Thanks! I'm not sure about the specific IEMs (impressive and exhaustive list in that link!), but these are two of the few I was able to try first hand, and due to being outside the US/EU, availability (and option to return/replace/resell) is a problem. Everything is so subjective in this field that at the end (beside EE fundamentals regarding noise floor etc.) it's a question of "am I enjoying my music?"
This is a great thread, thanks for spending the time to answer everybody. I currently have the Fulla2, and I'm considering getting the SE535 or the SE846. Do you think it would be worth it to invest in some better combo/stack?
