The Soundcore Liberty 4 NC Navy Blue is Anker’s mid-range noise cancelling earbud in its deepest colour: a dark blue with a slight sheen, used on both the buds and the charging case. Under the finish it is the same Liberty 4 NC as every other colour. Anker rates its Adaptive ANC 2.0 at up to 98.5% noise reduction, a figure certified by SGS for the deepest frequency band. You get 11mm drivers, LDAC streaming on Android, six beamforming microphones, Bluetooth 5.3 multipoint and up to 10 hours per charge, or 50 hours with a case that also charges wirelessly.

Navy Blue: a colour that is not black
Most earbuds come in black or white, and the Soundcore Liberty 4 NC Navy Blue is for people who want something a little different without anything loud. In daylight the deep blue is clearly visible; indoors or in the evening it can pass for near-black, so it suits work as easily as weekends. It matches denim, navy suits, blue phone cases and dark leather bags. The dark Soundcore Liberty 4 NC Navy Blue case also hides pocket dirt and the grey marks that a white case picks up, which makes it a practical choice for anyone who carries earbuds loose in a trouser pocket or a work bag every day.
Adaptive ANC 2.0 for travel and the commute
On the Soundcore Liberty 4 NC Navy Blue, Adaptive ANC 2.0 reads both your surroundings and how well the ear tips seal, then sets the cancellation level to match. Anker quotes up to 98.5% noise reduction, certified by SGS in the deepest frequency band, so the low hum of engines and air conditioning is where it works best. On top of the automatic mode there are five manual ANC levels and four travel presets named Plane, Train, Bus and Taxi. Two transparency modes bring voices and announcements back when you need them, for example at a gate or on a station platform.
Sound: 11mm drivers, LDAC and HearID 2.0
Each earbud uses an 11mm custom-tuned driver. On Android phones that support it, the Soundcore Liberty 4 NC Navy Blue streams LDAC at up to 990 kbps, compared with 328 kbps for standard SBC; you switch LDAC on inside the soundcore app. iPhones use AAC, since Anker states LDAC is Android-only. The app also runs HearID 2.0, a short hearing test that creates a personal sound profile, and gives you 22 EQ presets plus a fully adjustable EQ for anyone who likes to tune the sound by hand.
Battery and the wireless charging case
For the Soundcore Liberty 4 NC Navy Blue, Anker rates playtime at up to 10 hours per charge and up to 50 hours with the case; the product page bases the case figure on playing 1,000 three-minute songs and does not give separate numbers with ANC on, so expect less with heavy noise cancelling. A 10-minute charge gives up to 4 hours of playback. The case charges over USB-C or on any wireless charging pad, so you can leave it on the same pad you use for your phone overnight and pick it up full in the morning.
Calls, multipoint and everyday use
For calls, six beamforming microphones work with an AI algorithm that separates your voice from wind and traffic. Bluetooth 5.3 multipoint keeps the Soundcore Liberty 4 NC Navy Blue connected to two devices, such as a phone and a laptop, so a call can come in while you are watching a video on the other device. The IPX4 rating of the Soundcore Liberty 4 NC Navy Blue covers sweat and splashes, enough for the gym or a walk in light rain, but the earbuds are not meant for swimming or showers.
Who This Is Not For
The Soundcore Liberty 4 NC Navy Blue is not for iPhone owners who specifically want Hi-Res wireless, since LDAC works only on Android. IPX4 covers sweat and splashes but has no dust rating and no protection for swimming. Anker does not publish battery life with ANC switched on, so the 10-hour figure will drop with heavy noise cancelling. If you want a colour that stands out, the Light Blue or Pink versions are brighter; this one is deliberately dark.
