Hi friends,

Does anybody want to trade their HD660s with HD600 I have?
It is in good condition, less than 5 months old.
I have an outer box, but not a box insert.

This is a new version, not a kitchen granite top ver.

I realized this is too flat and too neutral for me...
Can't return, so I am looking for someone who has a similar issue and changes what you have with a minimum cost.

Thanks and enjoy your music
