Use a Q-tip with a bit of rubbing alcohol to gently clean the metal mesh filter under the rubber ear tips.

If you need to adjust the volume, adjust both the software and the computer volume. The factory firmware of your earbuds does not include LDAC support. Therefore, it is necessary to update the firmware as per the provided guidelines. Try different types of music and turn up the volume on the connected device to see if it helps at all. When resetting the earbuds, make sure the earbuds are properly connected to the charging case, or it may cause the reset to fail.

Go to Settings > Sounds & Haptics > Headphone Safety and turn off Reduce Loud Sounds.If you make a call through an app, please try using your phone to make a call instead to see if the problem persists. Please note that this doesn't necessarily mean there is an issue with the earbuds but may have something to do with the connected device and environment. Bluetooth signals may be influenced by obstructions, such as walls, pillars, home appliances, Wi-Fi, and more. To ensure a stable connection, we recommend avoiding such obstructions. When the left earbud is in the charging case, the LED in the charging case is turned on. When the right earbud is in the charging case, the LED in the charging case is on.

How long does the Anker Soundcore Liberty 4 NC battery last?

Ensure that the audio output device selected is "Liberty 4 NC" on the connected device and turn up the volume on your device. Try testing your earbuds with a different Bluetooth device in a different environment to see if there is any difference. When the battery of the charging case is at 60-100%, all the lights will turn white for 5 seconds and then go out. Replace the earbud tips with ones that fit more snugly in your ears and ensure that you are wearing the earbuds in the correct position to create a tight seal. If the earbuds are not worn properly in your ears, you may not achieve the correct call performance.

It's important to note that there may be a slight delay when using Bluetooth headphones, which is a common limitation of Bluetooth technology. In most cases, this delay is minimal and should not impact your experience. However, it's worth mentioning that the delay can be influenced by various factors such as the Bluetooth headphones themselves, the connected device, the audio source, the specific application being used, and even the network conditions.
