Short answer: the MEE Audio M6 Pro. Both are rated 3.8/5 for sound quality (#28 and #27 of 68 in-ear headphones), and the MEE Audio M6 Pro costs $39.99 against $65.99 for the KZ ZAX, so with nothing between them on sound quality, price settles it.
What the KZ ZAX does well: A preference score of 71 in crinacle’s measurement comes from a hybrid design with one dynamic driver and seven balanced armatures. Watch for: The response sits 2.3 dB from the target on average, so some coloration remains despite the eight drivers.
The case for the MEE Audio M6 Pro: A preference score of 71 in crinacle’s measurement is a decent result for a single 10mm dynamic driver. The catch: The 100 dB/mW sensitivity is the lowest in this group, so it needs a little more volume than the hybrids.
Buy the MEE Audio M6 Pro. Both are rated the same for sound quality, and it costs $26 less than the KZ ZAX.

KZ ZAX: $65.99 Amazon eBay
Pros: A preference score of 71 in crinacle’s measurement comes from a hybrid design with one dynamic driver and seven balanced armatures. At 24 ohms and 113 dB the sensitivity is very high, so any phone or dongle drives it easily. The slightly warm tilt keeps treble from turning harsh.
Cons: The response sits 2.3 dB from the target on average, so some coloration remains despite the eight drivers. It also costs noticeably more than the CCA C12 for the same rating, and the Tin HiFi T4 rates higher with a single dynamic driver.

MEE Audio M6 Pro: $39.99 Amazon eBay
Pros: A preference score of 71 in crinacle’s measurement is a decent result for a single 10mm dynamic driver. At 16 ohms and 100 dB/mW it is simple to drive from a phone, and the slightly warm tilt gives a smooth, easy listen. Its rating matches the CCA C12 and KZ ZAX.
Cons: The 100 dB/mW sensitivity is the lowest in this group, so it needs a little more volume than the hybrids. The 2.2 dB deviation from the target leaves audible coloration, and the 7Hz x Crinacle Zero 2 rates higher at a lower price.
