Oh ha! What chunky Boll Erdinger, high Peinlichkeitsfaktor guaranteed in public transport. This cop is currently priced the same as the Beyerdynamic DT 770 Pro are the same size, but this inconvenient and sonically inferior worlds. The only: the design is a little better, they are not quite as ugly. I own the DT 770 per 80 Ohms and if you know this sound, then the cop is a huge disappointment. Far less differentiated. I bought him because I hoped for a louder, more powerful sound me on mobile devices. None, despite only 16 Ohm no difference in volume to 80 ohms. Added to this was that my copy had a big bulge on the edge of one shell. Well, going back. Who wants to buy the top Beyerdynamic sound for currently about 150 EUR, should DT770 or DT990 buy and have to live with the fact that the things with the ugliest headphones on the market. But this custom one are per anything but brilliant, and if you increase the bass with the sliders, you get a dull mud, where the heights then rather perish. Those looking for something for the road, probably have to resort to other manufacturers. It will be published soon Wohlgenannt a new custom model "street": loud Photos half as big as cop, but then the probably not going to be still sound great again? We'll see ...
