I don't regret it, they sound perfect. They highlight what is just and necessary to make it sound flat, but enough equalized so as not to become boring, the low frequencies have presence but not for basshead (because I don't like iems either), they also have exquisite sub-basses, clear mids that don't dirty the mix (the most annoying noises are found at those frequencies, which is incredibly not the case), elements such as a guitar or a snare stand out for their clarity. They have extensive highs without being sibilant, I am somewhat sensitive to these frequencies, however I did not experience fatigue in hours of listening, but I cannot guarantee that someone more sensitive than me will possibly dislike it. Very good image, spacious soundstage without sounding like an artificial or forced reverb that doesn't exist. About ergonomics, they are very comfortable (I should mention that I consider myself to have average-sized ears).
Something negative? Nothing that is not solvable. It would be the package that it comes with, since it is a synthetic leather case (without a box) where a small cleaning brush comes, a pair of ear tips (curiously they resemble the low-end sony ear tips), it comes without manual, instructions, warranty, or any text or paper. Regarding the cable, these were already connected to the iems, my impressions about these were quite positive, they are solid, but they do not give me the feeling of being high-end for the price.
Everything mentioned, the packaging, the ear tips and the cable, can be improved by oneself, so here comes the big question, are they worth the price? Absolutely, at the end of the day the most important part is the iems and the drivers that they come with that sound spectacular (anyway I usually change the cable that the iems come with, regardless of the brand to improve my setup) 10/10.
