#79 KZ Duonic: $34.99 Amazon eBay
Pros: Five squig.link measurements give the Duonic a preference score of 79.2, a strong showing for a cheap dynamic and planar hybrid. Bass sits about 2.7 dB above target with sub-bass extending to 20 Hz, so it delivers warm, energetic low end for V-shaped tastes. It costs less than the equally rated Kefine Klean and Ooopusx OP24.
Cons: Air above 10 kHz runs about 5.2 dB hot with a 5.5 dB peak near 8.1 kHz, so cymbals can turn splashy and bright tracks fatiguing. A 3.5 dB dip near 3.8 kHz and a presence band 2 dB below target recess vocals slightly behind the boosted bass and treble.
