Short answer: the EPZ G30. It ranks #57 of 971 in-ear headphones by sound quality (rated 4.6/5) at $79.99 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 G30 is the better-sounding option. Four hobbyist measurements on squig.link give it a preference score of 81.5 with a smooth 1.35 dB deviation. The catch: Presence falls about 3.2 dB below target, which tucks vocals slightly behind the instruments.
Why pick 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 G30. It is rated higher for sound quality; the EPZ 530 is no longer sold new.

The Two Headphones In Full
EPZ G30: $79.99 Amazon $79.99 eBay
Pros: Four hobbyist measurements on squig.link give it a preference score of 81.5 with a smooth 1.35 dB deviation. Bass sits about 0.9 dB above target with low mids close behind, giving a warm, full sound that suits bassy tastes. It weighs just 4.4 g per earbud and includes a built-in microphone, so it works for calls as well as music.
Cons: Presence falls about 3.2 dB below target, which tucks vocals slightly behind the instruments. A 5.0 dB peak near 8.1 kHz followed by a 5.6 dB dip near 11.9 kHz gives cymbals an uneven sheen and trims top-end air.
