Liberty 4 Pro
7-Sensor Precise Noise Cancelling

1. Based on tests conducted in the soundcore lab, Liberty 4 Pro can reduce up to 12.2 dB more noise in the 600-700Hz range when tested from the opposite side of the earbud. This improvement is three times more effective than with the adaptive noise cancelling algorithm turned off. | 2. Calculated based on the recalibration frequency of the ANC algorithm, which is three times per second when no audio is being played. | 3. It charges twice as fast as Liberty 4 NC. | 4. LDAC enables the transmission of audio content at the maximum bitrate of 990kbps, which transmits 3× more data compared with standard SBC codec with the bitrate of 328kbps.

You can turn on LDAC mode in the soundcore app. LDAC is only compatible with Android devices. | LDAC and LDAC logo are trademarks of Sony Corporation. | Hi-Res Audio logo and Hi-Res Audio Wireless logo are registered trademarks or otherwise trademarks of Japan Audio Society.

How to use

Charge the earbuds and case via the USB Type-C port before first use. Open the case and remove the earbuds to power them on and initiate Bluetooth pairing; follow device prompts to complete pairing with your phone or player. Fit each earbud into the ear canal for secure intraaural coupling and adjust by testing fit and seal. Use the touch-sensitive controls on the earbuds and the touch bar on the case to change noise-cancelling levels, control playback and answer calls. For LDAC or additional settings, install and use the manufacturer’s companion app on compatible devices.

Recommendations

Select an ear tip size that provides a proper seal to maximise passive isolation and ANC performance. Use fast charging for short top-ups when time is limited and fully charge the case regularly to preserve overall battery availability. Enable LDAC in the companion app only on compatible Android devices when higher wireless audio bitrate is required. Clean earbud contact points and ear tips periodically and avoid exposing the charging case to extreme temperatures or moisture.
