Liberty 4 NC or CMF Buds? For noise cancelling?
If noise cancelling is your main priority, the Anker Soundcore Liberty 4 NC is generally the better choice than the original CMF Buds. It offers adaptive noise cancellation, adjustable settings, and more control over how much outside sound you hear. The CMF Buds can still be a good budget option if you want basic noise reduction without spending as much.
Noise Cancelling: Liberty 4 NC vs. CMF Buds
The biggest difference is how much control each pair gives you over background noise. The Soundcore Liberty 4 NC uses Adaptive ANC 2.0, which adjusts noise cancellation to your surroundings and ear fit. The original CMF Buds also offer active noise cancellation, rated at up to 42 dB by the manufacturer.
However, these advertised figures are not directly comparable because the companies may use different testing methods.
| Noise-cancelling feature | Soundcore Liberty 4 NC | CMF Buds |
|---|---|---|
| Active noise cancellation | Adaptive ANC 2.0 | Up to 42 dB claimed |
| Adjustable ANC | Five levels | Adjustable ANC modes |
| Transparency mode | Yes, two modes | Yes |
| Best reason to choose it | More control over noise | Lower-cost noise cancellation |
| Overall pick for ANC | Winner | Good budget alternative |

Which Earbuds Handle Everyday Noise Better?
Airplane and bus noise
The Liberty 4 NC is the stronger choice to consider for travel. Its adaptive system is designed to respond to changing background noise, making it useful for reducing steady engine sounds during flights or bus rides. The CMF Buds can also reduce some of this noise, but the advertised 42 dB figure alone cannot establish how they compare in real-world use.
Office and study environments
Both earbuds can help reduce distractions from fans, air conditioners, and other steady sounds. The Liberty 4 NC is appealing if you want to adjust cancellation for different environments.
For example, someone studying in a busy coffee shop might prefer stronger cancellation to focus on a task. Someone working in a quieter room may need only moderate cancellation.
Neither pair will completely remove nearby conversations, sudden sounds, or every type of background noise.
Street noise and public spaces
Both models offer transparency modes, which let outside sound pass through when you need to hear people or announcements. The Liberty 4 NC provides two transparency modes, giving you additional control.
Remember that noise-cancelling earbuds can make you less aware of traffic and other hazards. Lower the volume and stay alert when walking near roads.
Battery Life and Other Features
Noise cancellation is the main reason to compare these earbuds, but battery life and sound customization also matter.
| Feature | Soundcore Liberty 4 NC | CMF Buds |
|---|---|---|
| Battery per charge | Up to 10 hours | Up to 8 hours |
| Total battery with case | Up to 50 hours | Up to 35.5 hours |
| Sound customization | Adjustable EQ and HearID 2.0 | Nothing X app and sound controls |
| Wireless charging | Yes | Not listed as a supported feature |
| Water resistance | IPX4 | Check the exact model’s specifications |
These are manufacturer-stated maximums, and actual battery life can be shorter when ANC is enabled or other features are in use.
The Liberty 4 NC also supports LDAC high-resolution wireless audio with compatible Android devices. That is a useful extra if you care about audio customization as well as noise cancellation.
Is the Liberty 4 NC Worth Paying More For?
The answer depends on how often you use noise cancellation.
- Choose the Liberty 4 NC if you travel often, study in noisy places, work around steady background noise, or want more control over ANC and sound settings.
- Choose the CMF Buds if you want active noise cancellation at a lower price and do not need all the extra features.
For example, a frequent airline traveler may benefit from the Liberty 4 NC’s adaptive cancellation and longer advertised battery life. Someone who mostly listens to music at home may find the more affordable CMF Buds sufficient.
The Liberty 4 NC launched at a US list price of $99.99, but current prices and discounts can vary. Compare the actual checkout prices before deciding.

Are Liberty 4 NC better than CMF Buds for noise cancelling?
The Liberty 4 NC is my overall pick because it offers adaptive noise cancellation and more adjustment options. The CMF Buds remain a reasonable alternative, but advertised decibel ratings alone do not prove which model cancels more noise.
Are CMF Buds good for airplane travel?
Yes, the original CMF Buds offer ANC that can help reduce steady airplane cabin noise. However, if frequent travel and noise cancellation are your main priorities, the Liberty 4 NC is the model I would consider first.
Should I buy Liberty 4 NC or CMF Buds on a budget?
The CMF Buds are the more budget-focused option, while the Liberty 4 NC offers additional noise-control features and longer advertised battery life. If the price difference is small during a sale, the Liberty 4 NC may offer better overall value.
Final Verdict
For noise cancelling, the Liberty 4 NC is the better all-around choice because of its adaptive ANC, adjustable settings, and longer advertised battery life. The CMF Buds make more sense when keeping the cost down is your main concern.
One practical tip: try different ear-tip sizes before judging either model’s noise cancellation. A secure, comfortable seal can make a noticeable difference in how much outside sound your earbuds block.
