Anker Soundcore Liberty 4 NC TWS Earbuds

Anker Soundcore Liberty 4 NC TWS Earbuds

Anker's noise-cancelling model sits a step below its flagship and keeps most of what matters: adaptive cancellation, LDAC and a fifty-hour total. Compare it across our earbuds and TWS.

Adaptive cancellation

The Liberty 4 NC measures the noise around you and scales cancellation to match, instead of running at a fixed strength. That matters for comfort more than for performance: full-power cancellation in an already-quiet room is what produces the pressure sensation people describe as ear fatigue, and an adaptive system simply does not do it. It also samples how well the earbuds are sealing in your ear and compensates, which is the difference between a specification figure and what you actually get.

LDAC and the 11mm drivers

LDAC carries roughly three times the data of the default Bluetooth codec, and the Liberty 4 NC is Hi-Res Wireless certified as a result. It needs a recent Android phone — iPhones do not support LDAC and fall back to AAC. Behind the codec are 11mm drivers, larger than most, and the Soundcore app provides EQ adjustment plus a hearing test that tunes the sound to your ears rather than to an average.

Battery and fast charge

Ten hours from the earbuds and fifty in total with the case, rated with cancellation off — running it continuously reduces both. More useful day to day is the fast charge: five minutes in the case gives roughly four hours of playback, which covers the case where you notice they are flat as you are leaving.
