Pros: The median of 16 hobbyist measurements gives it a solid Harman preference score of 71 with a 2.07 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. Bass sits close to target and holds down to 20 Hz, so low end sounds full without bloat. Upper treble lifts about 2.7 dB for extra air and sparkle. It uses 1 x 10mm dynamic + 3 x balanced armature + 1 x MEMS with an easy 29 ohm load.
Cons: Presence sits about 3.4 dB low with a 6.5 dB dip near 6.1 kHz, so vocals and instruments lose some bite.
