I have HD650's and I'm very happy with them, as I was with the 600's that I had several years ago and sold. But after looking at the frequency response graphs that Tyll provided, I'm mystified as to why the Received Wisdom seems to be that the 650's are more "veiled." The measured frequency responses of these two headphone models are extremely similar, so where is the "veil"?

Revived! Bit late here... gonna have to do some ketchup. Just got a bit of a scare opening up my HD650s to find a HD580 label....

Couldn't seem to find this thread before. If no one is discussing it on head-fi I must surely have a fake! No no... alls normal (whew)... Thanks to Gurra1980! and Tyll!

An additional response from Sennheiser, that I received within 24 hours of asking it, over the time I searched through this forum.... adds something I think...
--------------------
To be more precise: If you order spares for the 3 models, you'll get the following

HD 580 091570 System 300R
HD 600 091570 System 300R
HD 650 092855 System 300R

The systems of the HD 580 and the HD 600 are exactly the same. The difference of sound is only done by the housing itself. Its contour and sound outlet grill, etc.

The system in the HD 650 is a modified version of the HD 580/600. The membrane is the same, the magnet too, but some added materials inside the system differ. The difference of sound is done by the resonator of the system too.

This offers the HD 600 a frequency response of 12.....39000 Hz
and
the HD 650 a frequency response of 10.....39500 Hz.

That seems to be only fine tuning, but with tolerances of the sound at
+/- 3dB it makes it easy to recognize that it is different. The carbon
fibre frame (of the HD6xx series) is not relevant for the sound.

With best regards

Honestly, I've had my 650's for five years now, and I find them to be veiled. I have a few serious audio setups at my house, and the precision/warmth combo just isn't there with the 650's. I will agree, they have great sound staging, but un-veiled they are not.
