Why you should trust this review
I have reviewed audio gear for 14 years, including time at Engadget and What Hi-Fi. For this review, I bought the Soundcore Liberty 4 NC at retail in August 2025. Anker did not provide a review unit. Over 6 months I logged roughly 180 hours of use across commute, gym, and call workloads, and ran them through the same test bench I use for the Bose QuietComfort Earbuds II and Beats Studio Buds Plus.
Every number in this review, ANC depth, battery life, leakage, fit pressure, came from my own measurements. Anker’s spec sheet was used only as a reference to compare against measured values.
How we tested the Soundcore Liberty 4 NC
For the standardized protocol, see our methodology page. For these earbuds specifically:
- ANC attenuation: Calibrated dB meter at six frequencies (50 Hz, 100 Hz, 500 Hz, 1 kHz, 5 kHz, 10 kHz). Mean attenuation 25 dB.
- Battery life: 50 percent volume, ANC on, AAC codec, played to shutdown. Mean across 3 runs: 9:48.
- Call quality: Recorded outgoing speech in 5 environments (office, café, bus interior, windy outdoor, gym) and graded against a control headset.
- Comfort: 5 hour wear test plus 4 weekly gym sessions across 6 months. Tracked any pressure points, fatigue, or fall-out events.
- Codec verification: Used Bluetooth HCI logs to confirm LDAC handshake at 990 kbps from a Pixel 9 Pro.
Who should buy the Soundcore Liberty 4 NC?
Buy these if:
- You want flagship-grade ANC and battery without a flagship price.
- You use an Android phone and want LDAC support.
- You commute on transit or in noisy offices and want isolation that actually works.
- You take calls in moderately noisy spaces, but not extremely windy ones.
Skip these if:
- You take a lot of calls outdoors in wind, get the AirPods Pro 3 instead.
- You want premium materials, the case is plastic and shows wear at 6 months.
- You have very small ear canals, the stock tip selection is limited.
Sound quality: pleasing tuning, real LDAC
Anker’s tuning leans warm and consumer friendly. Bass is full but controlled, mids are slightly recessed which softens vocals just a touch, and treble is rolled off above 12 kHz to avoid harshness. With LDAC enabled at 990 kbps from a Pixel 9 Pro, the resolution lift is real, micro detail in cymbals and reverb tails is clearly audible compared to AAC.
In a blind A/B against the Bose QuietComfort Earbuds II, 6 of 10 listeners preferred the Liberty 4 NC for casual playlists. The Bose still wins on tonal accuracy, but the Liberty 4 NC is closer than its price suggests.
Noise cancellation: 25 dB at $99
In our six-frequency lab test, the Liberty 4 NC averaged 25 dB of attenuation. That is 4 to 5 dB short of the AirPods Pro 3 and Bose QC Earbuds II, but it is the highest figure we have measured at this price point in 2 years. On a 90 minute commute on the New York 4 train, the Liberty 4 NC reduced the rumble enough that I held playback volume at 50 percent.
Wind handling is the one weak spot. Outdoor walks at 12 mph wind produced more wind noise than the AirPods Pro 3 picked up under the same conditions. If your commute is mostly outdoors and exposed, this is worth weighing.
Battery life: closer to spec than flagships
Anker rates the buds at 10 hours with ANC on. In our standardized test (50 percent volume, ANC on, AAC, no calls), we measured 9:48 across three runs. With LDAC enabled and ANC on, the figure dropped to 8:14, still beating most flagship earbuds. The case adds another 4 full charges, totalling roughly 35 hours of ANC playback.
Quick-charge is honest as well: a 10 minute top-up gave us 4 hours of playback, matching Anker’s claim within 8 minutes.
Call quality: the one place price shows
In a quiet office, the Liberty 4 NC sounds clean and natural on calls. In moderately noisy environments (café, bus), voice transmission was clear but flat. Above 60 dB of ambient noise (busy street, gym), the dual mics struggle to separate voice from background. This is the only place where you can hear the gap between $99 and $249 in 2026.

Should you buy the Soundcore Liberty 4 NC?
The Soundcore Liberty 4 NC is the budget ANC earbud to buy in 2026. After 6 months of testing, we measured 25 dB of ANC attenuation, 9:48 of real battery life with ANC on, and a clean LDAC signal at 990 kbps. Outside of call quality and ear-fit on small ears, there is almost nothing to complain about at $99.
Frequently asked questions
Are the Soundcore Liberty 4 NC worth $99 in 2026?+
Yes, after 6 months of daily use we measured ANC and battery numbers within 5 percent of flagship earbuds that cost two to three times as much. The only category where the Liberty 4 NC clearly trails the AirPods Pro 3 is wind handling and outgoing call quality.
Soundcore Liberty 4 NC vs Apple AirPods Pro 3?+
The AirPods win on ANC depth (30 dB vs 25 dB), call quality, and ecosystem integration with iPhone. The Liberty 4 NC wins on battery life (9:48 vs 6:48), LDAC support for Android, and pricing. If you live on Android, the Liberty 4 NC is the smarter buy.
How accurate is the 50-hour total battery claim?+
Anker rates the buds plus case at 50 hours with ANC off. We measured 47:12 across two full deplete cycles. With ANC on the total drops to roughly 35 hours, which still beats almost every flagship earbud.
Do the Liberty 4 NC support multipoint?+
Yes, two device multipoint works through the Soundcore app. We paired an iPhone 16 and a ThinkPad X1 Carbon for 6 months without a single re-pair. Switching audio between them takes 1.5 to 2 seconds.
Are the Liberty 4 NC good for the gym?+
Yes for indoor cardio, with the IPX4 rating handling sweat without issue across 4 weekly sessions. For outdoor running in rain, look at IPX5 or higher rated alternatives.
