Description

The Ultimate Noise Cancellation System

The Liberty 4 Pro ushers in a new standard for quiet, engineered with a total of seven sensors. This includes six sound sensors and a barometric pressure sensor, which work in harmony to capture and neutralize unwanted noise from every angle. This sophisticated system allows for 3x stronger noise reduction, transforming your daily commute or flight into a serene personal oasis.

This power is driven by Adaptive ANC 3.0, an intelligent algorithm that performs millions of calculations per second. It recalibrates the noise-cancelling curve every 0.3 seconds to adapt to your ever-changing surroundings in real-time, ensuring you always have the optimal level of quiet, whether you’re on a busy street or in a quiet office.

Studio-Level High-Fidelity Music

Inside each earbud lies Soundcore’s latest acoustic achievement, ACAA 4.0 (Coaxial Acoustic Architecture). This system pairs a powerful 10.5mm woofer with a dedicated 4.6mm titanium-coated tweeter in a coaxial design. A digital crossover ensures each driver performs at its peak, delivering a rich, balanced soundstage with deep, punchy bass and crisp, extended treble.

For Android users, support for the LDAC™ audio codec and Hi-Res Audio Wireless certification means you can stream high-resolution music with exceptional clarity and detail, preserving the artist’s true intent. You can also immerse yourself in 360° Spatial Audio with head tracking, which dynamically adjusts the soundscape as you move your head for a truly captivating, concert-like experience.

Revolutionary Smart Charging Case

The Liberty 4 Pro introduces a game-changing feature: a smart charging case with an integrated OLED display and touch bar. This innovative case allows you to interact with your earbuds without ever touching your phone. The built-in screen lets you quickly check the battery status of both the earbuds and the case at a glance. With a simple swipe on the touch bar, you can effortlessly adjust the noise cancellation or transparency levels, putting intuitive control right at your fingertips.

Note: On the White model, the case has a stylish matte, opaque finish, requiring you to open the lid to view the display.

Flawless Communication

Never let a noisy environment get in the way of a clear conversation. The Liberty 4 Pro is equipped with a sophisticated 6-microphone array. These mics work with advanced AI noise-reduction algorithms to filter out background noise, from howling wind to the chatter of a crowded train. A dedicated wind noise reduction algorithm ensures your voice is transmitted with perfect clarity on every call, no matter the weather.

Rapid Charging and All-Day Power

With 5C fast charging technology, the Liberty 4 Pro is designed to keep up with your busy life. A mere 5-minute charge provides a full 4 hours of playback, so you’re never without your music for long. On a single charge, the earbuds themselves offer up to 10 hours of continuous playtime. With the pocket-friendly charging case, you can enjoy a total of up to 40 hours of listening before needing to find a power outlet. The case also supports convenient Qi wireless charging.

Seamless Connectivity

Built with Bluetooth 5.3, the Liberty 4 Pro ensures a stable, high-quality connection with minimal dropouts. The multipoint connection feature allows you to seamlessly switch between two devices, such as your laptop and smartphone. Google Fast Pair enables an instant and effortless connection with your Android devices.

Customizable Comfort and Durability

Your comfort is paramount. The earbuds come with six different sizes of ear tips (XXS, XS, S, M, L, XL) to ensure a perfect, noise-isolating seal for all-day wear. With an IPX5 water-resistance rating, they are protected against sweat and light rain, making them the perfect companion for workouts and outdoor activities.
