Short answer: a tie on sound quality. Both are rated 3.7/5 (#682 and #655 of 1291 in-ear headphones) at nearly the same price ($69.90 vs $72.90), so choose on features and fit.
Why pick the Sivga Que: 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 Twistura Sigma does well: Nine hobbyist measurements give this one dynamic plus one balanced armature hybrid a preference score of 70 with a smooth 2.21 dB deviation, so the midrange sounds natural. Watch for: Treble falls about 3 dB and air about 4 dB below target, with an 8.4 dB dip near 11.9 kHz, so cymbals and spacious recordings lose sparkle.
Buy the Sivga Que or the Twistura Sigma on features: they are rated the same for sound quality at close to the same price.

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.
