Short answer: the EarAcoustic Audio SPA Limited Edition. Both are rated 4.0/5 for sound quality (#440 and #386 of 1291 in-ear headphones), and the EarAcoustic Audio SPA Limited Edition costs $429.90 against $449 for the Hisenior Mega7, with sound quality a draw, the lower price decides it.
Why pick the EarAcoustic Audio SPA Limited Edition: A broadly balanced tuning with a preference score of 74 against the Harman target. Watch for: Treble about 2 dB above target from 3 to 10 kHz, which can sound sharp or tiring at higher volume.
Why pick the Hisenior Mega7: The median of 18 hobbyist measurements gives it a solid Harman preference score of 74 with a 1.65 dB spread. The tradeoff: Presence sits about 5 dB low with a 5.6 dB dip near 5.6 kHz, so vocals and instruments lose some bite.
Buy the EarAcoustic Audio SPA Limited Edition. Both are rated the same for sound quality, and it costs $19.10 less than the Hisenior Mega7.

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.
