I think the closest analog would be the 64 Audio U6t in terms of a similarly priced product that I actually have any fondness for + that goes for something somewhat similar. It has similar build but a less appealing look and comfort (for me), and is kind of the same theme as every other product I compared: Lumen has more control in the bass, more accuracy in the mids, and much more smoothness in the treble. Don’t really perceive any reason to get U6t for neutral playback if Lumen is also an option unless the user has very narrow ear canals that need a narrow nozzle for fit. Lumen also has a nicer cable.
I figured another 3 paragraphs (or more, if I brought in more comparisons) where I say essentially the same thing about all of them wasn’t especially helpful considering the piece is already quite long 
To be extra super clear, the reason there aren’t more expensive IEMs included for comparison is because I like them less than Pure, Volume S, Mega5EST, and Daybreak.
