Short answer: the DUNU Titan S2. It ranks #122 of 466 in-ear headphones by sound quality (rated 4.4/5); the DUNU Titan S ranks #284 (rated 3.9/5).
Why pick the DUNU Titan S: Crinacle’s measurement gives it a preference score of 73, and across 34 hobbyist measurements on squig.link the bass, low mids and upper mids all land within half a decibel of the Harman target. The catch: Hobbyist measurements put sub-bass about 3.2 dB below target, so the deepest synth and cinematic bass hits carry less rumble than the Harman curve calls for.
The DUNU Titan S2 is the better-sounding option.

Newer model: the DUNU Titan S2, ranked higher, rated 4.4/5, released Jun 2024. See every DUNU Titan S generation.
Pros: Crinacle’s measurement gives it a preference score of 73, and across 34 hobbyist measurements on squig.link the bass, low mids and upper mids all land within half a decibel of the Harman target. That keeps vocals, piano and guitars sounding natural rather than pushed forward or recessed. With a 32 ohm load and a 110 dB sensitivity rating, it plays at comfortable volume straight from a phone.
Cons: Hobbyist measurements put sub-bass about 3.2 dB below target, so the deepest synth and cinematic bass hits carry less rumble than the Harman curve calls for. A 4.9 dB dip near 6.1 kHz followed by a 4.1 dB peak near 11.9 kHz gives the treble an uneven texture, softening some detail while adding a touch of glare up top.
