Moondrop Aria 2 is Moondrop’s wired in-ear, released in 2024 at $79. The spec sheet lists dynamic、10 mm、20 Ω、108 dB、5 g。Its value is not one dramatic number but where those specs land at this price.
1. Where it sits on the shelf
On this wired in-ear shelf its price ranks 38th (57 models with a price), and 4th most expensive of the 23 models in the $0–100 band. At 5 g it ranks 8th lightest of the 57 models with weight data. 20 Ω ranks 22th highest of the 57 models that publish impedance. 108 dB ranks 33th lowest of the 57 models that publish sensitivity.
2. What the numbers change in daily use
At 20 Ω and 108 dB sensitivity. Ordinary gear can drive it; no dedicated amp is required.
The rated frequency response reaches 40 kHz.
3. Fit, isolation and use cases
At 5 g it is on the light side for this form factor. In-ear tips give passive isolation, enough for commuting. No water-resistance rating is published, so sport and rain are out.
4. Head to head with its three closest rivals
The three closest rivals at this price are the Truthear Hexa, 7Hz Legato and KZ PR2. Truthear Hexa ($79 (same price))：7.3 g、21 Ω、110 dB；7Hz Legato ($79 (same price))：7.4 g、16 Ω、108 dB；KZ PR2 ($79 (same price))：8 g、24 Ω、102 dB。
5. Weaknesses worth stating
- No water-resistance rating is published: sweaty workouts and rainy commutes are out.
- Price position: of the 23 models in the $0–100 band, 2 cost more and 16 cost less.
6. What to buy instead at the same price
- The direct rivals are the three models from section 4 (Truthear Hexa、7Hz Legato、KZ PR2) — which to pick depends on the spec you care about.
- Other checkable models in the $0–100 band: Truthear Hexa（$79、21 Ω、110 dB、7.3 g）、7Hz Legato（$79、16 Ω、108 dB、7.4 g）、KZ PR2（$79、24 Ω、102 dB、8 g）.
7. Who it is for — and who it is not
- Long sessions: 5 g is on the light side for this form factor.
- Sport or rain: no water-resistance rating is published.
- Wireless-only listeners: this is a wired model needing a front end and a cable.
