Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | FiiO - FH19 | Letshuoer - Cadenza 12 |
|---|---|---|
| Sensitivity | 112 dB | 105 dB |
| Impedance | 12 Ω | 16 Ω |
| Driver count | 10 | 12 |
Between the FH19 and Cadenza 12, the FH19 comes out ahead in sensitivity / impedance, while the Cadenza 12 wins on driver count. Overall, the FH19 scores 72.9 and the Cadenza 12 scores 70.1 on our Mars Score.
Which should you buy?
These two are nearly even on the Mars Score (72.9 vs 70.1). 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 sensitivity / impedance. The biggest gaps in its favor are sensitivity, impedance. The single most decisive one: Sensitivity — 6.67% more. 112 dB vs 105 dB.
Pick the Cadenza 12 if you care most about driver count. Its strongest claims are driver count. The single most decisive one: Driver count — 2.00 more. 12 vs 10.
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 Letshuoer - Cadenza 12?
FiiO - FH19 leads the current Mars Score by 2.8 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.
