Pro-Level Silence. Studio-Level Sound.

The Soundcore Liberty 4 Pro by Anker represents the pinnacle of wireless earbud engineering — 7-sensor noise cancellation that’s 3× stronger than standard ANC, studio-level ACAA acoustic architecture, super-fast 5C charging, and AI-enhanced call clarity with 6 microphones. For travellers, audiophiles, and professionals who refuse to compromise on sound or silence.

7-Sensor Matchless Noise Cancellation – 3× Stronger ANC

The Liberty 4 Pro features an industry-leading 7-sensor ANC system — 6 sound sensors and 1 barometric pressure sensor — capturing and cancelling noise from every angle simultaneously. The result is 3× stronger noise reduction than standard ANC earbuds, delivering a genuinely serene listening environment on planes, trains, busy offices, and crowded commutes.

Real-Time Adaptive Noise Reduction – Every 0.3 Seconds

Unlike fixed ANC systems, the Liberty 4 Pro’s adaptive noise reduction recalibrates every 0.3 seconds to match your ever-changing environment. Whether you move from a quiet room to a noisy street or board a flight mid-playlist, the ANC adjusts seamlessly — always optimal, always automatic, always on.

Studio-Level Hi-Fi Sound – ACAA Acoustic Architecture

Engineered with Anker’s enhanced ACAA acoustic architecture, featuring a 10.5mm bass driver, a titanium-coated tweeter, and a digital crossover for peak driver performance across the full frequency range. The result is crisp highs, rich mids, and deep, controlled bass — full-bodied, studio-quality sound with every nuance intact.

Super Fast Charging – 5 Minutes = 4 Hours

Powered by Anker’s 5C fast-charging battery — 2× faster than previous models. Just 5 minutes of charging delivers 4 hours of playtime. Enjoy up to 10 hours per charge on the earbuds alone, with the charging case extending total battery life to 40 hours. For travellers and commuters, this is the battery that never lets you down.

Effortless Touch Controls – Case Display & Touch Bar

Fine-tune your noise-cancelling levels directly from the case — a touch bar and display on the case let you adjust ANC settings with a simple swipe, without reaching for your phone. Intuitive, tactile, and designed for one-handed control on the move.

AI-Enhanced Calls – 6 Mics & Wind Noise Reduction

Six microphones combined with an AI noise reduction algorithm ensure your voice is transmitted with exceptional clarity on every call. A dedicated wind noise reduction algorithm filters out gusts and environmental interference — so whether you’re calling from a rooftop terrace or a busy street, the person on the other end hears you clearly.

Material

The earbud housing is crafted from premium glossy ABS plastic — smooth, durable, and refined in finish. The ear tips are made from soft medical-grade silicone in multiple sizes for a secure, comfortable in-ear seal that enhances passive noise isolation alongside the active ANC. The charging case features a precision hinge mechanism with a touch-sensitive display panel, engineered for thousands of open/close cycles. All materials are skin-safe and built for daily travel use.

7 sensors. 3× stronger silence. Studio sound. The earbuds that redefine what wireless audio can be.
