The Soundcore Liberty 4 NC represents a strategic balance between advanced features and accessible pricing within Anker’s wireless earbud lineup. These true wireless earbuds integrate Adaptive Active Noise Cancelling (ANC 2.0) technology capable of reducing up to 98.5% of ambient noise through a combination of internal and external sensors.
What sets them apart in their price category is support for Hi-Res Wireless audio via LDAC codec, enabling higher-quality streaming than standard Bluetooth alternatives.
The combination of effective noise cancellation, extended battery performance, and app-driven sound customization positions these earbuds as a practical choice for users seeking premium functionality at mid-range costs.
Key Features
Core Capabilities
The Liberty 4 NC’s standout feature is its Adaptive ANC 2.0 system, which automatically adjusts noise cancellation intensity based on your ear shape and the surrounding acoustic environment. Rather than applying uniform noise reduction, this intelligent approach tailors performance in real time.
Sound Engineering
Dual technologies drive the audio experience. The 11mm custom dynamic drivers deliver detailed sound with pronounced bass and balanced treble throughout the frequency range.
LDAC support enables higher-bandwidth audio streaming, while standard AAC and SBC codecs provide compatibility across devices. The Soundcore companion app includes HearID sound personalization and multiple EQ presets, allowing you to fine-tune the audio signature to match your preferences.
Connectivity & Hands-Free Features
Multipoint Bluetooth connectivity permits simultaneous pairing with multiple devices, streamlining transitions between your phone, tablet, and computer. A six-microphone AI call system works with environmental noise suppression to enhance voice clarity during phone conversations. The charging case supports both USB-C wired charging and Qi wireless charging for added convenience.
Audio Performance
The earbuds employ a bass-forward sound signature with clear midrange and balanced treble that adapts through customizable EQ presets. The 11mm dynamic drivers handle both detailed instrumental work and vocal-focused content effectively. Support for LDAC, AAC, and SBC codecs ensures compatibility while LDAC streaming provides certified Hi-Res Audio Wireless performance for compatible devices.
Noise Cancellation
Adaptive ANC 2.0 stands as the primary noise management tool, delivering up to 98.5% environmental noise reduction. Three listening modes accommodate different scenarios: adaptive ANC automatically adjusts based on conditions, manual ANC levels let you select specific reduction intensities, and transparency/ambient mode allows external sound when needed.
Battery & Charging
The earbuds provide up to 10 hours of playback with ANC disabled, though enabling ANC reduces this to approximately 8 hours depending on usage patterns and volume levels. Combined with the charging case, total battery capacity reaches up to 50 hours. Fast charging delivers several hours of playback from a brief charge session, while both USB-C and Qi wireless charging options eliminate dependency on wired connections.
Connectivity
Bluetooth 5.3 powers the wireless connection with multipoint support enabling seamless device switching. The Soundcore app facilitates firmware updates, EQ customization, and HearID personalization to refine your listening experience across different music genres and content types.
Microphones & Call Quality
The six-microphone array with AI noise reduction targets voice enhancement and environmental noise suppression during calls. This setup aims to preserve your voice clarity while minimizing background interference, though the microphone performance sits at average levels compared to premium flagship alternatives.
Design & Build
These in-ear earbuds feature a stem design with IPX4 splash and sweat resistance suitable for workouts and commuting. The package includes multiple silicone ear tip sizes (XS, S, M, L) to accommodate different ear geometries. Touch controls integrate customizable gestures through the Soundcore app, letting you tailor button functions to your needs.
Physical Specifications
Each earbud weighs approximately 10 grams as a pair, while the charging case weighs 48.6 grams. This lightweight construction minimizes fatigue during extended wear sessions.
Available Colors
The Liberty 4 NC comes in five color options: Black, White, Blue, Navy, and Pink, offering visual choices to match personal style preferences.
Advantages & Limitations
Strengths
Exceptional battery endurance relative to the price point stands out immediately. The Adaptive ANC 2.0 system delivers competitive noise cancellation performance. LDAC Hi-Res audio support remains uncommon at this price tier, while the Soundcore app provides extensive sound customization options rarely found in similarly priced models.
Tradeoffs
The microphone system performs adequately but lacks the refinement of premium flagship earbuds. Some users may experience a slightly loose fit depending on individual ear anatomy, requiring experimentation with the included tip sizes to achieve optimal security.
Summary
The Soundcore Liberty 4 NC delivers strong practical value by combining adaptive noise cancellation, LDAC Hi-Res wireless audio, battery life extending to 50 hours with the case, and comprehensive sound customization through the Soundcore mobile app.
These capabilities address everyday listening needs for commuting, travel, and daily use while offering features typically associated with significantly higher price points.
