Short answer: the EPZ G10. It ranks #15 of 971 in-ear headphones by sound quality (rated 4.9/5) at $23.74 and is still sold new; the EPZ 530 ranks #554 (rated 3.5/5) and is discontinued, so it is only an option used.
The EPZ G10 is the better-sounding option. Across 22 hobbyist measurements on squig.link, the G10 tracks the Harman target with only 1.11 dB of deviation and a preference score of 84.7, an exceptionally even result for a single dynamic driver at a budget price. The catch: The presence region around 3 to 6 kHz runs about 1.5 dB low, with a 3.6 dB dip near 6.3 kHz that slightly softens the edge of vocals and snare hits.
The case for the EPZ 530: Five armatures tuned close to the Harman target (score 68 across nineteen measurements), with a modular cable for every common plug. Watch for: Discontinued, so it is mainly found used.
Buy the EPZ G10. It is rated higher for sound quality and still sold new, while the EPZ 530 is discontinued.

The Two Headphones In Full
EPZ G10: $23.74 Amazon $23.74 eBay
Pros: Across 22 hobbyist measurements on squig.link, the G10 tracks the Harman target with only 1.11 dB of deviation and a preference score of 84.7, an exceptionally even result for a single dynamic driver at a budget price. Bass, low mids and upper mids all land within half a decibel of target, so vocals sound natural and bass lines are full without bloat. Sub-bass holds within 1.2 dB of target at 30 Hz, and the 32 ohm, 100 dB sensitivity rating plays comfortably from a phone. It shares its rating with the pricier EPZ Q1 Pro and Intuaura Reference 2019.
Cons: The presence region around 3 to 6 kHz runs about 1.5 dB low, with a 3.6 dB dip near 6.3 kHz that slightly softens the edge of vocals and snare hits. A 4.6 dB peak near 11.9 kHz adds a touch of sparkle that treble sensitive listeners may notice on bright recordings. It is a plain wired set with no microphone or wireless option listed.
