Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | FiiO - FH19 | Truthear - Nova |
|---|---|---|
| Sensitivity | 112 dB | 123 dB |
| Driver count | 10 | 5 |
| Impedance | 12 Ω | 15 Ω |
Between the FH19 and Nova, the FH19 comes out ahead in driver count / impedance, while the Nova wins on sensitivity. Overall, the FH19 scores 72.9 and the Nova scores 73.9 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (72.9 vs 73.9). The decision is not about overall quality — both clear the bar — it is about which specific trade-offs fit your use.
Pick the FH19 if you care most about driver count / impedance. The biggest gaps in its favor are driver count, impedance. The single most decisive one: Driver count — 5.00 more. 10 vs 5.
Pick the Nova if you care most about sensitivity. Its strongest claims are sensitivity. The single most decisive one: Sensitivity — 9.82% more. 123 dB vs 112 dB.
Both ship with comparable detachable cable, so those specs do not separate the two — focus on the differences below.
Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity says both are well-rounded; the differences are about trade-offs, not quality.
Which should you buy: FiiO - FH19 or Truthear - Nova?
Truthear - Nova leads the current Mars Score by 1.0 points.The more useful decision is the trade-off behind that result: compare driver count, impedance, sensitivity against the way you will actually use the product.
