Soundcore Liberty 4 NC Navy Blue

Key Features and Benefits

Adaptive ANC 2.0 with Up to 98.5% Noise Reduction: A high-sensitivity in-ear sound sensor, the 11mm driver, and a noise isolation chamber work together to cancel ambient sound across a wide frequency range. Adaptive ANC 2.0 continuously recalculates based on your ear canal shape and the environment, so the suppression level adjusts automatically as surroundings change. Five selectable ANC levels give further manual control, and dedicated transport modes for plane, train, bus, and taxi tune the cancellation curve to each setting’s typical noise profile.
11mm Custom-Tuned Drivers with LDAC Hi-Res Audio: The 11mm drivers deliver an extended frequency response from 20 Hz to 40,000 Hz — beyond the threshold of standard Bluetooth audio. When connected via LDAC to an Android 8.0+ device, the Liberty 4 NC transfers up to three times more audio data than standard SBC, preserving more harmonic detail in complex recordings. The HearID 2.0 hearing test additionally creates a personal EQ profile matched to your hearing response, so the sound adapts further to the individual listener.
10-Hour Battery with Wireless Case Charging: In normal mode the earbuds run for 10 hours per charge, extending to 50 hours total with the case. ANC-on playback reaches 8 hours per earbud and 40 hours total. Furthermore, a 10-minute charge provides four additional hours of playback, and the case supports both USB-C wired and Qi wireless charging — a feature absent from several competing earbuds at this price.
6-Mic Beamforming with AI Call Enhancement: Six beamforming microphones feed an AI noise reduction algorithm that targets your voice while suppressing background sound. The system reduces wind noise and ambient noise during calls, making the Liberty 4 NC more reliable than two-mic setups in moderately noisy outdoor environments. Wear detection also pauses audio automatically when you remove an earbud, and resumes on reinsertion.
HearID 2.0 and 22-Preset EQ: The Soundcore app runs a short hearing profile test and generates a personalised EQ curve. Alternatively, 22 preset EQ profiles cover bass-forward, vocal, classical, and other signatures, or an 8-band manual equaliser provides full custom control. The app also unlocks ANC level adjustment, transparency mode tuning, control remapping, spatial audio settings, and firmware updates.

Soundcore Liberty 4 NC Navy Blue – Adaptive ANC Earbuds with LDAC and Wireless Charging

The Soundcore Liberty 4 NC Navy Blue is a pair of true wireless noise-cancelling earbuds designed for commuters, travellers, and everyday listeners who want capable ANC, hi-res wireless audio, and long battery life without flagship pricing. The Navy Blue colourway — also referred to as Cosmic Blue or Dark Navy in some markets — carries a subtle iridescent finish that distinguishes it from the standard Velvet Black. Hardware throughout is identical to all other Liberty 4 NC colour variants.

⚠️ LDAC is Android-only. LDAC Hi-Res wireless streaming requires Android 8.0 or later. iOS devices use SBC or AAC only — LDAC is unavailable on iPhone or iPad.

⚠️ LDAC and multipoint cannot run simultaneously. Enabling LDAC on the Soundcore app will disable dual-device connection. You must choose one or the other for each listening session.

⚠️ No wall charger included. The box contains earbuds, charging case, a USB-C cable, and ear tips in four sizes. A USB power adaptor is not included.

Use Cases

Commuting and Public Transport

The five ANC levels and dedicated transport modes let you tune noise suppression specifically to trains, buses, or flights rather than relying on a generic setting. Since Adaptive ANC 2.0 recalculates continuously, the earbuds adjust as you move between a loud platform and a quieter carriage without manual intervention. Additionally, the 50-hour total battery means a week of typical commuting use before the case needs recharging.

Remote Work and Office Environments

Open-plan offices and home setups with variable background noise suit Adaptive ANC 2.0 well — the algorithm responds to changing conditions rather than holding a fixed cancellation curve. The 6-mic beamforming array keeps your voice clear on calls even when colleagues are audible in the background. Moreover, wear detection pauses music automatically when you remove an earbud to speak to someone, then resumes without requiring any button press.

