Short answer: the FiiO FH7S. It ranks #939 of 1291 in-ear headphones by sound quality, rated 3.2/5, at $299.99; the Punch Audio Martilo ranks #967, rated 3.1/5, and costs $329, so there is little reason to consider the other one.
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.
The case for the Punch Audio Martilo: Bass is lifted about 2.5 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. The tradeoff: A 5 dB peak near 11.9 kHz can make cymbals and sibilance sound sharp.
Buy the FiiO FH7S. It is rated higher for sound quality than the Punch Audio Martilo and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

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.
