Short answer: a tie on sound quality. Both are rated 3.8/5 (#558 and #545 of 1291 in-ear headphones) at nearly the same price ($39.99 vs $39), so choose on features and fit.
Why pick the Rose Technics Ceramics: A broadly balanced tuning with a preference score of 72 against the Harman target. The tradeoff: An uneven response, 2.2 dB standard deviation from target.
What the Tin HiFi C5 does well: The median of 13 hobbyist measurements gives it a solid Harman preference score of 72 with a 2.05 dB spread. Watch for: Presence sits about 3.4 dB low with an 8.2 dB dip near 10.3 kHz, so vocals and instruments lose some bite.
Buy the Rose Technics Ceramics or the Tin HiFi C5 on features: they are rated the same for sound quality at close to the same price.

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.
