Short answer: a tie on sound quality. Both are rated 4.5/5 (#86 and #66 of 450 in-ear headphones) at nearly the same price ($39 vs $39), so choose on features and fit.
The case for the Tin HiFi C2 2025: The median of 15 squig.link measurements gives it a preference score of 79.3 and a smooth 1.39 dB spread, a strong result from a single 10 mm dynamic driver. Watch for: A 7.7 dB peak near 11.9 kHz can add a hint of tizz to cymbals and hi-hats.
What the Tin HiFi T2 DLC does well: Fifteen hobbyist measurements on squig.link put it at a preference score of 80.4 with a neutral overall tilt. The tradeoff: Sub-bass runs about 2.3 dB below target and 2.7 dB down at 30 Hz, so the deepest bass notes lack weight.

Tin HiFi C2 2025: $39.00 Amazon eBay
Pros: The median of 15 squig.link measurements gives it a preference score of 79.3 and a smooth 1.39 dB spread, a strong result from a single 10 mm dynamic driver. Bass rises about 2 dB above target between 60 and 200 Hz with sub-bass right on target, giving a warm, punchy low end that suits bass lovers. Its 32 ohm load is easy for phones and dongles.
Cons: A 7.7 dB peak near 11.9 kHz can add a hint of tizz to cymbals and hi-hats. Presence and lower treble each sit about 1.3 dB under target, with a 4.8 dB dip near 6.3 kHz that slightly softens vocal articulation.

Tin HiFi T2 DLC: $39.00 Amazon eBay
Pros: Fifteen hobbyist measurements on squig.link put it at a preference score of 80.4 with a neutral overall tilt. Upper mids sit within 0.1 dB of target and low mids within half a decibel, so voices and guitars come through clean and natural. Treble peaks are gentle, topping out at just 1.4 dB, which keeps it easy on the ears.
Cons: Sub-bass runs about 2.3 dB below target and 2.7 dB down at 30 Hz, so the deepest bass notes lack weight. A sharp 7.7 dB dip near 10.6 kHz removes some cymbal shimmer and air.
