Short answer: the EPZ G10. It ranks #10 of 263 in-ear headphones by sound quality, rated 4.9/5, at $23.74; the EPZ G30 ranks #41, rated 4.6/5, and costs $79.99, so there is little reason to consider the other one.
The EPZ G10 is the better-sounding pick. 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 tradeoff: 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 G30: Four hobbyist measurements on squig.link give it a preference score of 81.5 with a smooth 1.35 dB deviation. The tradeoff: Presence falls about 3.2 dB below target, which tucks vocals slightly behind the instruments.
Buy the EPZ G10. It is rated higher for sound quality than the EPZ G30 and costs less, which makes it the one to get unless you need something the other one does better.

The Two Headphones In Full
EPZ G10: $23.74 Amazon 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.

EPZ G30: $79.99 Amazon 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.
