Short answer: the EPZ G20. It ranks #13 of 971 in-ear headphones by sound quality (rated 4.9/5) at $49.99 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 G20 is the better-sounding pick. The G20 is one of the most accurate inexpensive in-ears measured, with a preference score of 86 and under 1 dB of unevenness in the median of twelve hobbyist measurements on squig.link. The tradeoff: A 6.3 dB peak near 11.9 kHz adds extra air that can make some recordings sound a little hissy or splashy.
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. The catch: Discontinued, so it is mainly found used.
Buy the EPZ G20. It is rated higher for sound quality; the EPZ 530 is no longer sold new.

The Two Headphones In Full
EPZ G20: $49.99 Amazon $49.99 eBay
Pros: The G20 is one of the most accurate inexpensive in-ears measured, with a preference score of 86 and under 1 dB of unevenness in the median of twelve hobbyist measurements on squig.link. Bass, midrange and lower treble all land within about 1 dB of target, and sub-bass stays full down to 20 Hz. It matches the rating of the costlier Truthear Zero Blue 2 and includes an inline microphone.
Cons: A 6.3 dB peak near 11.9 kHz adds extra air that can make some recordings sound a little hissy or splashy. The EPZ Q1 Pro earns the same rating for a bit less money, and the 100 dB sensitivity figure is unremarkable, though still fine for a phone.
