Short answer: a tie on sound quality. Both are rated 4.7/5 (#35 and #30 of 450 in-ear headphones) at nearly the same price ($22.99 vs $21.99), so choose on features and fit.
Why pick the DDHiFi Janus 3: For a very low cost single dynamic in-ear, it measures a preference score of 82 in the median of four hobbyist measurements on squig.link. The tradeoff: A 3.3 dB dip near 10.9 kHz dulls some cymbal shimmer, and the downward tilt toward bass makes it less suited to listeners who like a crisp, detailed top end.
Why pick the KZ Gale: Squig.link measurements, the median of six hobbyist samples, give it a preference score of 82, solid for a very inexpensive single dynamic in-ear. The tradeoff: Sub-bass sits about 1.8 dB under target, so deep electronic bass has less rumble than bassier rivals.
Buy the DDHiFi Janus 3 or the KZ Gale on features: they are rated the same for sound quality at close to the same price.

The Two Headphones In Full
DDHiFi Janus 3: $22.99 Amazon eBay
Pros: For a very low cost single dynamic in-ear, it measures a preference score of 82 in the median of four hobbyist measurements on squig.link. Sub-bass and bass sit about 1.5 to 2 dB above target, so it delivers a warm, bass rich sound that bass lovers will enjoy. At 14 ohms and 122 dB/Vrms it plays loudly from a phone, and each earbud weighs just 5.5 g.
Cons: A 3.3 dB dip near 10.9 kHz dulls some cymbal shimmer, and the downward tilt toward bass makes it less suited to listeners who like a crisp, detailed top end. Only four samples were measured, so the figures carry more uncertainty than for widely measured models.

KZ Gale: $21.99 Amazon eBay
Pros: Squig.link measurements, the median of six hobbyist samples, give it a preference score of 82, solid for a very inexpensive single dynamic in-ear. Bass and lower midrange sit close to target with a slight upper bass lift, giving a warm, relaxed tone. Sensitivity of 107 dB/mW at 24 ohms means a phone drives it easily. It shares its rating with the KZ EDZ and DDHiFi Janus 3 at a similar price.
Cons: Sub-bass sits about 1.8 dB under target, so deep electronic bass has less rumble than bassier rivals. The presence band runs nearly 2 dB low with a 2.8 dB dip near 3.5 kHz, pushing vocals slightly back, and its 1.35 dB average deviation is less even than the best in-ears.
