Why? The D5000 is clearly stronger in both the upper midrange and treble regions relative to the 650. The 650's lack of presence in these spots is what has given it a reputation for darkness, not its strong bass response. Bass 'bloat' is far more complicated than FR graphs can indicate, however in FR terms you are talking an excess in the 100-250hz range, not the 0-100hz range where the two headphone's response curves diverge. Therefore, in terms of 'darkness', the 5000's response curve suggests a somewhat livelier, more 'forward' presentation with similar bass characteristics.
I'd venture that the rising bass response of the 5000 ought to be a little more accurate at the ear than the hump of the 650. After all, the lower in frequency, the greater output is required of a pair of headphones to match the real life experience of such frequencies, as the bone conducted component becomes more and more important relative to the diminishing air conducted component of the sound in terms of our perception.
Of course, that's all pretty meaningless next to a good set of ears, but it does tell me that, given my ears, they are worth an audition.
