Short answer: the Simgot EW100P. It ranks #37 of 1291 in-ear headphones by sound quality, rated 4.8/5, at $32.62; the CCA Phoenix ranks #53, rated 4.7/5, and costs $33.99, so there is little reason to consider the other one.
The case for the Simgot EW100P: In oratory1990’s measurement it earns a preference score of 83 with a deviation of only 1.49 dB, so its single 10mm dynamic driver tracks the Harman target unusually closely. The catch: A 5.8 dB dip near 9.7 kHz and treble running about 2.4 dB under target between 6 and 10 kHz soften cymbals and string texture, while the 10 to 16 kHz air region is 3.6 dB hot.
The case for the CCA Phoenix: The median of 14 hobbyist measurements on squig.link gives the Phoenix a preference score of 81.7, with the 1.5 to 12 kHz range staying within about 2.4 dB of target. Watch for: Air above 10 kHz is about 4.1 dB above target, which adds a bright sheen that some listeners will find too crisp on harsh recordings.
Buy the Simgot EW100P. It is rated higher for sound quality than the CCA Phoenix and costs less, so only choose the other one for a particular feature it does better.

Frequency Response Compared
Both headphones’ measurements overlaid on the Harman target. Above the target sounds louder in that range, below it quieter. Each curve is the median of several independent measurements, shifted so its 500 Hz to 2 kHz average sits at 0 dB, so only the tuning is compared.
