Fiio FH5
Similar sound balancing and bass impact. DB3 sounds similar to the Fiio FH5.
Ya I am comparing a $20 earphone to a $260 one!
Too quick, my man. Main peaks are at a different point (2k vs 3k), which causes quite dramatic perceptual differences in sound presentation. Also, @darmanastartes plot is not IEC711 compliant. Even with a RECD conversion, it's not directly comparable. There will be high frequency resonance shifts that will skew the interpretation.
