#12 Truthear Zero Blue 2: $69.99 Amazon eBay
Pros: The Zero Blue 2 uses two dynamic drivers and, across fourteen hobbyist measurements on squig.link, scores 85 for preference with about 1 dB of unevenness. Its warm tilt and sub-bass about 1 dB above target give it full, punchy low end, while mids stay neutral. Sensitivity of 119.5 dB/Vrms makes it effortless to drive from a phone.
Cons: The air band runs about 3.9 dB above target and a 4.5 dB peak sits near 8.1 kHz, which can make sibilance and cymbals stand out on bright mixes. The very low 5.8 ohm impedance can pick up hiss from noisy sources, and the EPZ G20 earns the same rating for less money.
