1. Based on tests conducted in the Soundcore lab, Liberty 4 Pro can reduce up to 12.2 dB more noise in 600-200Hz 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 ANG 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 3x more data compared with standard, with the bitrate of 328kbps.
You can turn on LDAC mode in the Soundcore app. LDAC is only compatible with Android device DAC 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.
