Short answer: the Letshuoer DX1. It ranks #850 of 1291 in-ear headphones by sound quality, rated 3.4/5, at $109; the ARTTI T10 Pro ranks #907, rated 3.3/5, at $109. The price gap is small enough that the sound-quality ranking should decide it.
What the Letshuoer DX1 does well: Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural. The catch: Presence sits about 6.2 dB low with an 8.9 dB dip near 10.3 kHz, so vocals and instruments lose some bite.
Why pick the ARTTI T10 Pro: Bass is lifted about 3 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Watch for: Presence sits about 4 dB low with a 4.9 dB dip near 6.3 kHz, so vocals and instruments lose some bite.
Buy the Letshuoer DX1. It is rated higher for sound quality than the ARTTI T10 Pro at the same price, 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.
