Short answer: the Tin HiFi C2. It ranks #61 of 1291 in-ear headphones by sound quality, rated 4.6/5, at $59.99; the Tin HiFi T4 Plus ranks #116, rated 4.5/5, and costs $69, so there is little reason to consider the other one.
The case for the Tin HiFi C2: Across 15 squig.link measurements it reaches a preference score of 81.6 with a 1.42 dB deviation, close to neutral with a slight warm lean. Watch for: The 10 to 16 kHz air band runs about 5 dB above target with a 6.2 dB peak near 11.9 kHz, which can make cymbals and hi hats sound a bit sharp to treble sensitive ears.
Why pick the Tin HiFi T4 Plus: Across ten squig.link measurements it scores 80.0 for preference, with sub-bass sitting right on target down to 30 Hz and a 2.2 dB bass lift that gives drums and electric bass a satisfying thump. Watch for: Treble climbs to a 4.8 dB peak near 11.9 kHz, which some listeners hear as hiss or shimmer that sits above the music.
Buy the Tin HiFi C2. It is rated higher for sound quality than the Tin HiFi T4 Plus and costs less, which makes it the one to get unless you need something the other one 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.
