i am asking of curiosity since i heard some sold it again since they could not stand the treble with it.
but i really dont have any issues with my pair after i gave it time to adjust.
in comparison, my hd 660s2 still sounds very good, but lacks in soundstage and it is a darker headphone for sure which is great for some songs but it is not really an allrounder to me
also to me the 109 just seems more alive to me
