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
You are asking others about a headphone that you own? Sorry but this makes no sense to me. Would you get rid of it if others said you should. Sorry it just seems a strange question to ask. If it something you like it is something you like and needs no others endorsement. The HD-660S2 is very good in my opinion as well.
I use them almost everyday.
Second comment, so yes I use them but I have two others though they I do prefer. I switch between them depending on mood and laziness
