Short answer: the Sivga Que. It ranks #682 of 1291 in-ear headphones by sound quality, rated 3.7/5, at $69.90; the NF Audio NA3 ranks #725, rated 3.6/5, and costs $69.99, so there is not much of a tradeoff to weigh.
What the Sivga Que does well: The beryllium plated dynamic driver gives full bass about 2.7 dB above target, and the upper mids sit right on target across 24 measurements, so vocals sound clear and natural. The tradeoff: Sub-bass rolls off about 2.5 dB at 30 Hz, a 5.9 dB dip near 6.3 kHz takes some detail out, and a 5 dB peak near 11 kHz can add a little sharpness.
What the NF Audio NA3 does well: A single dynamic IEM with a dual cavity design. Watch for: A 2.33 dB spread from the target shows peaks and dips that better tuned sets avoid.
Buy the Sivga Que. It is rated higher for sound quality than the NF Audio NA3 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.
