↑↓ = difference vs the ★ model; lighter, longer battery and wider response are shown in green. “—” means the maker does not publish that figure.
Soundcore Liberty 4 NC is Soundcore’s true-wireless earbuds, released in 2023 at $99. The spec sheet lists dynamic、11 mm、5.6 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 true-wireless earbuds shelf its price ranks 37th (45 models with a price), and 1th most expensive of the 9 models in the $0–100 band. At 5.6 g it ranks 25th lightest of the 40 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 10/50 hours including the charging case. 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 5.6 g it is average 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 Nothing Ear (a), Samsung Galaxy Buds FE and Skullcandy Rail ANC. Nothing Ear (a) ($99 (same price))：4.8 g、42 hours battery；Samsung Galaxy Buds FE ($99 (same price))：5 g、21 hours battery；Skullcandy Rail ANC ($99 (same price))：4.5 g、32 hours battery。
5. Weaknesses worth stating
- Price position: of the 9 models in the $0–100 band, 0 cost more and 5 cost less.
6. What to buy instead at the same price
- The direct rivals are the three models from section 4 (Nothing Ear (a)、Samsung Galaxy Buds FE、Skullcandy Rail ANC) — which to pick depends on the spec you care about.
- Other checkable models in the $0–100 band: Nothing Ear (a)（$99、4.8 g）、Samsung Galaxy Buds FE（$99、5 g）、Skullcandy Rail ANC（$99、4.5 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.
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 No unmeasured listening impressions are included; unpublished figures show as “—” in the table.
