Short answer: the 7Hz Eternal. Both are rated 3.6/5 for sound quality (#691 and #706 of 1291 in-ear headphones), and the 7Hz Eternal costs $249 against $269 for the ZiiGaat Doscinco, with sound quality a draw, the lower price decides it.
Why pick the 7Hz Eternal: Crinacle’s measurement gives it a preference score of 69, and squig.link measurements show bass, mids and upper mids all within about 1 dB of target, so voices and instruments sound natural. The tradeoff: Treble above 6 kHz drops 3 to 4 dB below target with an 8.7 dB dip near 10.6 kHz, so cymbals lack sparkle and detail sounds dim.
Why pick the ZiiGaat Doscinco: The median of 14 hobbyist measurements gives it a solid Harman preference score of 69 with a 2.04 dB spread, and its mids sit within about 0.5 dB of target, so vocals and instruments sound natural. The catch: Its 2.04 dB spread is less even than the best measured sets.
Buy the 7Hz Eternal. Both are rated the same for sound quality, and it costs $20 less than the ZiiGaat Doscinco.

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.
