Anker Soundcore Liberty 4 Pro

Innovative Smart Case with Display & Touch Bar: Experience a revolutionary approach to earbud interaction. The Liberty 4 Pro features an advanced charging case integrated with a built-in Smart Display and physical Touch Bar. Without opening your phone or launching an app, you can instantly read real-time battery percentages, monitor charging speeds, and adjust your active noise cancellation or ambient transparency depth with a simple slide of your finger across the case.

7-Sensor Advanced Adaptive ANC 3.0 Architecture: Immerse yourself in absolute tranquility. The earbuds are armed with an industry-leading 7-sensor tracking grid—consisting of 6 sound-sampling microphones and 1 integrated barometric pressure sensor. Operating via a real-time algorithm that recalculates every 0.3 seconds, it delivers up to 3× stronger noise reduction. The barometric sensor automatically registers atmospheric pressure shifts to optimize acoustic dampening during high-altitude flights.

ACAA 4.0 Coaxial Dual-Unit Speaker System: Indulge in breathtaking studio-grade high-fidelity audio. The upgraded Astria Coaxial Acoustic Architecture (ACAA 4.0) pairs a massive 10.5mm low-frequency bass driver with a highly responsive 4.5mm titanium-coated tweeter on a single axis. Driven by an internal digital crossover network, this setup delivers deep, chest-thumping bass and pristine high-frequency vocal separation across a wide 14Hz to 40kHz range.

Hi-Res Wireless Sound with LDAC Decoding: Experience digital audio with zero acoustic compromises. Certified with official Hi-Res Audio Wireless, the earbuds natively support the high-bandwidth LDAC audio codec. When paired with compatible Android smartphones, it transmits up to three times more data over the air than standard Bluetooth methods, reproducing every fine nuance of a live master recording.

360° Immersive Spatial Audio with Dynamic Head Tracking: Step completely inside your favorite entertainment layouts. Using built-in high-precision gyroscopes and spatial computing cores, the earbuds track your subtle head movements in real-time. This continuously shifts the acoustic soundstage to keep you positioned dead-center inside movies, spatial music tracks, and high-speed mobile gaming environments.

Ultra-Fast 5C Charging with 40-Hour Total Matrix: Cut down your charging downtime drastically. Utilizing an upgraded 5C fast-charging battery cell configuration, these earbuds refuel up to two times faster than previous generations. A blistering 5-minute emergency charge inside the case yields 4 full hours of playback. On a full charge, enjoy up to 10 hours of standalone runtime (6.5 hours with ANC on), reaching a massive 40 hours of total power via the sliding-lid charging case.

6-Mic AI Clear Calls with Intelligent EasyChat: Maintain crystal-clear vocal projection during remote business meetings and windy outdoor commutes. The 6-microphone array works alongside an AI-driven environment noise isolation algorithm to strip away background traffic noise and heavy wind gusts. Furthermore, activating EasyChat Mode automatically detects when you speak, instantly lowering your music volume and switching to transparency mode for effortless face-to-face conversations.

Premium Ergonomic Streamline Fit with 6 Tip Sizes: Designed for secure, pressure-free wear during extensive production hours. The sleek white earbud shells enter the ear canal at a natural 30-degree incline, maintaining a lightweight 5.5g weight footprint per side. To guarantee a perfect acoustic seal for any ear anatomy, the package includes 6 distinct sizes of soft silicone ear tips (XXS, XS, S, M, L, XL).

IPX5 Splash-Proof and Sweat-Resistant Protection: Push through intense workout routines or sudden outdoor weather shifts with complete confidence. The earbud structures are sealed with an official IPX5 weather-proof defense rating, fully safeguarding the delicate internal audio drivers and biosensors from heavy gym sweat, splashes, and unexpected rain.

Bluetooth 5.3 & Multi-Device Multipoint Connectivity: Enjoy an energy-efficient wireless experience free from dropouts. Powered by Bluetooth 5.3 technology, the earbuds feature built-in Multipoint Connection capability. This lets you seamlessly pair and switch between two source devices concurrently—letting you answer an urgent call on your smartphone while watching a video on your laptop.
