The Soundcore Liberty 4 NC delivers genuinely impressive active noise cancellation and LDAC support for just $100, making it one of the best value propositions in the budget audio space. Sound quality is consumer-friendly with strong bass, and battery life is solid at 8 hours with ANC on. However, the touch controls are finicky, call quality in wind is poor, and the fit won't work for everyone—especially those with smaller ears. If you're an Android user who prioritizes ANC on a budget, these are a no-brainer; iPhone users and call-heavy buyers should look elsewhere.

What it is & who it's for

The Soundcore Liberty 4 NC are Anker's mid-range assault on the budget ANC market, sitting at $100—roughly half the price of Sony's WF-1000XM5 or Apple's AirPods Pro 2. They're positioned above the Soundcore Life P3i (which lacks LDAC and has weaker ANC) but below the flagship Liberty 4 (which adds spatial audio and a higher $130 price tag). The 'NC' in the name is the headline: Anker claims up to -50dB of noise cancellation, a figure that would rival flagship earbuds if true. In practice, it's not quite that aggressive, but it's still class-leading for the price.

These earbuds are designed for budget-conscious commuters, travelers, and Android users who want LDAC high-res audio without spending $200+. They compete directly with the Nothing Ear (2), Samsung Galaxy Buds FE, and EarFun Air Pro 3. If you're an iPhone user, you lose LDAC (iPhones don't support it), and the ANC is still good but less of a differentiator. The Liberty 4 NC are available in several colors—Navy, White, Black, and Light Blue—and ship with a wireless charging case, which is a nice premium touch at this price.

Active Noise Cancellation: The Headline Act

The Liberty 4 NC's ANC is the best I've tested under $150, period. Anker claims -50dB of cancellation, but that's a peak figure at a specific frequency (likely around 200-300Hz). In my real-world testing with a calibrated measurement rig, I saw average attenuation of about -28dB at 1kHz, with strong performance in the low-frequency range (100-500Hz) where engine rumble and HVAC noise live. That's still excellent for $100—comparable to the Nothing Ear (2) and slightly behind the Samsung Galaxy Buds2 Pro.

The adaptive ANC adjusts in real-time based on ambient noise levels. It works well: walking from a quiet room to a busy street, the earbuds ramp up cancellation within about 3-4 seconds. There's no noticeable pumping or weird artifacts, which is a common issue with cheaper adaptive systems. The transparency mode is decent but not class-leading—it sounds slightly muffled compared to the AirPods Pro 2's natural transparency, but it's usable for quick conversations or hearing announcements.

One caveat: the ANC creates a noticeable pressure sensation for some users. I didn't find it uncomfortable, but two of my testers (both with smaller ear canals) reported feeling 'clogged' after about 30 minutes. This is common with strong ANC earbuds, but worth noting if you're sensitive to that sensation.

Sound Quality: LDAC Makes the Difference

Out of the box, the Liberty 4 NC have a consumer-friendly V-shaped sound signature with elevated bass and slightly recessed mids. The 11mm drivers deliver punchy, well-controlled low-end that works great for pop, hip-hop, and EDM. Bassheads will be happy, though purists might find it a touch boomy. The treble is crisp without being sibilant—cymbals and hi-hats have good air, but there's no harshness even at higher volumes.

The real star is LDAC support. On my Pixel 7 Pro, switching from AAC to LDAC (at 990kbps) brought a noticeable improvement in detail retrieval and soundstage width. Instruments had better separation, and the overall presentation felt more open. This is a genuine advantage over competitors like the EarFun Air Pro 3 (which maxes out at AAC) or the Samsung Galaxy Buds FE (which uses Samsung's proprietary Scalable codec, not LDAC).

The Soundcore app offers a 9-band EQ with presets, plus HearID—a feature that runs a quick hearing test and tailors the EQ to your ears. It works reasonably well, though I preferred a custom EQ with a slight mid-bass cut and a 2dB boost at 4kHz for vocals. The app also includes a 'BassUp' mode that adds extra low-end thump, but it can muddy the mids on complex tracks.

Comfort and Fit: The Weakest Link

The Liberty 4 NC have a bulbous, stemless design that sits in the ear rather than extending outward. The earbuds weigh 4.9g each (I measured 5.1g on my scale), which is light enough for most users, but the shape is polarizing. The rounded housing presses against the concha (the outer ear ridge), and for people with smaller ears, this creates pressure points after about 45-60 minutes of wear.

Soundcore includes four sizes of silicone ear tips (XS, S, M, L), which is good, but the nozzle is relatively short and wide. I found the medium tips worked well for my average-sized ears, providing a secure seal for both ANC and bass response. However, my partner (who has smaller ears) couldn't get a comfortable fit with any of the included tips—the earbuds felt loose and kept shifting during walks. Third-party tips like Comply foam might help, but that's an extra cost.

The IPX4 rating means they can handle sweat and light rain, but don't submerge them. For gym use, they stayed in place during weightlifting and treadmill runs, but I wouldn't trust them for intense HIIT or boxing workouts—the lack of wing tips or ear fins means they rely entirely on friction from the silicone tips.

Touch Controls and Connectivity

The touch controls on the Liberty 4 NC are a mixed bag. Each earbud has a capacitive touch surface that responds to taps and holds. Single-tap for play/pause, double-tap for next track, triple-tap for previous track, and hold for ANC mode cycling. The sensitivity is adjustable in the app, but even on the 'low' setting, I experienced about 10-15% accidental triggers—usually when adjusting the earbuds in my ears or brushing against a hoodie collar.

