The case for the Truthear x Crinacle Zero RED: A Harman score of 86 at an entry-level price delivers a well-balanced response with a smooth 1.1 dB deviation. Watch for: Presence from 3 to 6 kHz sits about 2.2 dB below target, so vocals and snare attack can sound a little recessed.

Watch for: 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 Two Headphones In Full

Truthear x Crinacle Zero RED: $64.99 Amazon AliExpress eBay

Pros: A Harman score of 86 at an entry-level price delivers a well-balanced response with a smooth 1.1 dB deviation. Bass and mids track the target closely, and the dual dynamic driver design runs easily from a phone at 17.5 ohms and 117.5 dB per volt. It outscores the Tin HiFi T3 Plus by a clear rating margin at a similar cost. It is a good fit for listeners who like a warm, bass-forward sound.

Cons: Presence from 3 to 6 kHz sits about 2.2 dB below target, so vocals and snare attack can sound a little recessed. A 3.9 dB dip near 10.3 kHz and sub-bass about 1.4 dB light mean cymbals lack some shimmer and the deepest bass has less rumble. It is wired only with no mic or remote listed.

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.
