Short answer: the EPZ G10. It ranks #11 of 450 in-ear headphones by sound quality, rated 4.9/5, at $23.74; the EPZ 550 ranks #227, rated 4.1/5, and costs $519.99, so there is not much of a tradeoff to weigh.
The EPZ G10 is the better-sounding choice. 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. Watch for: 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.
Buy the EPZ G10. It is rated higher for sound quality than the EPZ 550 and costs less, so only choose the other one for a particular feature it does better.

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.
