Yep, exactly. They (any headphone) may sound the best in the world but if its not comfy on your ears and head they're no good for listening more than 2 minutes!
I made a simple mod for my 702s with double sided tape and foam padding. Wont win prizes for looks but who cares, they're indoor headphones

Isnt comparing DT1770 to 1990 like comparing apples to oranges as the 1990 are open or 'semi-open' whatever that is?
Hopefully the 1770s are comfy (dont cook my ears or crush them) and are not too weighty. If so then i'll almost certainly be keeping them.
