Anker Soundcore Liberty 4 NC Earbuds Review (2026)

Why you should trust this review

I cover audio and electronics at The Tested Hub, and earbuds are a category where a quick listen tells you almost nothing about how a pair will hold up. I bought these Liberty 4 NC myself and Anker did not provide a sample, so there was no loaner to flatter. They went into my ears for real, on trains, at the gym, and at my desk, day in and day out.

Seven months is long enough to learn the things a launch review misses: whether the ANC still impresses once the novelty wears off, whether the battery holds up, and whether the fit stays comfortable over long sessions. I used them the way most people will, as daily commute and workout buds, and I kept the premium AirPods style alternatives in mind the whole time as the benchmark these are trying to undercut.

How we evaluated

My earbud routine is built around the things that actually matter day to day: noise cancellation on real commute noise, battery life against the rated figure, sound quality across genres, comfort over long wear, and how the app and controls hold up. I judged the ANC specifically on low frequency cabin and engine rumble, since that is the dominant noise on a commute and the thing budget ANC usually fails at.

For sound I listened across a range of material to check whether the bass stayed controlled or muddied the mids, and I used LDAC on an Android phone with higher bitrate files to see whether the hi res codec made an audible difference. I tracked real battery life across charge cycles, wore them for multi hour stretches to judge comfort and seal, and spent enough time in the Soundcore app to fairly assess its learning curve.

ANC: adaptive and genuinely effective

The adaptive ANC is the headline, and it earns its billing. It reads the ear seal and ambient noise automatically and clears the great majority of low frequency cabin rumble, the drone of a train carriage or a bus engine that makes a commute tiring. That is the hardest noise for budget ANC to handle, and these do it well enough that I stopped thinking about it, which is the real test. The adaptive part means I never had to fiddle with modes as I moved between environments.

The honest framing is that this is excellent ANC for the price, not flagship silence. Against the absolute best premium buds you can still find a small gap in the very last bit of cancellation and in how it handles higher frequency chatter. But the gap is far smaller than the price difference, and for the everyday job of taming a commute, the Liberty 4 NC punches well above where they sit on price.

Sound quality: punchy bass that stays clean

The 11mm dual driver is the second reason to like these. The bass is punchy and present, the kind of low end that makes pop, hip hop, and electronic music satisfying, but crucially it does not smear into the mids. A lot of budget buds chase a big bass impression and end up muddying vocals and instruments in the process. These keep the mids clear underneath the bass, which makes them enjoyable across far more genres than a typical bass forward budget pair.

LDAC support is the bonus that matters for Android owners. Paired with an Android phone and higher bitrate files, the hi res codec adds a bit more detail and air up top compared to the standard codecs. It is a subtle improvement rather than a night and day one, and iPhone users will not get it since iPhone does not support LDAC, but for Android listeners it is a genuine edge at this price that the premium AAC only alternatives simply cannot match.

Battery life: 50 hours that lasts

Battery is where these quietly crush the premium competition. The buds get around 10 hours on their own and 50 hours total with the case, which is a clear margin over the typical premium pair. In practice that meant I charged the case roughly once a week on normal commute use, and I almost never found myself caught out with dead buds. For anyone who hates battery anxiety, this alone is a strong reason to buy.

Over seven months the battery held up well, with no obvious collapse in runtime that you sometimes see as cheap cells age. The buds also charge over USB-C and support Qi wireless, so topping up the case is flexible. Long battery life on paper is easy to print, but these delivered it consistently across months of real use, which is what counts.

Comfort, build, and the app learning curve

Comfort over long sessions was good. The fit stayed secure through workouts thanks to the IPX4 sweat resistance, and they did not fatigue my ears over multi hour listening, which is not a given with in ear buds. The build feels solid for the price, and Bluetooth 5.3 with multipoint meant switching between my phone and laptop was painless once set up.

The honest gripes are minor. The case is bulkier than the slimmest premium cases, so it makes more of a bump in a pocket, and there is no Apple chip integration, so iPhone users miss the instant pairing and seamless device handoff that the Apple branded buds offer. The Soundcore app also takes a couple of sessions to learn, since it packs in a lot of EQ and ANC options that are not all obvious at first. None of these are dealbreakers, but they are the rough edges worth knowing.

Who should buy the Anker Soundcore Liberty 4 NC?

Buy them if you are an Android owner who wants LDAC and strong ANC without paying flagship money, or a budget conscious iPhone user who can live without the deep Apple integration. They are the right pick if you want excellent battery life, clean punchy sound, and effective commute ANC at a fraction of the premium price. For most people shopping in this tier, these are the smart buy.

Skip them if you are deep in the Apple ecosystem and value the seamless chip features and instant pairing enough to pay for them. Skip them too if you want the slimmest possible case or the absolute last word in ANC, where the premium options still hold a small lead. For everyone else, the value here is hard to argue with.

The verdict

The Anker Soundcore Liberty 4 NC are the budget ANC earbuds I keep recommending because they get the important things right. The adaptive ANC tames a commute, the dual driver delivers punchy bass that does not muddy the mids, LDAC gives Android users a real codec edge, and the 50 hour battery outlasts the premium competition by a clear margin. The bulkier case, the lack of Apple integration, and an app with a learning curve are easy trades at this price. If you want most of the flagship experience for roughly half the money, these are the ones to buy.
