Nice write-up.
How do the JH13s compare to other CIEMs in your collection, like the 335DW for instance?

awesome CIEMs are awesome!

Well as I pointed out in the forums, the JH13 is like a wide stage, flat but you can hear the distinctness of the instruments, while the 335DW is a 3D globe around your head. Also there is a bit of treble roll-off with the 335DWs. I'm working on burning in my Hidition NT-6 Pro to compare as well

A Laz A.D fan! Good taste with the reference listening.
