How I hear the UM3X. This is running Shure Olive tips which I try to use for most small nozzle IEMs. The Shure tips don't color the sound. I use a pink noise track and software EQing that is for all intensive purposes infinite in adjustment. The earphone is powered through a Meier 2Move connected to my laptop using the built in DAC but patched through a virtual line plus software that lets me tie in EQing. I've EQed most everything I've owned and have used pink noise as my tool of choice for EQing for earphones as well as custom car audio setups currently and through previous years. This is of course my own perception of "flat" as my ears hear it. Again, this is using the Shure Olive tips. If you ran the stock Comply tips, more midrange and high end will be lost. I did like the long Comply tip more than the short one. Trebles were more sparkly, and the long tip didn't have an odd midbass hump that the short one gave. This is why I like the Olive tips, zero coloration, comfy, and super durable.
