The Soundcore Liberty 4 NC has become something of a legend in the budget earbud space. At $60–100 depending on when you catch them, reviewers are throwing around comparisons to AirPods Pro and $300–400 premium earbuds. That's a bold claim. After combing through months of real-world user experiences, here's the honest picture.

The Case For These Being Genuinely Special

The noise cancellation is the headline feature — and it mostly delivers. One reviewer who tested side-by-side against the EarFun Air Pro 4 in a noisy cafe called the Liberty 4 NC "noticeably superior." Another was so impressed that when ANC was active with music playing, all they could see was people's lips moving. A JBL loyalist who had spent up to $180 on earbuds described it as a "game changer" — and then immediately ordered a backup pair in white.

Someone who bought these as an AirPods Pro backup ended up replacing them entirely. Their verdict: in everyday use, it's hard to tell the difference — except the battery lasts noticeably longer and the price is a fraction of Apple's ask.

The battery life borders on absurd. One user genuinely thought something was broken — the battery barely moved after 8 hours a day for three days straight. They contacted Soundcore support to troubleshoot. Turns out it was just... working as advertised. That's the kind of battery performance that makes long flights and all-day wear a non-issue.

The app is a genuine differentiator at this price. It runs a personalized hearing test and an A/B comparison sequence to dial in your ideal EQ curve — something you'd expect from much more expensive gear. Touch controls are fully customizable (single, double, triple tap, and hold on each bud), and critically, you can disable on-bud controls entirely if you keep adjusting them accidentally. Wind noise reduction with manual maximum ANC is strong enough that a cyclist described feeling the wind on their face but barely hearing it.

Sound Quality: Punching Well Above Its Weight

Multiple reviewers with direct comparisons — against JBL, EarFun, 1More, and P40i — consistently land on the Liberty 4 NC as the winner on sound. The 11mm drivers versus 8mm in the JBL Vibe Beam is one cited reason. Bass is described as thumping, vocals clear, with nuances that users hadn't heard in the same music through pricier earbuds.

One honest note: between songs or in silent passages, there is a faint white noise hiss. Reviewers who tested the P40i noted that competitor doesn't have this issue. For casual listeners it won't matter; for those who value silence between tracks, it's worth knowing.

The Fit Problem Is Real — And Polarizing

This is the most divided topic across all reviews. Some users wore them through weight training and 6-mile walks without a single adjustment. Others with smaller or differently shaped ears find them consistently problematic — slipping out, failing to seal, and causing ear fatigue after a few hours. One reviewer noted the earbuds feel noticeably heavy compared to lighter alternatives.

The stock silicone ear tips are a recurring complaint — multiple users say they don't stay attached to the earbuds reliably and that aftermarket tips are worth the investment. If you have small ears or have struggled with earbud fit historically, this is a real risk factor. The shape and angle of the housing doesn't work for everyone.

Multipoint Connectivity: A Known Weak Spot

After five months of daily use, one reviewer dropped the rating specifically because of multipoint behavior. It works cleanly about 60% of the time by their estimate. The specific failure modes: phone audio auto-prioritizes over computer playback unexpectedly, sound cuts out on the computer when a text arrives silently on the phone, and occasional multi-attempt reconnection battles. Bose owners will find this frustrating by comparison.

If you're only connecting to one device at a time, this is a non-issue. If seamless dual-device switching is important to your workflow, temper your expectations.

A Serious Warning: The Known Firmware Bug

This deserves its own section because it's significant. At least one buyer encountered a documented hardware-software interaction bug where ANC causes random bass drops and volume fluctuations. Soundcore support confirmed the issue, sent a replacement unit — which had the same problem — and then candidly admitted in writing that the root cause is a complex firmware-hardware interaction issue with no confirmed fix timeline, and offered a refund instead.

The good news: the support response was transparent and handled professionally. The bad news: this bug exists, affects multiple units, and has no confirmed patch date. Most reviewers have not reported this issue, so it may be limited to specific hardware batches or usage patterns (earbud insertion tightness and sudden ambient noise changes are cited as triggers). But if you buy these and notice erratic ANC behavior, know that you're not imagining it — and that a return is the cleanest path forward.

The Case and Build

Wireless charging works and is fast. The case is lightweight — perhaps too much so — with a hinge that has some play to it and a lid that opens very easily. Drop it and the earbuds will likely fly out. The button to open the lid is awkwardly positioned low on the case, requiring two hands or a fingernail for clean access. There's no lanyard loop and no official protective case, only poor-fitting third-party silicone options.

Buyer Tips Worth Knowing

• Download the Soundcore app first — the personalized EQ test alone is worth the five minutes
• For wind reduction while cycling or outdoors, use manual mode at maximum level 5 with wind reduction enabled
• If on-bud controls frustrate you, they can be fully disabled in the app
• Aftermarket ear tips are a worthwhile upgrade if the stock ones don't seal well for you
• Wireless charging pads that work with AirPods also work with these
• LDAC codec is supported — worth enabling for improved audio quality if your phone supports it

The Verdict

For most people — those with average ear shapes, primarily single-device users, and anyone prioritizing ANC and battery over flawless multipoint — the Liberty 4 NC is a genuinely exceptional value. The ANC outperforms earbuds at twice the price, the battery life is borderline ridiculous, and the app-driven personalization features belong on a $200 product. Multiple buyers have called these a replacement for their AirPods Pro, and that's not hyperbole from people who have used both side-by-side.

The caveats are real though. Fit is hit-or-miss depending on your ear anatomy. Multipoint is unreliable enough to matter if that's part of your daily workflow. And the known firmware bug — while not widespread — is severe enough that you should monitor your first week of use carefully and return without hesitation if you see erratic ANC behavior.

At the right price, this is one of the best purchases in the budget earbud category. Just go in with eyes open.

Frequently Asked Questions

Q: How does the Soundcore Liberty 4 NC compare to AirPods Pro?

A: Multiple users who own both say the Liberty 4 NC is competitive on ANC and sound quality in everyday use, with significantly better battery life. The main AirPods Pro advantages are Apple ecosystem integration (Find My, instant pairing, Siri) — if those features don't matter to you, the Liberty 4 NC delivers comparable core performance at a fraction of the price.

Q: What is the real-world battery life on the Soundcore Liberty 4 NC?

A: One user ran them at 8 hours per day for three days before the battery indicator moved noticeably. Rated at 50 hours total (buds plus case), real-world use confirms the battery life is exceptional — well beyond what most users will drain in a single week of daily listening.

Q: Is the multipoint Bluetooth connection reliable?

A: Mixed results after extended use. One long-term reviewer estimated it works correctly about 60% of the time, with issues including unexpected phone audio prioritization over computer playback. If you only connect to one device at a time, this isn't a concern. If seamless dual-device switching is important, consider competitors like Bose.

Q: Are there any known defects or firmware bugs?

A: Yes — Soundcore support confirmed a documented bug where ANC can cause random bass drops and volume fluctuations under specific usage conditions (earbud insertion tightness, sudden ambient noise changes). The company offered refunds while working on a fix, with no confirmed timeline for a firmware patch at time of writing. Most users have not reported this issue, but it's worth monitoring during your first week of use.

Q: Do the Liberty 4 NC earbuds work well for outdoor activities like cycling?

A: Yes, with the right settings. Using manual mode at maximum (level 5) ANC with wind reduction enabled, one regular cyclist reported feeling wind on their face but barely hearing it — a significant improvement over competing earbuds like the EarFun Air Pro 4 and 1More ComfoBuds Pro tested in the same conditions.
