The Soundcore Liberty 4 NC offers an unusually long feature list for a value-oriented earbud: adaptive noise cancellation, LDAC, app-based personalisation and multipoint. That combination explains why it remains worth researching alongside newer models. The challenge is deciding which features are useful together and which are marketing figures that need more context.
Research-based review. This assessment examines manufacturer documentation and the product’s suitability for different systems. We have not carried out hands-on listening, laboratory measurements or a battery test of this model. Performance figures below are manufacturer claims, not independently measured results.
Personalisation is a useful starting point
Soundcore provides HearID 2.0, a fully adjustable EQ and 22 presets. These offer several routes to a preferred balance, but more settings do not automatically mean better sound. Start with a consistent ear-tip fit and a moderate level before changing the response. Otherwise a poor seal may be mistaken for a tuning problem.
A sensible process is to save one modest adjustment, compare familiar music at matched volume, and keep an unmodified setting for reference. Avoid repeatedly raising bass or treble to compensate for a noisy environment. That may make the sound more immediately noticeable while doing little to improve long-session comfort.
Adaptive ANC needs realistic interpretation
The product page describes Adaptive ANC 2.0 and advertises noise reduction of up to 98.5 percent. A percentage without a shared test method does not allow a direct ranking against another manufacturer’s decibel claim or an independent frequency-by-frequency isolation measurement.
The useful fact is that the product offers active noise management intended to adjust to ears and surroundings. Whether it works well on your train, with your fit or in windy conditions remains a practical question. This review has not performed those tests, and does not turn the advertised percentage into a claim about every real-world noise.
LDAC and multipoint are source-dependent conveniences
The official page lists LDAC, Bluetooth 5.3 and multipoint. LDAC requires a compatible source; an iPhone will not use it simply because the earbuds support it. Confirm the available settings on the actual phone rather than paying for a codec badge that your main device cannot exploit.
For someone using a work laptop and phone, predictable switching may be more valuable than a higher-bitrate music mode. Check current app and firmware guidance for which features can operate together. A connection specification is not a guarantee of identical behaviour in every meeting application or operating system.
Battery planning and durability
Soundcore states up to 10 hours per charge and 50 hours with the case in normal mode. With ANC on, the stated figures are eight hours and 40 hours. Those figures describe different settings, so the larger total should not be used as an ANC-runtime promise.
IPX4 resistance is useful for light splashes, but it is not permission to swim with the earbuds or charge them while wet. Fit and retention also matter for workouts. For ownership value, check local warranty support, replacement tips and whether the case is easy to carry; these practical points may outweigh another sound preset in daily use.
What to expect in a real setup
Is the 50-hour claim for ANC listening? No. Soundcore lists 50 hours including the case in normal mode, and up to 40 hours with ANC. Real use depends on settings and conditions.
Will LDAC work with an iPhone? Not as a normal Bluetooth codec on an iPhone. Both the source and the earbuds must support LDAC for that transmission mode.
Alternatives to consider
Anker Soundcore Liberty 5: Compare the newer Soundcore option if the price difference is modest, focusing on changes you will actually use.
Nothing Ear (a): A relevant alternative for listeners comparing app controls, everyday ANC features and design rather than chasing a single specification.

Verdict

Buy for a practical combination of fit, ANC and controls, rather than treating the advertised reduction percentage as proof of superiority.
