Short answer: the EPZ G20. Both are rated 4.9/5 for sound quality (#9 and #7 of 450 in-ear headphones), and the EPZ G20 costs $49.99 against $64.99 for the Truthear x Crinacle Zero RED, and with sound quality even, the cheaper one is the better buy.
The case for the EPZ G20: The G20 is one of the most accurate inexpensive in-ears measured, with a preference score of 86 and under 1 dB of unevenness in the median of twelve hobbyist measurements on squig.link. The catch: A 6.3 dB peak near 11.9 kHz adds extra air that can make some recordings sound a little hissy or splashy.
What the Truthear x Crinacle Zero RED does well: 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.
Buy the EPZ G20. Both are rated the same for sound quality, and it costs $15 less than the Truthear x Crinacle Zero RED.

The Two Headphones In Full
EPZ G20: $49.99 Amazon eBay
Pros: The G20 is one of the most accurate inexpensive in-ears measured, with a preference score of 86 and under 1 dB of unevenness in the median of twelve hobbyist measurements on squig.link. Bass, midrange and lower treble all land within about 1 dB of target, and sub-bass stays full down to 20 Hz. It matches the rating of the costlier Truthear Zero Blue 2 and includes an inline microphone.
Cons: A 6.3 dB peak near 11.9 kHz adds extra air that can make some recordings sound a little hissy or splashy. The EPZ Q1 Pro earns the same rating for a bit less money, and the 100 dB sensitivity figure is unremarkable, though still fine for a phone.

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.
