphone is probably not useful and even not at all if you're a friend of the quiet sounds. Oh yes. It is extremely loud.
