Where they actually differ
The most decisive specs, ranked by how much they matter — before the full spec table.
| Spec | Shure - AONIC 5 | Truthear - Nova |
|---|---|---|
| Impedance | 36 Ω | 15 Ω |
| Sensitivity | 119 dB | 123 dB |
| Driver count | 3 | 5 |
Between the AONIC 5 and Nova, the AONIC 5 comes out ahead in several specs, while the Nova wins on impedance / sensitivity. Overall, the AONIC 5 scores 66.4 and the Nova scores 73.9 on our Mars Score.
Which should you buy?
The Nova edges ahead on the Mars Score (66.4 vs 73.9), but the 7.5-point gap is small enough that the right pick comes down to which spec advantages matter to you.
The AONIC 5 does not pull ahead on any single popular-comparison spec — its strengths sit in the spec-table groups rather than the headline advantages.
Pick the Nova if you care most about impedance / sensitivity. Its strongest claims are impedance, sensitivity, driver count. The single most decisive one: Impedance — 21.00 Ω less. 15 vs 36.
Both ship with comparable detachable cable, so those specs do not separate the two — focus on the differences below.
Bottom line: the Nova 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: Shure - AONIC 5 or Truthear - Nova?
Truthear - Nova leads the current Mars Score by 7.5 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.
Choose Shure - AONIC 5 if…
Shure - AONIC 5 does not lead a decisive measured field here, so choose it for price, ecosystem, design, or availability when those matter more to you.
Choose Truthear - Nova if…
Truthear - Nova has the measurable edge on impedance ohm, sensitivity db, driver count.
This is a structured comparison of the published catalog values. It is not a claim of identical real-world performance across every workload; use the linked spec drill-downs and methodology page to inspect the inputs.
