Watch Akros on youtube for the deepest comparisons and reviews (with graphs) of all current IEMs. I am a full on addict and have most of them in the $80-$500 range and then I have the Monarch 2s. If I can help advise on some that might match your preference hit me up. Right now my favorite IEMs in that range are the Letshuoer Galileo and the Tri Starsea.

I like to collect down votes for crapping on any EQ use but this is the one use case where it is totally appropriate and justified.
