Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | FiiO - FH19 | Moondrop - Blessing 3 |
|---|---|---|
| Driver count | 10 | 5 |
| Sensitivity | 112 dB | 117 dB |
| Impedance | 12 Ω | 15 Ω |
Between the FH19 and Blessing 3, the FH19 comes out ahead in driver count / impedance, while the Blessing 3 wins on sensitivity. Overall, the FH19 scores 72.9 and the Blessing 3 scores 68.3 on our Mars Score.
Which should you buy?
The FH19 edges ahead on the Mars Score (72.9 vs 68.3), but the 4.6-point gap is small enough that the right pick comes down to which spec advantages matter to you.
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 Blessing 3 if you care most about sensitivity. Its strongest claims are sensitivity. The single most decisive one: Sensitivity — 4.46% more. 117 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 Moondrop - Blessing 3?
FiiO - FH19 leads the current Mars Score by 4.6 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.
