Are you guys actually using Youtube to test your cans or are you just linking examples? The sound coming from Youtube is compressed garbage. Sometimes it's not even the correct pitch.
For me its just a mistake from Sonarworks , their 660S graph doesnt make sense just look at the low end graph , everyone with older or newer 660s can hear less mid-high bass compared to 650 . I have send them a message way back and I got no response.
Also this Sonarworks true fi that I used on 650 , 660s ,Bose ae2 changed the sound signature in a way that I didnt like it , doesnt feel smooth for me . I guess Sennheiser and Others with more XP know how to tune the Headphones to be more appealing on real life hearing , some say that dips on sound signature are there for a reason. I can understand that its all about taste , personally I didnt like it and unistall it . Most of my headphones are neutral signature so …
Ok, what does this group-delay chart comparing the 650 to the 660s indicate?

WHAT are they trying to accomplish in the 660s with those major opposing peaks, and that secondary GD peak in the left ear? Is that an attempt to remove the so-called "veil", or what?
Maybe concentrating on FR is only *part* of the equation..
I just got a pair of these. They are the Ireland version with the 'see through' badge. I thought I read where the ear pads were thicker on the 660's but they are no different then the new ear pads I just got for my 600's. In fact, I was just looking at the Sennheiser store in Germany and they only sell one pad for the HD 600, HD 650, HD 660 S, (etc) headphones.

To my knowledge pads have never really changed. The second pair I received had the older model number but the box stated it was built in Romania. It also didn't have the Made in Ireland stamped on the side. But it kept the older style headband with the 3 dot markings on the side. Badge was not see through either but in person it didn't bother me as much as I thought it would. In terms of sound they sound exactly like the original 660S when I compared it to my older set.
See @Asspirin post above for the correct info on the pads.
From what I can gather and from my direct experience of four HD660S models the timeline was as follows:-
1./ Original production model. Made in Ireland and had 'Made in Ireland' stamped on inside of headband. Original box with Made in Ireland printed on it. See through Sennheiser 'S' badge.
2./ Same as the above but with solid Sennheiser 'S' badge.
3./ Original model, but production moved to Romania. No 'Made in Ireland' stamp on headband (obviously). Original box but with adhesive sticker saying 'Made in Romania' over the printed 'Made in Ireland' text. Solid 'S' badge.
4./ New model (updated stying) made in Romania. No country of manufacture stamp on headband. New style box (outer sleeve - the actual box is the same) with 'Made in Romania' printed. Solid 'S' badge.
If anyone has any corrections or additions, please inform!
I've been reading (here on this thread) that after the first three months or so Sennheiser changed the sound of the 660's. If true, you could add one more to your list.
There has been a slight change to the earpad. From what I can gather the earpads are slightly thicker and have a slightly beveled inside circumference. In this Head-Fi post a Sennheiser representative said is was done to make them feel a little more "roomy and pleasant." I went back and forth between my HD 650 and the HD 660 S and felt indeed there might be a small improvement in comfort, but it is subtle.
