Short answer: a tie on sound quality. Both are rated 4.7/5 (#29 and #27 of 450 in-ear headphones), so choose on features and fit.
The case for the SeeAudio Yume: A preference score of 82 in HypetheSonics’ measurement with a smooth 1.49 dB standard deviation from target. The catch: Presence sits about 3.2 dB below target from 3 to 6 kHz with a 4.3 dB dip near 4.3 kHz, so vocals and guitars lose a little bite, while a 4.7 dB peak near 8.5 kHz can make some cymbals stand out.
Why pick the Truthear Hexa: A preference score of 82 in oratory1990’s measurement and a 1.58 dB deviation put this hybrid of one dynamic driver and three balanced armatures very close to the Harman target. Watch for: The presence region from 3 to 6 kHz sits 2.6 dB under target with a 4 dB dip near 4.5 kHz, which pushes vocals and guitars slightly back.
Buy the SeeAudio Yume or the Truthear Hexa on features: they are rated the same for sound quality at close to the same price.

SeeAudio Yume: $169.00 Linsoul eBay
Pros: A preference score of 82 in HypetheSonics’ measurement with a smooth 1.49 dB standard deviation from target. Bass reaches 20 Hz within about 1 dB of target and the mids from 200 Hz to 3 kHz stay within 0.2 dB, so the sound is balanced and natural. Its hybrid of one dynamic driver and two balanced armatures rates above the Final Audio A4000 and Shuoer S12.
Cons: Presence sits about 3.2 dB below target from 3 to 6 kHz with a 4.3 dB dip near 4.3 kHz, so vocals and guitars lose a little bite, while a 4.7 dB peak near 8.5 kHz can make some cymbals stand out. The higher rated Truthear Nova sells at about the same price.

Truthear Hexa AliExpress eBay
Pros: A preference score of 82 in oratory1990’s measurement and a 1.58 dB deviation put this hybrid of one dynamic driver and three balanced armatures very close to the Harman target. Bass from 60 to 200 Hz is within 0.2 dB of target and sub-bass is just 1.7 dB down at 30 Hz, so low end is full but controlled. The 20.5 ohm impedance and 120 dB/Vrms sensitivity make it easy to drive from a phone.
Cons: The presence region from 3 to 6 kHz sits 2.6 dB under target with a 4 dB dip near 4.5 kHz, which pushes vocals and guitars slightly back. A 4.7 dB peak near 8.3 kHz and extra air above 10 kHz can make sibilance stand out on bright recordings.