Hi-Res Streaming on Android

Android users can enable LDAC in the Soundcore app to access high-bitrate wireless audio at up to 990 kbps. At this data rate, the 11mm drivers and extended 40 kHz frequency response become meaningful — instruments separate more clearly and high-frequency detail improves audibly on acoustic recordings and orchestral music. Note, however, that enabling LDAC disables multipoint connection for that session, so choose the mode that better suits your current use case.

Travel and Long-Haul Flights

The plane mode ANC profile adjusts cancellation for the low-frequency drone specific to cabin environments. Unlike a fixed ANC setting, it targets the pressure frequencies most prevalent at altitude. Furthermore, the case’s Qi wireless charging means the case can top up on a compatible pad in an airport lounge without needing to locate a USB-C wall socket. The 10-minute fast charge also provides a practical buffer when departure is imminent.

Considerations Before Buying

ANC performance is mid-tier, not flagship: Adaptive ANC 2.0 handles low-frequency drone and consistent mechanical sounds effectively. However, unpredictable sounds — voices, sharp impacts, variable crowd noise — break through more readily than on premium ANC earbuds. The Liberty 4 NC delivers strong value-per-pound for ANC, but it is not a direct substitute for the Liberty 4 Pro’s 7-sensor system or competing flagship models.

LDAC and multipoint are mutually exclusive: Enabling LDAC disables the dual-device connection feature. If you regularly switch between a phone and laptop, leaving LDAC off keeps multipoint available. iOS users cannot access LDAC in any configuration.

IPX4 covers sweat and splashes but not submersion: The earbuds handle rain and exercise sweat adequately. Nevertheless, they are not waterproof and should not be used swimming or submerged.

Ear tip variety is limited to four sizes: The Liberty 4 NC includes XS, S, M, and L ear tips only — not the six-size range (including XXS and XL) found on the Liberty 4 Pro. Listeners with unusually small or large ear canals may find fit more difficult to optimise, which also affects ANC seal performance.

No barometric sensor for flights: Unlike the Liberty 4 Pro, the Liberty 4 NC does not include a barometric pressure sensor. The plane transport mode adjusts the ANC curve, but it does not dynamically compensate for changing air pressure during ascent and descent.

Frequently Asked Questions

Does the Soundcore Liberty 4 NC Navy Blue differ in hardware from other Liberty 4 NC colours?

No. The Navy Blue variant (A3947Z31) is hardware-identical to Velvet Black, Pastel Pink, Light Blue, and Clear White variants. Drivers, battery, codecs, ANC system, and physical dimensions are all shared. Only the colour finish differs.

Is LDAC available on iPhone?

No. LDAC requires Android 8.0 or later. On iOS devices, the Liberty 4 NC connects via SBC or AAC. Both codecs deliver competent sound quality, but the hi-res wireless tier requires an Android device.

Does the charging case support wireless charging?

Yes. The Liberty 4 NC case charges via both USB-C and Qi wireless. Position the case at the centre of a compatible Qi charging pad for wireless top-up. Note that no wall charger or charging pad is included in the box.

Can I use one earbud at a time?

Yes. Either earbud works independently in single-earbud mode. Wear detection on the active earbud still functions, and calls auto-answer when you wear it. Place the unused earbud in the case to charge it while using the other.

What is the difference between the Liberty 4 NC and Liberty 4 Pro?

The Liberty 4 Pro adds a 7-sensor ANC system with a barometric pressure sensor for enhanced flight cancellation, dual-driver ACAA architecture (10.5mm + tweeter), an interactive Smart Display and touch bar on the charging case, faster 5-minute quick charge (vs 10 minutes), six ear tip sizes (vs four), and IPX5 water resistance (vs IPX4). The Liberty 4 NC offers wireless charging on the case — the Liberty 4 Pro does not. Both share LDAC, Bluetooth 5.3, and Adaptive ANC.

How do I activate LDAC?

Open the Soundcore app, navigate to the device settings for your Liberty 4 NC, and enable LDAC under the audio quality section. The app will notify you that LDAC disables multipoint connection. Switching codecs takes approximately 10 seconds, and a firmware update may be prompted if the earbuds are not running the latest version.
