Short answer: the Agasound Sublimation. Both are rated 4.0/5 for sound quality (#437 and #410 of 1291 in-ear headphones), and the Agasound Sublimation costs $115 against $125 for the Tin HiFi T5S, so with nothing between them on sound quality, price settles it.
The case for the Agasound Sublimation: A broadly balanced tuning with a preference score of 74 against the Harman target. The tradeoff: Treble about 3 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
What the Tin HiFi T5S does well: The median of 13 hobbyist measurements gives it a solid Harman preference score of 74 with a 1.83 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. Watch for: A 5.2 dB peak near 8.2 kHz can make cymbals and sibilance sound sharp.
Buy the Agasound Sublimation. Both are rated the same for sound quality, and it costs $10 less than the Tin HiFi T5S.

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.
