Short answer: the Aoshida E20. It ranks #40 of 1291 in-ear headphones by sound quality, rated 4.7/5, at $22.99; the Shanling Tino ranks #74, rated 4.6/5, and costs $23.99, which makes this an easy call rather than a real tradeoff.
Why pick the Aoshida E20: Across six hobbyist measurements on squig.link, the E20 reaches a preference score of 82.6 with a smooth 1.13 dB deviation from target. Watch for: A 6 dB peak near 8.4 kHz and treble about 2.1 dB above target from 6 to 10 kHz can make sibilance and hi hats sound sharp on bright recordings.
What the Shanling Tino does well: Five squig.link measurements give it a preference score of 80.8 with 1.37 dB of deviation, and its dual dynamic drivers keep sub-bass within a fraction of a dB of target to 30 Hz. The catch: A 5.2 dB dip near 10.6 kHz and treble about 1.2 dB under target trim some sparkle from cymbals and ambience.
Buy the Aoshida E20. It is rated higher for sound quality than the Shanling Tino and costs less, which makes it the one to get unless you need something the other one does better.

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.
