3× Stronger[1] Noise Reduction

Find your oasis of calm even in bustling city life and crowded flights. Six sound sensors, one barometric sensor, and a real-time algorithm ensure up to 3x stronger[1] noise cancellation.

[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.

[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.

Quiet Journeys, Regardless of Air Pressure

Enjoy up to 178% enhanced[5] noise cancelling during flights. A barometric sensor enables dynamic adjustments, creating a private, peaceful space despite air pressure shifts.

[5]Tests conducted in the soundcore lab show that Liberty 4 Pro can enhance noise cancellation by up to 5 dB for sounds below 300 Hz when air pressure is reduced by 24 kPa, which occurs when you are flying 1.24 miles above the ground. This results in a 178% improvement in noise- canceling performance.
