↑↓ = difference vs the ★ model; lighter, longer battery and wider response are shown in green. “—” means the maker does not publish that figure.
Sony WH-ULT900N is Sony’s over-ear, released in 2024 at $199. The spec sheet lists dynamic、30 mm、255 g、50 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 70th (102 models with a price), and 1th most expensive of the 26 models in the $100–200 band. At 255 g it ranks 27th lightest of the 101 models with weight data. The maker publishes neither impedance nor sensitivity — common in this form factor, so we compare only the checkable fields.
2. What the numbers change in daily use
Bluetooth 5.2 with SBC,AAC,LDAC, with active noise cancelling. Rated battery is 30/50 hours（maker-rated）. 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 255 g it is on the light 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 AKG N700NC M2, JBL Live 770NC and Skullcandy Crusher ANC 2. AKG N700NC M2 ($199 (same price))：280 g、23 hours battery；JBL Live 770NC ($199 (same price))：267 g、80 hours battery；Skullcandy Crusher ANC 2 ($199 (same price))：322 g。
5. Weaknesses worth stating
- No water-resistance rating is published: sweaty workouts and rainy commutes are out.
- Price position: of the 26 models in the $100–200 band, 0 cost more and 18 cost less.
- Battery is not a strength: JBL Live 770NC（80 hours） all last longer than its 50 hours.
6. What to buy instead at the same price
- The direct rivals are the three models from section 4 (AKG N700NC M2、JBL Live 770NC、Skullcandy Crusher ANC 2) — which to pick depends on the spec you care about.
- Other checkable models in the $100–200 band: Audio-Technica ATH-M50xBT2（$199、38 Ω、99 dB、307 g）、AKG N700NC M2（$199、280 g）、JBL Live 770NC（$199、267 g）.
7. Who it is for — and who it is not
- Commuting and office: ANC plus 50 hours of battery.
- Android users: LDAC is its hard edge over same-price rivals.
- Sport or rain: no water-resistance rating is published.
- Long days out: the JBL Live 770NC lasts 80 hours.
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). No unmeasured listening impressions are included; unpublished figures show as “—” in the table.
