What kind of pads are you using?
If you're using velours, try the leather pads, they might do what you need.
OK, suffice it to say that I've been bowled-over by the extraordinary clarity and overall near-neutrality of the DT880/600.
I have been listening to them almost every free hour possible, to all the different types of music I have. They are simply brilliant.
Now that I've praised them sufficiently, there is just one area where they fall a bit short, and one where they go a bit too far.
1) They go deep. I played a series of tones and they have great bass extension! That said, they could, to my ears, emphasize the bass just a bit more. Things are just a little thin down there.
2) Highs, ah... we love 'em. Love them crisp and present, but these are still just on the edge of being almost too bright.
These beauties have burned in nicely. I probably have 150-200 or so hours on them; everything from pink-noise to classical to punk. They have 'mellowed' quite a bit since I got them, but seem to have reached a plateau. Not much has changed lately.
While they are clearly the best headphones I’ve worn: Certainly the most comfortable and detailed. Where do I go to get a little less in the 6-10khz range and a bit of a bump in the 25-400hz range? I really could live with these… for a long time. But if I wanted to just go a little farther, maybe just one more…
What is going to maintain the overall sound signature, but change those two minor ‘characteristics’ for the better? I have no issue with closed cans, and they might actually yield the better result for me.
DT770/600 or DT990/600?
(Having owned the HD600, and loved them for many reasons. Warmth, richness… they just didn’t have the clarity or brilliance in the highs.)
I'm asking here because you are all DT880/600 experts and appreciators, but if this has already been well-addressed, let me know.
