Short answer: the Hidizs MK12 Turris. Both are rated 3.3/5 for sound quality (#894 and #911 of 1291 in-ear headphones), and the Hidizs MK12 Turris costs $79 against $89 for the Tangzu Fudu, with sound quality a draw, the lower price decides it.
What the Hidizs MK12 Turris does well: A broadly balanced tuning with a preference score of 66 against the Harman target. The tradeoff: Treble about 4 dB below target from 3 to 10 kHz, which can sound dull or veiled next to brighter headphones.
What the Tangzu Fudu does well: Bass is lifted about 2.7 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Watch for: Presence sits about 3.7 dB low with a 5.9 dB dip near 5.9 kHz, so vocals and instruments lose some bite.
Buy the Hidizs MK12 Turris. Both are rated the same for sound quality, and it costs $10 less than the Tangzu Fudu.

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.
