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.
