The Soundcore Liberty 4 NC Black is the mid-priced earbud in soundcore’s Liberty range that brings strong noise cancelling within reach. Its Adaptive ANC 2.0 uses a high-sensitivity in-ear sensor to adjust cancelling to your ear and surroundings, and soundcore advertises noise reduction of up to 98.5%. Each earbud has an 11mm driver, LDAC is available for Hi-Res wireless audio on Android 8.0 and later, six microphones handle calls, and the case charges wirelessly. With ANC off, soundcore rates it at up to 10 hours per charge and 50 hours with the case.

Adaptive ANC 2.0 and the 98.5% figure
The in-ear sensor of the Liberty 4 NC Black checks how well the tips seal and how loud the surroundings are, then sets the cancelling strength. soundcore’s headline is noise reduction of up to 98.5%, but the product page does not state the test conditions. As with any ANC earbud, steady low sounds such as engines, bus rumble and air conditioning are reduced far more than voices or sharp sounds. soundcore also notes that cancelling can feel weaker in very noisy places at high volume. Read the number as a best case for low drone rather than a promise of silence in an open office.
Fit decides the result
Noise cancelling depends on the seal. soundcore suggests trying different tip sizes, and even mixing sizes between left and right ears, until both feel sealed. The soundcore app includes a fit test, and running it once after unboxing is worth the minute it takes: a loose tip lets in noise the ANC cannot catch and also thins the bass. Each earbud weighs 5.2 g, light enough for long commutes. IPX4 protects against sweat and splashes during workouts, but not against swimming or dust.
11mm drivers, LDAC and HearID 2.0
Each Liberty 4 NC Black earbud has an 11mm driver, larger than most earbuds in this class. On Android 8.0 or later, LDAC can be switched on in the app for Hi-Res wireless streaming after a firmware update; iPhones do not support LDAC. Turning LDAC on ends the multipoint connection and shortens battery life. HearID 2.0 builds a personal sound profile from a short hearing test, and you can still adjust the EQ by hand. For podcasts and calls the standard codec is enough; LDAC is worth turning on for focused listening at home.
Battery life by mode
soundcore’s lab figures, measured at 50% volume with default settings, show how much each mode of the Liberty 4 NC Black costs. ANC off: 10 hours per charge and 50 hours with the case. ANC or Transparency on: 8 and 40 hours. LDAC with ANC off: 6 and 30 hours. LDAC with ANC on: 5 and 25 hours. Calls last 4.5 hours with ANC off and 4 hours with it on. The earbuds recharge in about 1.5 hours; the case takes about 3 hours from a wall charger or about 3.5 hours on a wireless pad, and 10 minutes of charging gives 4 hours.
Why the black version
The Liberty 4 NC Black is the safest colour in the range. Its dark matte finish keeps fingerprints and the light scuffs on the case edge hard to see, so the earbuds still look tidy after months in a pocket or a gym bag. It suits office calls, commuting and workouts alike, and it does not show ear wax or skin oil on the stems the way light colours do. Six microphones with an AI algorithm handle calls, and multipoint lets the earbuds stay connected to a phone and a laptop at once, as long as LDAC is off.
Who This Is Not For
The Soundcore Liberty 4 NC Black is not for swimmers or dusty outdoor work: IPX4 covers splashes and sweat only. LDAC is Android-only, ends multipoint and drops battery life to 5 hours per charge with ANC on. Anyone expecting the 98.5% figure to silence voices in an open office will be disappointed, because ANC works best on low, steady noise. If you dislike sealed in-ear tips, an open-fit design will be more comfortable.
