Short answer: the Truthear Zero Blue 2. It ranks #13 of 450 in-ear headphones by sound quality, rated 4.9/5, at $69.99; the Shuoer Galileo ranks #33, rated 4.7/5, at $69.99. Close enough in price that the sound-quality gap is the deciding factor.
What the Truthear Zero Blue 2 does well: The Zero Blue 2 uses two dynamic drivers and, across fourteen hobbyist measurements on squig.link, scores 85 for preference with about 1 dB of unevenness. Watch for: The air band runs about 3.9 dB above target and a 4.5 dB peak sits near 8.1 kHz, which can make sibilance and cymbals stand out on bright mixes.
What the Shuoer Galileo does well: The median of 12 hobbyist measurements on squig.link gives the Galileo a preference score of 82 with a smooth 1.21 dB deviation. Watch for: The presence region from 3 to 6 kHz sits about 4.1 dB low, which pushes vocals and guitar attack back behind the bass.
Buy the Truthear Zero Blue 2. It is rated higher for sound quality than the Shuoer Galileo at the same price, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Headphones In Full
Truthear Zero Blue 2: $69.99 Amazon eBay
Pros: The Zero Blue 2 uses two dynamic drivers and, across fourteen hobbyist measurements on squig.link, scores 85 for preference with about 1 dB of unevenness. Its warm tilt and sub-bass about 1 dB above target give it full, punchy low end, while mids stay neutral. Sensitivity of 119.5 dB/Vrms makes it effortless to drive from a phone.
Cons: The air band runs about 3.9 dB above target and a 4.5 dB peak sits near 8.1 kHz, which can make sibilance and cymbals stand out on bright mixes. The very low 5.8 ohm impedance can pick up hiss from noisy sources, and the EPZ G20 earns the same rating for less money.

Shuoer Galileo: $69.99 Amazon eBay
Pros: The median of 12 hobbyist measurements on squig.link gives the Galileo a preference score of 82 with a smooth 1.21 dB deviation. Bass runs about 3.3 dB above target, giving a warm, punchy low end that suits bassy and warm listeners, and sub-bass stays close to target at 30 Hz. The 104 dB/mW sensitivity at 14 ohms makes it easy to drive from a phone.
Cons: The presence region from 3 to 6 kHz sits about 4.1 dB low, which pushes vocals and guitar attack back behind the bass. A 6.5 dB peak near 8.4 kHz and a 5.5 dB dip near 11 kHz make the treble uneven. It is rated below similarly priced rivals such as the EPZ G20 and ThieAudio Legacy 4.
