Upgrade your listening experience with the Anker Soundcore Liberty 4 Pro Noise Cancelling True Wireless Earbuds. Designed for music lovers, commuters, and professionals, these premium earbuds combine Adaptive ANC 3.0, a dual dynamic driver system, personalised audio settings, and a smart charging case with an integrated touch bar and display.
Enjoy detailed sound, immersive listening, convenient controls, and clearer conversations with six microphones and AI-enhanced call processing. With Bluetooth 5.3, multipoint connectivity, and fast charging, the Liberty 4 Pro is built for everyday entertainment and productivity.
Enjoy a more focused listening experience with Adaptive Active Noise Cancelling 3.0. Six sound sensors and one barometric pressure sensor work with an adaptive algorithm to detect environmental noise and adjust noise cancellation in response to changing surroundings.
Soundcore states that the system recalibrates every 0.3 seconds. Whether you are commuting, working in a busy environment, or relaxing with music, the adaptive system is designed to help minimise distractions. Actual noise reduction depends on the environment and fit of the earbuds.
The Liberty 4 Pro features a dual dynamic driver system consisting of a 10.5 mm driver and a 4.6 mm driver. The combination is designed to reproduce powerful bass, clear vocals, and detailed high frequencies.
Its ACAA acoustic system and digital crossover help the two drivers work together for a balanced listening experience. Support for Hi-Res Audio Wireless and LDAC provides compatible devices and audio sources with the option to stream higher-resolution wireless audio.
For personalised listening, use the Soundcore app's supported sound customisation features, including HearID 4.0 and adjustable EQ settings.
The charging case adds more than battery storage. Its built-in display and touch bar let you adjust supported noise-cancelling settings directly from the case, reducing the need to open the mobile app for every adjustment.
This practical design brings key controls into one compact accessory and makes it easier to fine-tune your listening experience on the go.
Stay connected during work calls, online meetings, and everyday conversations. Six microphones work with AI-assisted noise processing and wind-noise reduction technology to help improve voice clarity in different environments.
Call quality can vary depending on surrounding noise, network conditions, microphone placement, and the device connected to the earbuds.
Listen for longer with up to 10 hours of playback on a single charge and up to 40 hours with the charging case when ANC is off. With ANC enabled, the stated figures are up to 7.5 hours on a single charge and up to 30 hours with the case.
Need a quick power boost? A five-minute charge can provide up to four hours of playback under Soundcore's specified test conditions. Actual battery life varies with volume, audio content, ANC settings, calls, and other usage conditions.
Bluetooth 5.3 provides wireless connectivity to compatible devices. Multipoint support allows the earbuds to connect to two devices simultaneously, making it convenient to switch between tasks such as listening to music on a laptop and answering a call from a phone.
Available audio codecs and features depend on the connected device, operating system, and selected settings.
The official Soundcore product page lists an IPX5 water-resistance rating for the earbuds. This rating is intended for resistance to water jets under specified test conditions; it does not mean the earbuds are waterproof or suitable for submersion. Avoid charging wet earbuds or case components.
