Short answer: the CCA Phoenix. It ranks #37 of 450 in-ear headphones by sound quality, rated 4.7/5, at $33.99; the Tin HiFi C2 Mech Warrior ranks #55, rated 4.6/5, and costs $39, so there is not much of a tradeoff to weigh.
What the CCA Phoenix does well: 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.
The case for the Tin HiFi C2 Mech Warrior: The median of nine squig.link measurements gives it a preference score of 80.2 with a tidy 1.44 dB deviation, and sub-bass stays within about 1 dB of target to 30 Hz for solid low end rumble. Watch for: Air above 10 kHz runs about 4.6 dB hot, peaking 6.8 dB near 11.9 kHz, which can make cymbals and hiss on older recordings sound sharp.
Buy the CCA Phoenix. It is rated higher for sound quality than the Tin HiFi C2 Mech Warrior and costs less, so it is the default pick unless a specific strength of the other one matters more to you.

The Two Headphones In Full
CCA Phoenix: $33.99 Amazon eBay
Pros: 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. Bass runs about 2.2 dB above target from 60 to 200 Hz, giving drums and bass guitar a warm, full body. Its 108 dB sensitivity at 33 ohms means a phone drives it easily.
Cons: 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. The low mids run about 1.3 dB heavy, slightly thickening male vocals. It is rated equal to cheaper models like the Aoshida E20 and KZ Gale, so it offers no rating advantage for the extra cost.

Tin HiFi C2 Mech Warrior: $39.00 Amazon eBay
Pros: The median of nine squig.link measurements gives it a preference score of 80.2 with a tidy 1.44 dB deviation, and sub-bass stays within about 1 dB of target to 30 Hz for solid low end rumble. A 2 dB bass lift adds punch without clouding the midrange, which sits almost exactly on target through the upper mids. At 104 dB/mW and 32 ohms it gets plenty loud from a phone.
Cons: Air above 10 kHz runs about 4.6 dB hot, peaking 6.8 dB near 11.9 kHz, which can make cymbals and hiss on older recordings sound sharp. A small 2.9 dB dip near 6.3 kHz leaves some instruments slightly recessed in the presence region.