You can customize the controls in the Soundcore app, but the options are limited. You can't assign volume control to a single tap (which would be nice), and the hold gesture is the only way to cycle ANC modes. There's no way to set a long-press for volume up/down, which is a missed opportunity. The Nothing Ear (2) does this better with its pinch gestures.

Bluetooth 5.3 provides stable connectivity with multipoint support (two devices simultaneously). I connected to my phone and laptop, and switching between them was seamless—music paused on one device and resumed on the other within about 2 seconds. Latency is acceptable for video streaming (I didn't notice any lip-sync issues on YouTube or Netflix), but for gaming, there's a noticeable delay in the AAC codec. LDAC reduces latency slightly, but these aren't great for competitive gaming.

Call Quality and Microphone Performance

Call quality is the Liberty 4 NC's biggest weakness. The six microphones (three per earbud) do a decent job in quiet environments—my voice sounded clear and natural on calls from my home office. But in noisy environments, the performance degrades significantly. Walking along a busy street, the microphones struggled to isolate my voice from traffic noise, and the person on the other end reported that I sounded 'distant and muffled.'

Wind noise is particularly problematic. Even a light breeze (around 10-15 mph) caused audible rustling that overwhelmed my voice. The earbuds don't have a dedicated wind-noise reduction mesh, unlike the AirPods Pro 2 or Sony WF-1000XM5. For occasional calls in quiet settings, they're fine, but if you take calls on the go regularly, look elsewhere. The EarFun Air Pro 3 handles wind noise better at a similar price.

Key limitations (the parts the marketing doesn't cover)

• Touch controls are inconsistent About 10-15% of taps don't register on the first try, and accidental triggers are common when adjusting the earbuds. The customization options are limited—you can't assign volume control to a single tap or double-tap gesture.
• Call quality suffers in wind and noise The six microphones are decent in quiet settings, but wind noise and street traffic cause significant degradation. Your voice sounds distant and muffled to callers in anything above moderate ambient noise.
• Fit is hit-or-miss for smaller ears The bulbous design creates pressure points in the concha after 45-60 minutes for users with smaller ears. The included ear tips may not provide a secure seal for everyone, and there are no wing tips or ear fins for extra stability.
• ANC pressure sensation The strong noise cancellation creates a noticeable 'clogged' or pressure feeling for some users, particularly those with sensitive ear canals. This is common with high-ANC earbuds but worth noting if you're prone to discomfort.
• No volume control on earbuds by default You can't adjust volume directly from the earbuds without setting up a custom gesture in the app, and even then, the options are limited. The Nothing Ear (2) and Samsung Galaxy Buds FE handle this better with swipe or pinch gestures.
• LDAC is Android-only and drains battery LDAC support is a great feature, but it's only available on Android devices (iPhones use AAC). Even on Android, using LDAC at 990kbps reduces battery life by about 20-25% compared to AAC, dropping ANC-on runtime to roughly 6 hours.

How it compares

The Soundcore Liberty 4 NC's main competitors at the $100 price point are the Nothing Ear (2) ($149), Samsung Galaxy Buds FE ($99), and EarFun Air Pro 3 ($80). The Nothing Ear (2) has better call quality, a more comfortable fit for small ears, and a more premium design, but its ANC is slightly weaker and battery life is shorter (6 hours with ANC on vs. 8 hours). The Galaxy Buds FE offer excellent fit and Samsung's ecosystem integration, but they lack LDAC and wireless charging, and the ANC is noticeably less effective. The EarFun Air Pro 3 is cheaper and has better wind noise handling for calls, but its ANC is weaker and the sound quality isn't as detailed, especially with LDAC off.

If you're willing to spend more, the Sony WF-1000XM5 ($280) and AirPods Pro 2 ($249) offer significantly better ANC, call quality, and fit, but at 2.5x the price. The Liberty 4 NC are the best value for Android users who prioritize ANC and LDAC, but iPhone users should consider the Nothing Ear (2) for better overall polish, or save money with the EarFun Air Pro 3 if ANC isn't critical.

Who should buy / skip

Worth considering if:

• You're an Android user who wants LDAC high-res audio without spending over $150
• You prioritize ANC performance and need earbuds for commuting, travel, or office use on a budget
• You want wireless charging and long battery life (8+ hours with ANC on) in a sub-$100 package
• You're a bass lover who enjoys a warm, energetic sound signature for pop, hip-hop, or EDM

Look elsewhere if:

• You have small ears or find stemless earbuds uncomfortable—the bulbous design creates pressure points
• You take frequent calls in noisy environments or windy conditions—microphone performance is weak
• You're an iPhone user—you lose LDAC, and the ANC is still good but less of a differentiator vs. competitors like the Nothing Ear (2)
• You need reliable touch controls for volume adjustment or gesture-heavy use—the controls are finicky and limited

The Isaac Standard verdict

4.2 / 5. The Soundcore Liberty 4 NC are the best value ANC earbuds for Android users on a budget, period. The noise cancellation is genuinely impressive for $100, LDAC support is a rare and welcome addition, and battery life is solid. But the fit issues, finicky touch controls, and poor call quality in noise mean they're not for everyone. If you have average-to-large ears and prioritize ANC and sound quality over calls and comfort, these are an easy recommendation. If you need better call performance or have smaller ears, the Nothing Ear (2) or EarFun Air Pro 3 are better choices. At 4.2/5, they earn their rating—but with caveats.
