Affordable noise cancelling used to mean giving up most of the important stuff. You got quiet, maybe, but the sound was muddy, the battery died before lunch, and the case felt like a cheap afterthought. The Soundcore Liberty 4 NC arrived promising to change that equation, and after spending a full week with them on trains, in offices, and through long sessions of focused listening, I can report that the promise is largely kept.

The Liberty 4 NC sit below the flagship Liberty 4 in Soundcore line, and the "NC" stands for noise cancelling, the feature this pair leans on hardest. With a claimed 98.5 percent noise reduction, adaptive ANC that reacts to your environment, Hi-Res certified sound with LDAC support, and a combined 50 hour battery, the spec sheet reads like a premium product. The price does not. That gap is exactly where I focused my testing.
This review covers the design, the adaptive noise cancelling, the sound, the battery, the call quality, and how the Liberty 4 NC compare with the bigger names in the category. If you are trying to decide whether a budget ANC pair is enough for you, this is the review to read.
Design and Build
Soundcore has settled into a clean design language, and the Liberty 4 NC wear it well. The earbuds are stem style, with a matte finish on the outer surface and a subtle two tone look that reads more expensive than the price tag. They are not the smallest earbuds on the market, but they are light, and the sculpted shape sits naturally in the ear without the pressure that some budget pairs create. The included silicone tips come in four sizes.
The charging case is where the budget reality shows. It is a rounded, pebble shaped case that feels sturdy and closes with a satisfying click, but it is noticeably larger than the cases that come with flagship earbuds. That is the trade for the huge battery capacity, and it is one I would accept, because the case disappears into a bag or pocket anyway.
The controls are touch sensitive on both earbuds. A tap handles play and pause, double taps skip tracks, and presses manage volume and ANC modes, with every action customizable in the Soundcore app. The touch panels respond reliably, and the press and hold gesture for switching between noise cancelling and transparency worked without accidental triggering.
Key Features
The headline feature is the adaptive noise cancelling, which Soundcore claims reduces ambient noise by up to 98.5 percent. The system listens to your surroundings and automatically scales the cancellation strength between three levels, shifting from strong cancellation in a noisy street to a lighter touch in a quiet room. In practice the adaptive behavior is subtle but real, and the wind reduction mode is a genuine standout for outdoor use.
Sound quality is anchored by 11mm dynamic drivers with Hi-Res certification and LDAC support on Android devices. LDAC transmits nearly three times the data of standard Bluetooth audio, which translates to a noticeably cleaner, more detailed presentation with a capable source. The Soundcore app adds a full EQ with custom presets, plus HearID, a feature that runs a quick hearing test and tunes the output to your ears. It is marketing you might expect to ignore, but the result was a flatter, more personal sound that I kept on.
Battery life is the other big number. The earbuds run about 10 hours per charge with ANC on, and the case pushes the total to around 50 hours. That is class leading, and it means the case can go a full work week before it needs a charge, even with heavy daily use. Bluetooth 5.3 with multipoint lets the earbuds stay connected to a phone and a laptop at the same time, and the six microphones with AI noise reduction handle voice pickup.
Real-World Performance
The best test for ANC is a real commute, so that is where I started. On a train line with rumbling tracks and constant announcements, the Liberty 4 NC cut the drone dramatically. The cancellation is not at the level of the Sony and Bose flagships, which silence everything, but for a pair at this price it is remarkably effective. Office noise, keyboard clatter, and HVAC hum all faded into the background, and I found myself listening at lower volumes.
Sound quality followed the same pattern. The signature is warm and bass forward, which suits pop, hip hop, and electronic music beautifully, and the LDAC connection gave the top end room to breathe on acoustic tracks and vocals. This is not a reference grade neutral sound, but it is an energetic, fun sound with more detail than the price suggests.
Call quality held up better than most budget pairs. The six microphones with AI noise reduction kept my voice clear in a quiet room and even in traffic, though on the noisiest streets callers could still hear some background rumble. For the daily call volume most people handle, the performance is more than acceptable.
Battery life delivered on the claim. I ran the earbuds for about three hours a day across the test week, and the case indicator still showed more than half remaining at the end. The wireless charging case is a convenience I used constantly, and the ten minute quick charge feature added roughly four hours of playback when I was in a hurry, which is a genuinely useful emergency feature.
Pros and Cons
Pros:
- Effective adaptive noise cancelling for the price
- Hi-Res certified sound with LDAC support
- 50 hour combined battery life with wireless charging
- Multipoint Bluetooth 5.3 connects two devices
- Comfortable fit with four tip sizes
- Strong call quality with six microphones
- Full EQ and HearID tuning in the app
Cons:
- Case is bulkier than flagship rivals
- No wireless charging in every region of the market
- ANC not quite at Sony or Bose level
- Bass forward tuning not for purists
How It Compares
The natural comparison is against the more expensive AirPods Pro and the flagship Sony and Bose pairs, but the fairer one is with Soundcore own step up, the Liberty 4. The table below lines up the two Soundcore pairs so the choice is clear.
| Feature | Liberty 4 NC | Soundcore Liberty 4 |
|---|---|---|
| Price | Budget friendly | Mid range |
| Noise cancelling | Adaptive, strong for price | Adaptive, similar levels |
| Battery life | Up to 50 hours total | Up to 28 hours total |
| Sound | Hi-Res, LDAC | Hi-Res, LDAC, spatial audio |
| Extra sensors | None | Heart rate sensor |
| Wireless charging | Yes | Yes |
The Liberty 4 add spatial audio and a heart rate sensor for a higher price, but the NC pair wins on battery life and price. Against the Sony WH-1000XM5 at three times the cost, the Liberty 4 NC cannot match the sheer silence of Sony best ANC, but they deliver a strong slice of that experience for a fraction of the money. For most people the NC pair is the smarter buy.
Who Should Buy It
The Liberty 4 NC are for the daily commuter who wants peace and quiet without paying premium prices, for the office worker who needs to block out an open plan floor, and for anyone who hates charging gadgets and wants a battery that lasts the week. They are also a strong pick for Android users who want LDAC, because that high res connection works only on Android devices.
Skip them if you demand the absolute best noise cancelling, because the Sony and Bose flagships still win that fight, or if you prefer a neutral, analytical sound signature. You can check the current price of the Soundcore Liberty 4 NC on Amazon to see how they fit your budget.
How We Test
I tested the Liberty 4 NC for one week across commutes by train and foot, open plan office sessions, calls, and a movie on a tablet. I measured battery life by running continuous playback with ANC on until the earbuds drained, then tracking recharges through the case. I compared noise cancelling against the Sony WH-1000XM5 and a pair of AirPods Pro, and I used the Soundcore app to run the HearID test and tune the EQ. For a deeper look at how LDAC compares with other Bluetooth codecs, SoundGuys has a thorough explanation of LDAC and wireless audio that is worth reading.
