Short answer: the Tin HiFi T4 Plus. It ranks #116 of 1291 in-ear headphones by sound quality, rated 4.5/5, at $69; the Truthear x Crinacle Zero ranks #127, rated 4.4/5, at $67.49. Close enough in price that the sound-quality gap is the deciding factor.
Why pick the Tin HiFi T4 Plus: Across ten squig.link measurements it scores 80.0 for preference, with sub-bass sitting right on target down to 30 Hz and a 2.2 dB bass lift that gives drums and electric bass a satisfying thump. Watch for: Treble climbs to a 4.8 dB peak near 11.9 kHz, which some listeners hear as hiss or shimmer that sits above the music.
What the Truthear x Crinacle Zero does well: Oratory1990’s measurement gives it a preference score of 79 with a 1.61 dB deviation, and its two dynamic drivers stay within about 1.3 dB of target from 60 Hz up to 10 kHz. The tradeoff: A 4.5 dB peak near 8 kHz and 2.4 dB of extra air above 10 kHz give it a brighter tilt than target, so sibilant vocals and cymbals can sound edgy.
Buy the Tin HiFi T4 Plus. It is rated higher for sound quality, and the $1.51 you would save on the Truthear x Crinacle Zero does not close the gap.

Frequency Response Compared
Both headphones’ measurements overlaid on the Harman target. Above the target sounds louder in that range, below it quieter. Each curve is the median of several independent measurements, shifted so its 500 Hz to 2 kHz average sits at 0 dB, so only the tuning is compared.
