If I already have the 58X and HD6XX is it even worth it to check out the 660S?
For me that i have 58x 6xx 600 650 and 660s , yeah it worth it.
But i am from those that look for small details. If u expect night a day difference nope there is not.
58X are to my ears the weakest of them all.

Yes that is what I have heard. But how much "better" is the 660S over the 58X?
From 58x a lot if u really listen and give attention. I dont get why people say 58x are close or the same like 660s maybe the sound signature thats close make them think that.
From 600 650 i wouldnt say much better but in some parts better and others not.

A little bit off topic but, what do you think about 6XX and 650 . I never heard 650, briefly heard 600 some time ago, but from memory and looking on frequency response charts it seems that 6XX may actually be closer to 600 rather than 650 or are 6XX and 650 actually the same or is this the case of 580x and 660s where the cheaper 6XX is a bit worse. Is worth having the 650 too then?

For my side, Hd58X is similar to HD660s, is a more proper comment. The release date of them is HD 580X after HD660s, and 660s after 700
From my side 58x are not similar to HD660s .
660s share the same blue driver like HD700 but the sound signature is way different but from technical point of view speed imaging sepperattion tightenes power to drive them there are similarities.
58X driver and pcb compare to 660s.is way different its easy to see it , the sound signature is close and thats it everything else is different and way better on 660s , also even if they write 150ohms i am sure 660s are harder to drive compare to 58x.

This is my opinion and what i have 6xx 58x 600 Ireland and 660s 650 Romania So i dont know if there is some kind of difference on factory.
To me 58x are not in the same League that all 6xx 650 600 660s are . They are great like 560s but thats it.
6XX are not close to 600 i can surely hear the mid bass and the smothness character vs the 600 , 6XX vs 650 i can hear the same character but some times 6XX are more trebble happy on some songs not by a lot but it sounds like 650 is smooth on everything and 6xx is like something happens on some instruments that sound more can i say bright ? I dont know if its the pads because i have a lot of hours on the old ireland ones and honestly i am not changing them to benchmark but they are surely softer pads and i guess they affect sound .
So no 6xx are closer to 650 for me and clearly.i can hear the mid.bass warm character and.smoothness to them.
So no its not the case ... 650 6xx 600 660s are all on the same level to me with the 660s beeing better on something like speed imaging sepperattion resolution , 560s and 58x are very good but clearly a level down.

Both my 6XX and 660s are made in Romania. I also like 660s better in almost every way. The sub-bass is better on 6XX, mid bass is around the same and mid instruments have about the same fullness. But everything else is better on 660s. Even if people say 660s is expensive I actually think it's worth the price difference from 6XX for someone who is interesting in small details because the differences are not big of course, but I like a lot those small differences on 660s.

Drop sells HD6XX romania versions ? Oh i didnt know about that , i thought they have only the Ireland versions and not the Facelift . So your HD6XX have the FL design with catted corners and the marks for the left inside ? If tis easy can u share a photo ? i have never seen Romania HD6XX

I think it's the same design?! Just in the box it said made in Romania and the same it is specified on massdrop site if you look there.

So they say Romania but they are the old stock ones pre facelift?
The new Sennheiser HD600 650 660s look different for sure.
An easy way to spot are these 3 dots at left side .... New ones from 2019 have them inside.
I guess Sennheiser gives stock old ones to Drop thar make sense.

Very close in tuning with a mid treble dip for the MG and of course greater bass extension and a peak at higher treble.
Of course frequency response can't tell the whole story.
U are absolutely correct what i find out is that a frequency response is the half of the story. I have heard headphones with W shape that i like and flat that i didn't , even that i prefer flat warm response.
