Short answer: the Hidizs MS5. It ranks #909 of 1291 in-ear headphones by sound quality, rated 3.3/5, at $299; the FiiO FH7S ranks #939, rated 3.2/5, and costs $299.99, so there is not much of a tradeoff to weigh.
The case for the Hidizs MS5: Lower mids sit within about 0.7 dB of target, keeping voices and guitars natural. Watch for: Presence sits about 3.4 dB low with a 12.7 dB dip near 11.9 kHz, so vocals and instruments lose some bite.
The case for the FiiO FH7S: Oratory1990 measured bass about 4.6 dB above the Harman target, so kick drums and bass lines hit with real weight for a hybrid built around a 13.6mm dynamic driver and four balanced armatures. The catch: Low mids run 2.4 dB hot on top of the bass lift, which can make male vocals and bass instruments thick.
Buy the Hidizs MS5. It is rated higher for sound quality than the FiiO FH7S and costs less, so only choose the other one for a particular feature it 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.
