Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Letshuoer - Cadenza 12 | Truthear - Nova |
|---|---|---|
| Sensitivity | 105 dB | 123 dB |
| Driver count | 12 | 5 |
| Impedance | 16 Ω | 15 Ω |
Between the Cadenza 12 and Nova, the Cadenza 12 comes out ahead in driver count, while the Nova wins on sensitivity / impedance. Overall, the Cadenza 12 scores 70.1 and the Nova scores 73.9 on our Mars Score.
Which should you buy?
The Nova edges ahead on the Mars Score (70.1 vs 73.9), but the 3.8-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the Cadenza 12 if you care most about driver count. The biggest gaps in its favor are driver count. The single most decisive one: Driver count — 7.00 more. 12 vs 5.
Pick the Nova if you care most about sensitivity / impedance. Its strongest claims are sensitivity, impedance. The single most decisive one: Sensitivity — 17.14% more. 123 dB vs 105 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: Letshuoer - Cadenza 12 or Truthear - Nova?
Truthear - Nova leads the current Mars Score by 3.8 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.
