Short answer: a tie on sound quality. Both are rated 3.1/5 (#1024 and #1053 of 1369 in-ear headphones) at nearly the same price ($99 vs $99.99), so choose on features and fit.
What the Letshuoer S08 does well: Its 13 mm planar driver keeps bass full and extended to 20 Hz across 29 measurements, with lower mids close to target. Watch for: The presence region is about 6 dB low with a 7.7 dB dip near 3.5 kHz, so vocals sound recessed and lack clarity.
What the Tipsy M1 does well: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. Watch for: Treble about 5 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
Buy the Letshuoer S08 or the Tipsy M1 on features: they are rated the same for sound quality at close to the same price.

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.
