Pros: The median of 14 hobbyist measurements gives it a solid Harman preference score of 70 with a 2.10 dB spread, and its mids sit within about 0.6 dB of target, so vocals and instruments sound natural. Bass is lifted about 2.2 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. It uses 1 x planar magnetic with an easy 15 ohm load.
Cons: A 6.1 dB peak near 8.4 kHz can make cymbals and sibilance sound sharp.
