Soundcore Liberty 4 NC True Wireless ANC Earbuds – Black

Soundcore Liberty 4 NC Kuwait delivers powerful adaptive noise cancellation, detailed Hi-Res wireless sound, long battery life, and intelligent personalization in a compact pair of true wireless earbuds. Featuring Adaptive ANC 2.0, up to 98.5% noise reduction, custom-tuned 11mm dynamic drivers, LDAC, HearID 2.0, Bluetooth 5.3 multipoint connectivity, six microphones with AI-enhanced calls, wireless charging, and up to 50 hours of total playtime, Liberty 4 NC is designed for commuting, travel, work, calls, workouts, and everyday listening.

Adaptive ANC 2.0 Noise Cancellation

One of the main features of Soundcore Liberty 4 NC is its Adaptive ANC 2.0 system.

Instead of using one fixed level of active noise cancellation, the earbuds analyze both the surrounding environment and the user’s ear canal in real time. Soundcore says this adaptive system can reduce external noise by up to 98.5%, with the noise-reduction performance tested by SGS.

This makes the earbuds particularly useful in environments such as:

• Airplanes
• Busy streets
• Offices
• Shopping malls
• Public transport
• Cafés
• Daily commutes

The amount of noise reduction achieved in real use can vary depending on ear-tip fit, environment, and frequency of the surrounding noise.

Custom-Tuned 11mm Dynamic Drivers

The Soundcore Liberty 4 NC Kuwait uses large 11mm custom-tuned dynamic drivers designed to produce clear detail and strong low-frequency performance.

Soundcore combines the drivers with a dedicated noise-isolation chamber to reduce distortion and improve both music reproduction and active noise cancellation performance.

The earbuds are suitable for a wide range of music styles, podcasts, movies, and general daily listening.

Hi-Res Wireless Audio

Liberty 4 NC supports Hi-Res Wireless Audio, giving compatible devices access to higher-quality wireless playback.

The earbuds also support LDAC, a high-resolution Bluetooth audio codec capable of transferring up to three times more data than standard SBC under supported conditions. Soundcore specifies an LDAC maximum bitrate of up to 990kbps compared with 328kbps for standard SBC.

Supported codecs include:

SBC / AAC / LDAC.

LDAC availability depends on the connected device and must be enabled through the Soundcore app where supported. Soundcore notes that LDAC is compatible with Android devices.

HearID 2.0 Personalized Sound

Not everyone hears music in exactly the same way.

The Soundcore app includes HearID 2.0, which can create a personalized sound profile based on your listening preferences.

Users can also manually customize the EQ or choose from 22 preset EQ profiles.

This gives users more control over bass, vocals, treble, and overall sound balance than earbuds with a fixed audio profile.

Up to 10 Hours Playtime

With active noise cancellation turned off, the earbuds provide up to:

10 hours of playtime from the earbuds

and:

Up to 50 hours total with the charging case.

With ANC enabled, Soundcore lists:

Up to 8 hours from the earbuds
Up to 40 hours total with the charging case.

Actual battery life varies according to volume, ANC, LDAC, calls, operating conditions, and other settings.

Fast Charging: 10 Minutes for 4 Hours

If the battery is low before leaving home, Liberty 4 NC supports fast charging.

Soundcore specifies:

10 minutes of charging = up to 4 hours of playtime.

This is especially useful for commuters and travelers who need a quick battery boost.

USB-C & Wireless Case Charging

The charging case supports:

• USB-C charging
• Wireless charging

Soundcore’s technical specification lists approximately:

Earbuds charging time: 1 hour
Case via USB-C: 3 hours
Case via wireless charger: 3.5 hours.

Wireless charging makes it possible to place the case on a compatible Qi charging pad without connecting a cable.

6 Microphones with AI for Calls

The earbuds incorporate six microphones combined with an AI algorithm to improve voice clarity during calls.

The system is designed to reduce unwanted uplink/background noise so your voice can be heard more clearly in compatible calling environments.

This makes the Liberty 4 NC useful for:

• Phone calls
• Online meetings
• Voice chats
• Work calls
• Video conferencing

Bluetooth 5.3

The Soundcore Liberty 4 NC Kuwait uses Bluetooth 5.3.

The official specification lists a Bluetooth range of approximately:

10 meters / 33 feet under suitable conditions.

Walls, interference, and other environmental factors can reduce real-world range.

Multipoint Connection

Liberty 4 NC supports multipoint Bluetooth connectivity, allowing the earbuds to connect to two compatible devices at the same time.

For example, you could stay connected to:

Laptop + smartphone

and switch between media or calls without repeatedly disconnecting and re-pairing the earbuds.

Fast Pair

Soundcore also supports quick Bluetooth pairing with compatible Android devices.

This helps simplify initial setup and reconnection when used with supported phones.

Auto Play & Pause

The Liberty 4 NC includes wear detection for automatic playback control.

Removing an earbud can pause compatible playback, and putting it back in can resume listening.

This makes everyday listening more convenient when someone speaks to you or when you temporarily remove the earbuds.

IPX4 Water Resistance

The earbuds carry an IPX4 water-resistance rating.

This provides resistance against splashes, sweat, and light rain within the limits of the IPX4 rating.

They can therefore be suitable for:

• Gym use
• Walking
• Running
• Daily commuting

However, they should not be treated as waterproof swimming earbuds.

The IPX4 rating applies to the earbuds, not necessarily the charging case.

Lightweight In-Ear Design

Each earbud weighs approximately:

5–5.2g

without the charging case.

The compact in-ear design helps make them comfortable for extended music listening, commuting, and calls when the correct ear-tip size is selected.

Touch Controls

The earbuds use touch controls, allowing compatible functions to be controlled directly from the earbuds without always reaching for your phone.

Available controls can be customized through the Soundcore app depending on firmware and app settings.

Frequency Response

Soundcore’s technical documentation lists a frequency response of:

20Hz–40kHz.

Combined with LDAC and Hi-Res Wireless support, this gives the earbuds a strong specification for customers looking for higher-quality wireless music playback.
