What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Soundcore’s Liberty 4 NC and Liberty 4 Pro are plausible noise-cancelling earbud alternatives, but neither can be called a proven one-for-one replacement for an “EarFun Pro X”: EarFun’s official listings reviewed for this comparison do not identify a product by that name. Confirm whether you mean the in-ear EarFun Air Pro 4+ or the over-ear EarFun Wave Pro X before comparing fit, performance, or price.
First, check which EarFun product you mean
“EarFun Pro X” does not resolve to a specific model in the official EarFun product listings available for this comparison. That matters because the similarly named products are different types of headphones. EarFun’s September 5, 2025 announcement describes the Air Pro 4+ as adaptive hybrid ANC earbuds and the Wave Pro X as an over-ear headphone. Those are not interchangeable comparison targets.
- If you mean earbuds: the Air Pro 4+ is a possible intended model, but the available announcement does not establish a full comparison with either Soundcore option below.
- If you mean over-ear headphones: the Wave Pro X is the relevant type, and the Liberty 4 NC and Liberty 4 Pro are not direct alternatives because they are true-wireless earbuds.
Until the model is confirmed, treat the Soundcore products as ANC earbud options to investigate, not verified replacements for a particular EarFun product.
Soundcore options at a glance
| Model | What the manufacturer lists | What that means for a buyer |
|---|---|---|
| Soundcore Liberty 4 NC | True-wireless ANC earbuds with Adaptive ANC 2.0. Soundcore claims up to 98.5% noise reduction; this is a manufacturer product-page claim, not an independent measurement or comparison. A current price is not established here. | A candidate to consider if you want ANC earbuds and are prioritizing value. Check the current price in your market before deciding whether it is good value. |
| Soundcore Liberty 4 Pro | The US product page listed $149.99 when accessed on October 4, 2026. It lists Adaptive ANC 3.0, multipoint, IPX5, dual drivers, and up to 10 hours per charge or 40 hours with the case. These are manufacturer-listed specifications; actual battery life depends on use. | A more feature-rich option on paper. The listed US price is time-sensitive and does not establish that it is better value than the Liberty 4 NC or an EarFun model. |
How to choose between them
Choose by current local price, not the ANC version number
Soundcore’s Adaptive ANC 2.0 and 3.0 labels distinguish its product descriptions, but they do not provide a controlled, independent head-to-head result. The Liberty 4 NC’s up-to-98.5% figure is also a manufacturer claim, not evidence that it blocks more noise than an EarFun model or the Liberty 4 Pro. Compare current prices from sellers in your country, including any sale price, before judging value. The available evidence does not establish a current Liberty 4 NC price or a price for the intended EarFun model.

Match features to the way you listen
The Liberty 4 Pro’s manufacturer-listed multipoint may matter if you regularly switch between devices, while its IPX5 rating is a stated durability specification. Its listed battery figures are up to 10 hours per charge and 40 hours with the case; those figures are not a guarantee of runtime under every listening setup. The available product information does not establish comparable figures for the intended EarFun model, so do not assume the Soundcore has longer battery life or more useful features overall.
Fit and seal are personal
Earbud fit affects comfort and how well passive isolation works, which can influence the listening experience with ANC. No fit testing or independent comparison is established here. If possible, check the seller’s return policy and try the earbuds with the supplied tips before committing; a poor seal can make even a feature-rich ANC model a bad choice for you.

What to verify before buying
- Identify the EarFun model. Check the product name and whether it is an earbud or over-ear headphone. Do not compare Liberty earbuds against the Wave Pro X as though they share a form factor.
- Check your local, current price. The Liberty 4 Pro’s $149.99 figure is a US manufacturer-page listing accessed October 4, 2026, not a guaranteed transaction price. No current Liberty 4 NC or intended EarFun price is established here.
- Confirm the features you need. Verify battery conditions, device compatibility, multipoint, water-resistance rating, warranty, and return terms on the exact model and seller page in your market. The available information does not establish all of these points for a direct EarFun comparison.
- Use performance claims cautiously. A manufacturer’s ANC percentage or generation label is not an independent test. No cited independent head-to-head ANC result establishes which candidate cancels more noise.
Which one is the value pick?
There is not enough comparable pricing or independent ANC evidence to name a value winner. The Liberty 4 NC is a reasonable product to price-check if you are shopping for ANC earbuds; the Liberty 4 Pro is the more feature-rich cited option, with its US listing at $149.99 on October 4, 2026. Which makes more sense depends on their live prices where you shop, the features you will use, and whether you meant EarFun earbuds or an over-ear headphone in the first place.
