Short answer: both are discontinued, so this only matters if you are buying used. Used, the Final Audio Heaven V is the better pick: it ranks #871 of 1253 in-ear headphones by sound quality (rated 3.4/5), against #1249 (rated 1.0/5) for the Final Audio Heaven III. If you want one new, the Truthear Nova ranks #2 at $169.99.
The Final Audio Heaven V is the better-sounding choice. Lower mids sit within about 0.5 dB of target, keeping voices and guitars natural. The catch: Discontinued, so it is mainly found used.
Why pick the Final Audio Heaven III: A published AutoEQ preset corrects its response toward the Harman target, so a few minutes of EQ setup closes most of the gap. The catch: Measures far from the Harman target (preference score 17), so most listeners will hear it as colored; EQ can correct much of this.
Buy the Final Audio Heaven V only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Truthear Nova instead.
