The 30-Second Version

The Soundcore Liberty 4 NC are true wireless noise cancelling earbuds that deliver flagship-level ANC and a monstrous 50-hour battery at a budget price. They sound great with a little EQ tweaking and handle calls like a champ. Just don't expect them to stay put during burpees.

Overview

If you've been hunting for wireless earbuds that punch way above their price tag in noise cancelling, the Soundcore Liberty 4 NC should be right near the top of your list. These true wireless in-ears pack adaptive ANC, LDAC support, and an absurd 50-hour total battery life into a sub-$100 package that honestly embarrasses some flagships. Soundcore's trick is that 98.5% noise reduction claim—and while that number might sound like marketing fluff, in our testing it lands in the 97th percentile for ANC, which means these things hush the outside world better than almost anything else we've measured.

They're built around an 11mm dynamic driver, Bluetooth 5.3 with multipoint, and a six-mic setup that handles calls surprisingly well. IPX4 water resistance means they'll survive a sweaty commute or a drizzle, though we wouldn't take them on a run if fitness is your main jam. For travel, office work, or just drowning out chatty seatmates, the Liberty 4 NC delivers a feature set that makes you wonder why anyone would spend twice as much.

A quick look at the customer pulse tells the same story—over 99,000 reviews and a 4.3 average on Amazon suggests people are seriously happy. The main gripes? Comfort can be hit-or-miss after long sessions, and they're not the most gym-friendly buds. But if your priority is silencing the world without draining your wallet, these are tough to beat.

Performance

For earbuds that often dip as low as $53 across vendors, the Liberty 4 NC posts numbers that belong in a higher tax bracket. Active noise cancelling sits in the 97th percentile of our database—it's one of the absolute best right now, easily rivaling over-ear models for steady-state hums like airplane engines or HVAC drone. The adaptive ANC 2.0 adjusts in real-time, and while you can hear a faint hiss in complete silence, the actual reduction is deep and effective. Mic quality also hits the 97th percentile, making phone calls crisp and almost entirely free of background chatter thanks to those six beamforming mics and AI noise suppression.

Sound quality lands in the 88th percentile—so it's strong, if not quite flagship-tier. The 11mm drivers deliver a v-shaped profile with punchy bass and clear highs, but out of the box the upper mids can feel a little recessed. Turning on LDAC and fiddling with the HearID 2.0 EQ (or one of the 22 presets) tightens things up considerably. Battery life is a standout: 10 hours from the buds alone and another 40 in the case gets you to 50 hours total, which sits in the 94th percentile. A quick 10-minute charge nets 4 hours of playback, so battery anxiety doesn't really exist here.

The Word on the Street

4.3/5 (99553 reviews)
👍 Buyers consistently rave about the jaw-dropping noise cancellation and battery life, often calling them the best value in wireless earbuds.
👎 A recurring complaint is the fit—many find they loosen during movement and cause fatigue after a couple of hours of wear.
🤔 Sound quality opinions are split: some love the punchy out-of-box tuning, while others say the bass-heavy profile needs EQ to shine.

Value & Pricing

Price is a bit of a moving target with these—we've seen them anywhere from $53 to $469 depending on the vendor, which is wild. The best deal right now tends to be on Amazon, where they often hover around $70 to $100. At that level, you're getting flagship-grade ANC and battery life for the price of a pair of generic buds. The closest alternatives like the EarFun Air Pro 4+ or the Samsung Galaxy Buds3 Pro either cost more or compromise on noise cancelling. If pure value is your metric, the Liberty 4 NC is a no-brainer.

vs Competition

Stacked against the Samsung Galaxy Buds3 Pro, the Soundcore pulls ahead in raw ANC and battery longevity, though Samsung fights back with a more balanced default sound and a comfier, more secure fit. The Sony LinkBuds Fit is a closer match in price but can't match the Soundcore's noise reduction or call quality. Sennheiser's MOMENTUM True Wireless 4 delivers noticeably richer, more detailed audio—but at three to four times the cost, and with only decent ANC. For the gym bros, JBL's Endurance Peak 5 is the clear winner with its over-ear hooks and IP68 rating, even if its sound and noise cancelling fall behind. The EarFun Air Pro 4+ is probably the Liberty 4 NC's most direct rival, offering a very similar spec sheet but slightly weaker ANC. Honestly, unless you need top-tier sound or a rock-solid fitness fit, Soundcore's combo of noise cancellation, battery, and price makes the others feel overpriced.

Common Questions

Q: Is the Soundcore Liberty 4 NC good for working out?

Not really—they scored a 68.1 for fitness in our testing. While the IPX4 rating handles sweat, the earbuds tend to slip during runs or vigorous movement, so runners should consider something like the JBL Endurance Peak 4.

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

The Soundcore outlasts AirPods Pro on battery (50h vs 30h total) and arguably matches or beats them in noise cancelling, but the AirPods offer a more secure fit, better transparency mode, and tighter integration with Apple devices. For Android users or anyone prioritizing ANC, the Liberty 4 NC is a steal.

Q: Do these earbuds support LDAC?

Yes, the Liberty 4 NC supports LDAC for Hi-Res wireless audio on compatible Android phones, giving you up to three times more data transfer than standard Bluetooth codecs.

Q: How long does the battery actually last?

You get 10 hours from the earbuds with ANC on, and the case provides an extra 40 hours for 50 total. A 10-minute quick charge gives you about 4 hours of playtime.

Who Should Skip This

Fitness enthusiasts and people who prioritize all-day comfort should keep scrolling. The Liberty 4 NC's awkward fit and below-average stability make them a poor choice for gym sessions, and ears will likely protest after a few hours. If you need earbuds that lock in for runs, grab the JBL Endurance Peak 4 or a set with wingtips. Audiophiles who want a truly neutral sound straight out of the box will also be happier spending more on the Sennheiser Momentum True Wireless 4.

Verdict

If you need ear-hushing powers on a budget, buy these. The Soundcore Liberty 4 NC are the closest thing to a no-compromise noise cancelling champion under $100, and they'll make your daily commute, office grind, or cross-country flight noticeably more peaceful. The battery life alone is a game-changer—it's just wildly convenient.

That said, not everyone should click add to cart. If you're a runner or spend hours on the treadmill, the unstable fit and mediocre comfort score (70th percentile) will annoy you. And audiophiles chasing a perfectly neutral soundstage will want to look at pricier Sennheisers. But for the rest of us who just want to tune out the world for cheap, the Liberty 4 NC is an easy recommendation.
