Audeze Maxwell is Audeze’s over-ear, released in 2023 at $299. The spec sheet lists planar-magnetic、90 mm、28 Ω、95 dB、490 g、80 hours。Its value is not one dramatic number but where those specs land at this price.
1. Where it sits on the shelf
On this over-ear shelf its price ranks 56th (102 models with a price), and 3th most expensive of the 16 models in the $200–300 band. At 490 g it ranks 96th lightest of the 101 models with weight data. 28 Ω ranks 51th highest of the 62 models that publish impedance. 95 dB ranks 57th lowest of the 68 models that publish sensitivity.
2. What the numbers change in daily use
Bluetooth 5.3 with SBC,AAC,LDAC,aptX HD, with active noise cancelling. Rated battery is 80 hours. On LDAC-capable Android devices a high-resolution path around 990 kbps is available, while an iPhone falls back to AAC.At 2 hours of commuting a day that is roughly one charge every two weeks.
3. Fit, isolation and use cases
At 490 g it is on the heavy side for this form factor. It has active noise cancelling, which handles commute noise. 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 Shure AONIC 50 Gen 2, Sony INZONE H9 and JBL Tour One M3. Shure AONIC 50 Gen 2 ($299 (same price))：334 g、44 Ω、97 dB、45 hours battery；Sony INZONE H9 ($299 (same price))：330 g、32 hours battery；JBL Tour One M3 ($329 ($30$ less))：288 g、65 hours battery。
5. Weaknesses worth stating
- No water-resistance rating is published: sweaty workouts and rainy commutes are out.
- Price position: of the 16 models in the $200–300 band, 0 cost more and 10 cost less.
6. What to buy instead at the same price
- The direct rivals are the three models from section 4 (Shure AONIC 50 Gen 2、Sony INZONE H9、JBL Tour One M3) — which to pick depends on the spec you care about.
- Other checkable models in the $200–300 band: FiiO FT3（$299、350 Ω、105 dB、430 g）、HiFiMAN Sundara（$299、94 dB、372 g）、Shure AONIC 50 Gen 2（$299、44 Ω、97 dB、334 g）.
7. Who it is for — and who it is not
- Commuting and office: ANC plus 80 hours of battery.
- Android users: LDAC is its hard edge over same-price rivals.
- Sport or rain: no water-resistance rating is published.
Data note: every claim comes from maker-published specs in our own product database and same-price comparisons (price, weight, impedance, sensitivity, frequency response, codecs and battery are checkable fields).
