Short answer: the ZiiGaat Estrella. Both are rated 4.4/5 for sound quality (#133 and #140 of 1291 in-ear headphones), and the ZiiGaat Estrella costs $299 against $328 for the Melody Wings Neptune, with sound quality a draw, the lower price decides it.
What the Melody Wings Neptune does well: Across 6 squig.link measurements it scores 78.9 with a 1.48 dB spread, and its bass and mids stay within about 1 dB of target, so voices and instruments keep a natural balance. The catch: The 5.6 dB peak near 8.2 kHz can make sibilance and bright recordings sound edgy at higher volumes.
The case for the ZiiGaat Estrella: The median of 8 squig.link measurements shows one of the smoothest responses around, a 1.3 dB spread with a preference score of 79.0. The catch: Presence is about 3 dB low between 3 and 6 kHz, with a 4.7 dB dip near 5.8 kHz, so vocals and snare attack lose some bite and edge.
Buy the ZiiGaat Estrella. Both are rated the same for sound quality, and it costs $29 less than the Melody Wings Neptune.

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.
