Short answer: the CCA PLA13, though neither ranks well in its class. It ranks #422 of 450 in-ear headphones by sound quality, rated 2.3/5, at $88; the Zero Audio Duoza ZH-DWX10 ranks #428, rated 2.1/5, and costs $89, so there is not much of a tradeoff to weigh. Both are rated below 3.0/5 among the 450 in-ear headphones, so if sound quality matters, consider the Intuaura Reference 2019 instead, ranked #5 at $34.99.
The case for the CCA PLA13: A 13.2mm planar magnetic driver at 16 ohms and 100 dB sensitivity makes it easy to drive straight from a phone. The tradeoff: The top octave is pushed hard, with air about 9.3 dB above target and a 9 dB peak near 10.7 kHz, so cymbals and sibilance can turn splashy and fatiguing.
Why pick the Zero Audio Duoza ZH-DWX10: A dual dynamic driver design at 20 ohms and 100 dB/mW plays at good volume from a phone. The catch: A preference score of 51 in crinacle’s measurement places it well off the response most listeners prefer, so expect a clearly colored sound.
Buy the CCA PLA13. It is rated higher for sound quality than the Zero Audio Duoza ZH-DWX10 and costs less, so only choose the other one for a particular feature it does better.

The Two Headphones In Full
CCA PLA13: $88.00 Amazon eBay
Pros: A 13.2mm planar magnetic driver at 16 ohms and 100 dB sensitivity makes it easy to drive straight from a phone. Across eleven hobbyist measurements on squig.link both sub-bass and bass sit about 3.4 dB above target and extend fully to 20 Hz, which suits listeners who want a bassy, warm profile with plenty of rumble.
Cons: The top octave is pushed hard, with air about 9.3 dB above target and a 9 dB peak near 10.7 kHz, so cymbals and sibilance can turn splashy and fatiguing. A 6.3 dB dip near 6.9 kHz sits right below that peak, making the treble uneven rather than smoothly bright. The iBasso IT01 rates higher and costs less.

Zero Audio Duoza ZH-DWX10: $89.00 Amazon eBay
Pros: A dual dynamic driver design at 20 ohms and 100 dB/mW plays at good volume from a phone. Its rating matches the 1MORE Penta Driver for less money and sits above the Etymotic ER3SE and KZ ASX, which cost more.
Cons: A preference score of 51 in crinacle’s measurement places it well off the response most listeners prefer, so expect a clearly colored sound. Better tuned in-ears are easy to find for similar money.
