Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | KZ - ZAR | Letshuoer - Cadenza 12 |
|---|---|---|
| Impedance | 26 Ω | 16 Ω |
| Driver count | 8 | 12 |
| Sensitivity | 108 dB | 105 dB |
Between the ZAR and Cadenza 12, the ZAR comes out ahead in sensitivity, while the Cadenza 12 wins on impedance / driver count. Overall, the ZAR scores 65.4 and the Cadenza 12 scores 70.1 on our Mars Score.
Which should you buy?
The Cadenza 12 edges ahead on the Mars Score (65.4 vs 70.1), but the 4.7-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the ZAR if you care most about sensitivity. The biggest gaps in its favor are sensitivity. The single most decisive one: Sensitivity — 2.86% more. 108 dB vs 105 dB.
Pick the Cadenza 12 if you care most about impedance / driver count. Its strongest claims are impedance, driver count. The single most decisive one: Impedance — 10.00 Ω less. 16 vs 26.
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: KZ - ZAR or Letshuoer - Cadenza 12?
Letshuoer - Cadenza 12 leads the current Mars Score by 4.7 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.
