Short answer: the Zuo Drum String Phanta. Both are rated 3.2/5 for sound quality (#1001 and #973 of 1369 in-ear headphones), and the Zuo Drum String Phanta costs $189 against $199 for the Muse HiFi Power, with sound quality a draw, the lower price decides it.
Why pick the Muse HiFi Power: A 14.5mm planar magnetic driver with about 2.3 dB of extra bass and sub-bass that stays within 6 dB of target down to 20 Hz, for a full, warm low end. Watch for: Squig.link measurements show a 12.7 dB peak near 11.9 kHz on top of a 6.5 dB dip near 6.5 kHz, so the lower treble sounds dim while the very top can add a hissy sheen.
Why pick the Zuo Drum String Phanta: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. The catch: An uneven response, 2.8 dB standard deviation from target.
Buy the Zuo Drum String Phanta. Both are rated the same for sound quality, and it costs $10 less than the Muse HiFi Power.

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.
