Soundcore Liberty 4 NC Review: Are the ANC Claims Actually True?

My Subway Platform Is My ANC Torture Test

My subway platform has a bus idling on the street above it every single morning, and that low diesel rumble is my personal torture test for any noise-cancelling earbud. When I put the Soundcore Liberty 4 NC in for the first time and walked onto that platform, I braced for the usual half-measure hiss. What I actually got surprised me — and, three weeks later, so did a few of the earbuds' rougher edges.

This Soundcore Liberty 4 NC review covers everything from daily fit to LDAC sound quality, ANC performance against Anker's bold 98.5% noise-reduction claim, and how these compare to other budget picks I've tested. If you're deciding between these and something like the best alternatives to the Galaxy Buds FE, I'll walk through exactly where the Liberty 4 NC earns its $99 price tag — and where it doesn't.

⚡ Top Pick Summary

🔬 My Testing Setup

Before getting into results, here's exactly how I tested these over a 21-day period, since "I tested them for three weeks" doesn't mean much without specifics:

📊 Category Test Scores

👂 Design and Comfort After Three Weeks of Daily Wear

The Liberty 4 NC uses a compact in-ear shape with a short stem, and it sits noticeably lighter than Soundcore's older Life P3. During my first gym session, I noticed the left bud shifting slightly during burpees. A firmer eartip swap fixed most of it, but out of the box, fit consistency was hit or miss. If you have smaller ear canals, budget a few minutes to cycle through the included tip sizes before judging comfort.

Weight-wise, each bud comes in under half an ounce, so all-day wear didn't cause the ear fatigue I've felt with bulkier over-ear alternatives like the JBL Tune 230NC vs Soundcore Life P3 comparison I ran earlier this year. The charging case, however, felt less durable than I expected — the hinge has some give that made me nervous tossing it loose in a gym bag.

🎵 Sound Quality and LDAC Performance

This is where my music production background actually mattered. I A/B tested the Liberty 4 NC against a reference pair using a mix of tracks: dense low-end hip-hop, an acoustic folk session, and an orchestral recording with wide dynamic range. With LDAC enabled on an Android phone, the 11mm drivers delivered noticeably more separation in the low-mids than I expected from a $99 earbud. Bass hits with punch rather than mud, and vocals stay forward instead of getting buried.

Switching to SBC on an iPhone (LDAC is Android-only) closed some of that gap, and the soundstage felt slightly flatter. It's still a solid listen for iPhone owners, just not the full-fidelity experience Android users get. If you're shopping specifically as an iPhone owner, my roundup of the best earbuds for iPhone under $100 covers a few picks tuned better for that scenario.

The Soundcore app's HearID 2.0 profile also nudged clarity higher once I ran the hearing test, which takes about two minutes and genuinely changed how upper mids came through on vocal-heavy tracks.

🔇 Active Noise Cancellation — Real-World Test

Anker rates Adaptive ANC 2.0 at up to 98.5% noise reduction. On paper, that's an aggressive number. In practice, it handled steady low-frequency drone — my subway platform's bus idle, HVAC hum, airplane cabin noise — quite well. However, it struggled more with sudden or higher-frequency sounds: wind gusts during an outdoor walk cut through noticeably, and nearby conversation wasn't fully suppressed.

Transparency mode, by contrast, impressed me. Ambient sound came through clearly and without the tinny artificial quality some budget ANC earbuds add. If your main use case is blocking out consistent background noise rather than unpredictable environments, the ANC here does its job. If you need it for a windy commute or an open office with constant chatter, temper your expectations below the marketing claim.

🎙️ Call Quality and Microphone Performance

I ran six separate calls across Zoom, a regular phone call, and a Discord voice chat — indoors, outdoors, and once next to a running dishwasher. Indoor call clarity was genuinely good; my voice came through clean with minimal background bleed. Outdoors was a different story. Wind noise cut into the mic pickup more than I'd like on a review earbud, and the person on the other end mentioned some crackling during a moderately breezy walk.

For anyone whose primary use case is calls, it's worth comparing against dedicated mic-first picks. I cover several stronger options in my guide to earbuds with the best mic quality for calls.

