CSDs

Do you hate them because they lack warmth?  I always imagined these having cold tonality and basslight based on impressions.  FR looks like this is the case.  Very clean though!

Pretty clean measurements though I did not like them very much either. Funny how people like to call this 'neutral'.

They are midrangy / hollow, in a weird medical device (check your hearing) kind of way. There's a slight hardness to the quality of the treble. No much perceived air, although the measurements do not seem to indicate this.

I hope my use of audiophile terms is not too pretentious or ominous (as in Orwell / 1984)

One place where the measurements may differ from how you hear them to be is in the seal. I get a much better sound out of them when sweat seals the cans giving a vacuumlike feeling. without that seal, they sound hollow without being modded a little to grip tighter on your head. Can you try putting the mics in your ears while measuring to see the difference vs the dummy head?

I am not a super big fan of the dt48 but when getting the proper seal, I wouldn't put them in the craplist 

I think Milos's gallon drum of lube ought to do the trick.
