Short answer: the Tin HiFi C2 Mech Warrior. It ranks #55 of 450 in-ear headphones by sound quality, rated 4.6/5, at $39; the Tin HiFi C2 2025 ranks #86, rated 4.5/5, at $39. With prices this close, go by the sound-quality ranking rather than the cost.
What the Tin HiFi C2 Mech Warrior does well: 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. The catch: 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.
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. The catch: A 7.7 dB peak near 11.9 kHz can add a hint of tizz to cymbals and hi-hats.

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.

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.