🔋 Battery Life — What I Actually Got

Soundcore's official numbers, confirmed on their support documentation, break down by mode: 10 hours in normal mode, 8 hours with ANC on, and roughly 5 hours with both ANC and LDAC running simultaneously. My real-world testing landed close to these figures — I averaged about 7.5 hours with ANC on at moderate volume, slightly under the rated 8, which is a reasonable and expected gap between lab conditions and daily use.

The case adds meaningful backup, topping out near 40–50 hours total depending on mode, and a 10-minute quick charge is enough for roughly 4 hours of playback — handy on a rushed morning. Just don't expect LDAC and ANC together to stretch much past a workday.

On rated numbers alone, the Liberty 4 NC leads this group on both single-charge and total case battery life with ANC engaged — a real edge if all-day case backup matters to you.

📱 Soundcore App, EQ Presets, and HearID 2.0

The Soundcore app remains one of the more generous companion apps in this price range. You get 22 EQ presets plus a fully adjustable custom EQ, along with the HearID 2.0 hearing test that tailors frequency response to your ears specifically. As someone who spends a lot of time adjusting EQ curves professionally, I appreciated having granular sliders rather than a locked three-band setup.

ANC intensity, transparency tuning, and touch-control remapping all live in the same app, and firmware updates have been reasonably frequent since launch — worth checking on first setup, since an outdated firmware version noticeably affected my early ANC results.

🔗 Bluetooth 5.3 and Multipoint Connectivity

Bluetooth 5.3 with multipoint pairing let me stay connected to my laptop for a call while my phone queued up notifications, and switching between the two was mostly seamless. I did hit a couple of dropouts during testing — nothing that ruined a call, but enough hiccups over three weeks that I'd call connectivity "mostly reliable" rather than flawless.

If multipoint is a dealbreaker feature for your workflow, I'd also point you toward my dedicated roundup of earbuds with multipoint connection for a few more options to weigh against this one.

⚖️ Soundcore Liberty 4 NC vs Sony WF-C700N

Soundcore Liberty 4 NC vs Sony WF-C700N is one of the most common comparisons buyers search before choosing between these two budget ANC options. In short: the Liberty 4 NC wins on driver quality, LDAC support, and app customization, while the Sony pick edges ahead on ANC consistency in windy or unpredictable environments. I've laid out the full breakdown, including call quality and battery testing side by side, in my dedicated Soundcore Liberty 4 NC vs Sony WF-C700N comparison.

Is the Soundcore Liberty 4 NC Good for Calls?

Indoors, yes — voice clarity was one of the stronger points in my testing, with minimal echo or muffling on standard phone calls and Zoom. Outdoors in wind, performance drops noticeably, and that's the main caveat I'd flag to anyone using these primarily for outdoor work calls. If calls are your top priority over gym use or commuting, weigh that outdoor mic weakness carefully before buying.

A Budget AirPods Alternative Under $100?

For iPhone owners specifically hunting for a Soundcore Liberty 4 NC vs AirPods alternative under $100, the honest answer is: it depends on priorities. You lose LDAC on iOS and touch controls feel slightly less polished than AirPods, but you gain a fully adjustable EQ, stronger bass presence, and a lower price than even the most basic AirPods model. It's a reasonable swap if sound customization matters more to you than ecosystem integration.

✅ Pros & Cons

🎯 Who Should Buy the Soundcore Liberty 4 NC

Buy these if you care more about detailed, LDAC-capable sound and a customizable EQ than about class-leading ANC. Skip them if your main use case is blocking out unpredictable outdoor noise or if you make frequent windy outdoor calls — the ANC and mic performance won't fully match Anker's marketing claims in those specific scenarios.

Skip These Earbuds If...

• You mainly use an iPhone: you lose LDAC entirely, which is a big part of what makes this earbud stand out
• ANC is your highest priority: the Sony WF-C700N held up more consistently against wind and chatter in my testing
• You work outdoors frequently: mic performance in wind was the weakest part of my three-week test
• You need the strongest microphones on the market: indoor calls are good, but dedicated mic-first picks will outperform this outdoors
