Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | 64 Audio - U12t | Truthear - Nova |
|---|---|---|
| Driver count | 12 | 5 |
| Sensitivity | 115 dB | 123 dB |
| Impedance | 12 Ω | 15 Ω |
Between the U12t and Nova, the U12t comes out ahead in driver count / impedance, while the Nova wins on sensitivity. Overall, the U12t scores 79.3 and the Nova scores 73.9 on our Mars Score.
Which should you buy?
The U12t edges ahead on the Mars Score (79.3 vs 73.9), but the 5.4-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the U12t 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 — 7.00 more. 12 vs 5.
Pick the Nova if you care most about sensitivity. Its strongest claims are sensitivity. The single most decisive one: Sensitivity — 6.96% more. 123 dB vs 115 dB.
Both ship with comparable detachable cable, so those specs do not separate the two — focus on the differences below.
Bottom line: the U12t is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
Which should you buy: 64 Audio - U12t or Truthear - Nova?
64 Audio - U12t leads the current Mars Score by 5.4 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.
