Between the Aria 2 and Nova, the Aria 2 comes out ahead in several specs, while the Nova wins on impedance and driver count. Overall, the Aria 2 scores 65.4 and the Nova scores 73.9 on our Mars Score.
Which should you buy?
The Nova is the clear pick on raw spec strength, leading by 8.5 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.
The Aria 2 doesn't 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 and driver count. Its strongest claims are impedance, driver count, sensitivity.
Both ship with comparable detachable cable, so those specs don't 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.
