I gave it a listen to still my curiosity. First the included tips have an odd fit that allows for
a lot of vertical movement on the nozzles. Second the white tips are so delicate, one piece had a tear out of the box!
Sound impressions with white medium tips, switches 1 & 2 on:
The presentation is mid forward. Fairly clean tuning. Slight low end mud, and slight mid harshness, on occasion. Free from objectionable treble sharpness.
Voices are nicely present, articulate and intelligible, but not very intimate. Drums and percussion have nice snap, but sound small. Only moderately immersive. Distinctly favors hard rock due to the mid forward sound signature. Non-distinct staging.
Reminiscent of 7Hz Salnotes Zero, fixes the hot treble and lean bass, but with it's remaining quirks it's not substantial enough to suggest as an upgrade.
Overall I think it just barely qualifies as good value for $30. $20 Truthear Hola has better accessories. $25 7Hz Zero can sound more resolving and intimate. $20 KZ EDA Balanced has a better tonal quality, even if it's a bit grainy. D-fi would be close to an allrounder recommendation in the price bracket, if only for the caveat that with the included tips there's a higher chance you won't achieve good fit, or longevity.
Comparing to Truthear Red, in response to OP. There's no competition, Red handles all of my playlist fabulously, from orchestral to hard rock to EDM. But that's comparing a $30 set to a $55 set.
