Short answer: the KZ Saga Balanced. It ranks #734 of 1291 in-ear headphones by sound quality, rated 3.6/5, at $25.99; the KZ EDX Ultra ranks #871, rated 3.4/5, at $24.99. With prices this close, go by the sound-quality ranking rather than the cost.
Why pick the KZ Saga Balanced: The Balanced tuning of the very cheap KZ Saga, a single dynamic IEM in a zinc alloy shell. The catch: Bass sits about 2.8 dB above target, a bass heavy balance.
The case for the KZ EDX Ultra: Bass is lifted about 3.2 dB with extension to 20 Hz, giving kick drums and bass lines extra weight. Watch for: Presence sits about 3.1 dB low with a 6.8 dB dip near 6.7 kHz, so vocals and instruments lose some bite.
Buy the KZ Saga Balanced. It is rated higher for sound quality, and saving $1 with the KZ EDX Ultra does not make up for the sound-quality gap.

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.
