Should Sennheiser do a 660s closed back?

along the lines of say a Beyer DT1770/177x?

I mean, that’s kinda the ndh20 bit with a different tuning. It would be cool but hearing the 820 I’m pretty meh on the idea

But that’s a “Neumann’s” studio take on a Senn (does the ndh20 use a 660s driver?) not a Senn tuned closed back/ otg headphone.

I guess that’s true, the closest they have might be the new version HD1 but they don’t really have a closed hd6xx series

I don’t know what driver the ndh20 uses
