Performance
The 11mm dynamic drivers push out sound that ranks at the absolute top of our database. That's not hyperbole, it's the 100th percentile. LDAC support means you're getting three times the data transfer of standard Bluetooth, and while most people won't hear the difference on a noisy bus, it matters if you're sitting in a quiet room with a decent source. The sound signature is crisp and detailed out of the box, and the HearID 2.0 customization lets you dial in a profile that actually fits your ears rather than some generic curve.
ANC performance is a standout too, landing in the top tier of what we've tested. The adaptive system adjusts in real time to your ear canal shape and the environment, which sounds like marketing fluff but genuinely helps with consistency. The catch, and there's always a catch, is high-pitched sounds. Users report that things like crying babies or clinking dishes can sneak through more than low-frequency rumble. That's pretty common for earbuds at this price, but worth knowing if you're buying these specifically to silence a noisy office. Battery life is another strong point: 10 hours without ANC, 8 with it, and the case stretches that to 50 hours total. The 10-minute quick charge giving you 4 hours is genuinely useful when you forget to plug in overnight.

vs Competition
Stacked against the Sony WF-1000XM5, the Liberty 4 NC gives up some ANC refinement and overall polish, but it's not the blowout you'd expect from the price difference. Sony's noise cancellation is still the gold standard, especially for high-frequency sounds, and their transparency mode is noticeably better. But the Anker matches or beats Sony on battery life and comes surprisingly close on sound quality. If you're a frequent flyer who wants the absolute best silence, Sony wins. If you want 85% of that for a third of the price, Anker is the obvious call.
The Samsung Galaxy Buds3 Pro is a closer fight. Samsung has better integration with Galaxy phones, a more premium build, and superior water resistance. But the Liberty 4 NC counters with better battery life, LDAC support (which Samsung skips in favor of their own codec), and a much friendlier price. The JLab JBuds Pods ANC is the budget alternative, but it's not really in the same league on sound or ANC. The JBL Live Beam 3 is a solid mid-ranger, but the Anker undercuts it on price while matching most features. The Soundcore P31i is Anker's own cheaper option, and it shows: worse sound, worse ANC, worse battery. The Liberty 4 NC is the sweet spot in Anker's lineup.

Preço
Value & Pricing
Here's where things get interesting. The Liberty 4 NC lists anywhere from $46 to $100 across US retailers, a $54 spread that's worth paying attention to. Newegg has the best deal right now, and at the low end of that range, these are an absolute steal. Even at the high end, you're still undercutting the Sony WF-1000XM5 by a huge margin while getting maybe 80% of the experience.
The value proposition is simple: you're getting top-tier sound, near-top-tier ANC, and battery life that beats most flagships, all for less than half the price of premium alternatives. The trade-offs are in the details. Fit is finicky, the app experience is good but not Apple-polished, and the build quality, while solid, doesn't feel as premium as something like the Galaxy Buds3 Pro. But if you're asking whether the extra $150 for a flagship gets you $150 more earbud, the answer here is pretty clearly no.

Overview
The Anker Liberty A3947, better known as the Soundcore Liberty 4 NC, is one of those products that makes you wonder why anyone pays double for flagship earbuds. For somewhere between $46 and $100 depending on where you shop, you get adaptive ANC, LDAC support, multipoint, wireless charging, and battery life that embarrasses most of the premium competition. That's a lot of tech for the price of a nice dinner.
Who's this for? Travelers who want to mute airplane drone without spending AirPods Pro money. Commuters who need reliable multipoint between a laptop and phone. Budget-conscious buyers who still want Hi-Res audio codecs and a proper companion app. It's not really aimed at gym rats, and the IPX4 rating confirms that. Light rain and sweat, sure. A full workout? Maybe look elsewhere.
The interesting part is how Anker positioned this. It's not a stripped-down budget bud. It's a feature-stuffed mid-ranger that undercuts Sony and Samsung by a wide margin. The 98.5% noise reduction claim is marketing math, but the real-world ANC performance lands in the top tier of our database. That's the story here: flagship features at a price that makes you double-check the listing.
Common Questions
Q: How good is the noise cancellation really?
The ANC ranks in the top tier of our database, and it's genuinely impressive for the price. It handles low-frequency noise like airplane engines and traffic rumble extremely well. The weak spot is high-pitched sounds, things like crying babies, clinking dishes, or sharp voices can still cut through. If you're mostly trying to block out commute noise or office chatter, you'll be happy. If you need to silence a nursery, these won't fully get you there.
Q: Will these stay in my ears during workouts?
Probably not reliably. The IPX4 rating means they can handle sweat and light rain, but the fit with stock ear tips is a common complaint. Many users report needing third-party tips to get a secure seal, and even then, these aren't designed for high-movement activities. If fitness is your main use case, look at something with ear hooks or a more secure fit like the JLab JBuds or dedicated sport earbuds.
Q: Do they work well with iPhones?
They work, but with a caveat. You get Bluetooth 5.3 connectivity, the Soundcore app, and all the core features like ANC and EQ customization. The main drawback is that iPhones don't support notification sounds through these earbuds, which is a recurring complaint from iOS users. If you rely on hearing message alerts or app notifications in your ears, that's a real annoyance. For music, calls, and ANC, they're fine on iPhone.
Q: How does the battery life compare to other earbuds?
It's one of the best in the category. You get 10 hours on a single charge with ANC off, 8 hours with ANC on, and the case extends that to 50 hours total. The 10-minute quick charge giving you 4 hours of playback is genuinely useful. For comparison, most earbuds in this price range top out around 6-7 hours per charge, and even premium options like the Sony WF-1000XM5 don't match the Liberty 4 NC's stamina.
Who Should Skip This
If you're a serious gym person or runner, these aren't for you. The fit issues with stock tips are well documented, and the IPX4 rating is really just splash protection, not workout-grade durability. You'll spend half your session pushing them back into your ears. Look at something with ear hooks or a more secure in-ear design instead, the JLab JBuds line or dedicated sport earbuds are better suited for that.
iPhone users who depend on notification sounds should also think twice. The lack of iOS notification support is a persistent annoyance that Anker hasn't fixed. If you're deep in the Apple ecosystem and want that seamless experience, the AirPods Pro 2 or even the Beats Fit Pro will serve you better, though you'll pay significantly more. And if transparency mode is a priority, like you need to hear announcements at the airport or conversations while wearing them, the Liberty 4 NC's transparency mode is mediocre at best. The Sony WF-1000XM5 or AirPods Pro 2 are the clear winners there.
Verdict
If you're looking for the best noise-cancelling earbuds under $100, stop scrolling. The Liberty 4 NC is the one to beat. The combination of top-tier sound, excellent ANC, and marathon battery life at this price is genuinely rare. Buy them for commuting, travel, or office use, and you'll be thrilled. The multipoint connection is a lifesaver if you bounce between a work laptop and a personal phone, and the wireless charging case is a nice touch that even some flagships skip.
But if you're a gym person, look elsewhere. The IPX4 rating means sweat is technically fine, but the fit issues with stock tips make these a poor choice for anything involving movement. Same goes if you're an iPhone user who relies on notification sounds, the lack of iOS notification support is a real annoyance. And if you need the absolute best transparency mode for situational awareness, the Sony WF-1000XM5 or AirPods Pro 2 are still the champs. For everyone else, the Liberty 4 NC is the easiest recommendation in wireless earbuds right now.
