Interesting comments, Lug. The DT880 is certainly bright, and I wouldn't generally recommend it with a headphone amp (as opposed to an integrated) unless you have some way to EQ. But once that top is rounded off a little the 880 is an incredible neutral and open phone that just sounds (to these old ears anyway) right, in a way I haven't heard from any other phone, not the HD650, the HE-500 or even the LCD-2 Rev1.
Not sure what you mean by "soft sounding". If I had to pick a phone I wouldn't describe as "soft sounding" it'd be the 880. Unless of course you mean smooth. Also I can't agree that it's light on bass; it sounds just right in that area, with no lack and no exaggeration. Problem here is that not only do we all hear differently and have different equipment, but Beyer offer 3--count them, 3--different 880s, making things really complicated. And not just 3 impedances: the Pro, which I have, has a much higher clamping force and a different lead. Given all that, it's no wonder there are so many conflicting views on this phone.
Still, for me any 880 is better than no 880.
