Clean the charging pins using a dry cloth to remove any dirt or debris that may hinder the charging process. If the earbuds are not worn properly in your ears, you may not experience the best noise cancellation.

If one earbud feels stable and the other does not, try a combination of ear tips such as medium in the left and large in the right. Ensure that the ear tips are not blocking the charging pins on the earbuds and in the charging case.When the battery of the charging case is at 0-20%, the light in the middle of the charging case will turn red for 5 seconds and then go out. If you only want to listen to the audio on the computer, select "soundcore Liberty 4 NC Stereo" for the computer audio. To check if you're wearing the earbuds in the perfect position, take the Fit Test on the soundcore app or check the Quick Start Guide for more information.

I have only used these on my commute and on my daily walk and I haven't used them when running or high movement so I can't say if they're good at staying in the ear no matter what, but for what I need then they've been great.In LDAC mode, high-speed transmission leads to increased power consumption, and it is normal for power consumption to increase. Make sure the charging case has enough power, and the ear tips are not blocking the charging pins on the earbuds. Test your earbuds with a different Bluetooth device, app and downloaded music/video to see if the problem still persists. Look at the L/R logo on the back of the earbuds to ensure that the left and right earbuds are being worn on the correct sides.
