It's well known that for monitoring, mixing and mastering it is better to use Monitor speakers, but if there's a need to use headphones in that order, this studio headphones might be a good option. First of all, it gives a very decent sound, if you're using it for what it is made for. It has a smooth base and middle frequencies range, though I am not sure about the high frequencies. For one it might not seem clear enough, but if you have a good musical hearing, then you'll probably value the fact that it actually provides the great clear sound of every detail on each frequency level. And what might seem unclear for the layman on the higher range, is actually a lack of enhancement in it, due to the product's mission as a studio headphones, not high-fi. In comparison to some other Studio headphones, it has less powerful/ loud sound, which is a plus, when you are mixing or monitoring, because human ears can get tired easily of the too loud volume. So that is actually a plus to me. The quality of the fabrication and materials is decent as well, the only point that I would like to change is non-detachable wire, unlike some studio headphones which have that convenient option, providing durability. So, yeah! Pretty happy with that product anyway.
