Short answer: the EPZ Q1 Pro. Both are rated 4.9/5 for sound quality (#12 and #9 of 450 in-ear headphones), and the EPZ Q1 Pro costs $39.99 against $49.99 for the EPZ G20, and with sound quality even, the cheaper one is the better buy.
Why pick the EPZ G20: 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 catch: 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 Q1 Pro: For a budget single dynamic in-ear, the median of 29 hobbyist measurements is impressive: a preference score of 85 and an average deviation of about 1 dB from the Harman target. Watch for: Sub-bass sits about 1.6 dB under target, so deep electronic bass has slightly less rumble than bass fans may want.
Buy the EPZ Q1 Pro. Both are rated the same for sound quality, and it costs $10 less than the EPZ G20.

The Two Headphones In Full
EPZ G20: $49.99 Amazon 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.

EPZ Q1 Pro: $39.99 Amazon eBay
Pros: For a budget single dynamic in-ear, the median of 29 hobbyist measurements is impressive: a preference score of 85 and an average deviation of about 1 dB from the Harman target. Midrange and treble bands track the target within about 1 dB, so voices and instruments sound natural rather than hyped. It shares its rating with the EPZ G20 and Intuaura Reference 2019 at a similar price.
Cons: Sub-bass sits about 1.6 dB under target, so deep electronic bass has slightly less rumble than bass fans may want. Sensitivity of 100 dB/Vrms at 32 ohms is low for an in-ear, so expect to turn a phone up more than usual. A 3.4 dB dip near 6.3 kHz and a 4.6 dB peak near 11.9 kHz add a little unevenness in the treble.
