Going to try to dispell this "veil" term that has been following this site. So after many flames on this site about what logic Sennheiser engineers used when they made the HD580 series, my assertion has always been that they are wieghted to be concert hall headphones for symphonies. That in a concert hall, bass is what travels and that treble tends to be softer. This adds to body and intonation in strings and percussions. Sure enough, slwiser submitted an interesting link today that talks about the accoustics of an auditorium.

There has been some criticism about why the 580 series has a 10 db dip in the 8khz range....the very reason is concert hall accoustics:
"The graphs show considerable variety from hall to hall in bass and mid-bass response, with the halls that are regarded as desirable for orchestral performances having considerable bass to mid-bass warmth. A less desirable feature of many halls is a slight 250 Hz depression, apparently caused by absorption arising from the seating pattern. In the midrange above 250 Hz up to the 2-4 kHz region, most of the halls are essentially flat. But around 4000 Hz, and sometimes as low as 2000 Hz, virtually every hall begins a rapid roll-off at even quite close-up audience locations. By 8000 Hz, there is typically a 7 to 10 dB dropoff from midrange level. The graphs are not given beyond 8 kHz; but from theoretical considerations, the roll-off at higher frequencies would be expected to be even greater."
Now Sennheiser probably has adjusted and softened the mids in the 650 to give some difference to the 580. To my ears, they actually make greater "symphony" headphones because of their refinement in mids and more extended high treble. So for the anti-veilests predictions about the HD700, I hope you're not right that Sennheiser will "de-veil" the 700
That would mean that the HD650 would be an end of an era for great concert headphones.
