Pros: A single 14.5 mm planar magnetic driver earns a preference score of 76 in crinacle’s measurement with a low 1.76 dB deviation. Sub-bass and bass run about 1.5 dB above target, 1.6 dB over at 30 Hz, so it suits listeners who want a warm, full sound with real low-end depth. The midrange from 200 Hz to 3 kHz is essentially on target, keeping voices clear.
Cons: Hobbyist measurements on squig.link show a 4.1 dB dip near 6.7 kHz that blunts snare snap and sibilance, followed by a 4.7 dB peak near 11.9 kHz that adds some airy sizzle. It is wired only and lists no microphone.
