Bright and full sound, very detailed, sparkly, airy, tons of treble extenstion... but it gets fatiguing with the stock filters. Blue filter has the best balance but still doesn't scale too well. 300 mesh filter goes hard tho - check modded ranking at bottom.

An interesting sort of Science Project IEM. FatFreq tried to extract as much Sub-bass power and texture while making an airy, detailed planar that isn't fatiguing. They succeeded, and with the Super Stage NOAH modules, this is the most open and wide sounding single Planar I've ever heard. Wish it was cheaper and didn't come with the Ares S II cable.

I struggle with this, perhaps it was insertion depth but that unconventional iem shape should never have been greenlit Average bass, thin midrange, unbearably sibilant treble

Youtube Video Summary

Intuaura Purple brings a polished, pricey package: lush purple shells, a comfy fit, and a cable that looks the part—even if the accessories feel recycled from cheaper siblings. The kicker is the optional DSP dongle (~$65) that re-voices the set; without it, the Purple already sounds clean, punchy, and engaging, with strong clarity and respectable stage. Snap the DSP on and the tuning shifts toward flatter, smoother treble and tidier FR, but soundstage shrinks a notch and the presentation loses some air. It’s a dramatic EQ-by-hardware move—effective, yes, but it turns one IEM into two different takes, which raises the question: which tuning is “the” Purple?

As a pure IEM at $650, Purple holds up: comfortable, easy to enjoy across sources, and free of obvious sibilance when left stock. Compared to lower-priced models that seem to need their DSP to shine, this one doesn’t; the dongle just complicates the decision with a second signature riding shotgun. Verdict: a confident 8/10 for the IEM itself—good build, enjoyable tonality, solid technicals—tempered by the mental tax of the bolt-on DSP path. Buy for the purple “puppy”; don’t let the extra “Honda Civic” in the box talk you into second-guessing what already works.
