Balanced subbass-focused tuning that borders the fine line between technical and boring, well extended treble that remains free of sibilance The lower midrange does not sound the most natural despite how funny squiggly lines look

Best Harman IEM under $600 (my unit is less harman), smooth and natural, great layering and tech, bass texture could be better/not as good as Oracle MK3, but overall very balanced and great all-rounder, also, amazing unboxing and accessories
