Product Information

I was looking for a good pair of ear buds but didn't want to spend the money on my phone's brand or even a skull candy. Take the Fit Test on the soundcore app to check if you're wearing the earbuds in the perfect position. Find the most suitable ear tips for your ears, then check the bass to see if it has improved at all. Note: Battery playtime is obtained from testing in the Anker laboratory using the earbuds' default settings, in normal mode, and 50% volume. Use a Q-tip with a bit of rubbing alcohol to gently clean the metal mesh filter under the rubber ear tips.

Charge the charging case with a different charging cable and wall charger and make sure the charging case has enough power. Change the ear tips to ones that fit more snugly in your ears and make sure you're wearing the earbuds in the correct position to create a tight seal.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. 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. You will hear a pairing prompt tone, indicating that the earbuds have entered multipoint pairing status. I also like the feature that you can stop listening on your phone then open the iPad and it connects instantly.

Whenever I started talking while wearing these, I could feel the cancelling effect lift a little, allowing me to hear what I was saying without issue. If the indicators on the charging case don't light up, please check whether the charging case and earbuds are properly connected, have enough power, and you can clean the charging pins with a dry cloth. If the update fails, please try updating your firmware with a different Bluetooth device in a good network environment to see if it helps at all.If the indicators in the charging case don't light up, please check whether the charging case and earbuds are properly connected, have enough power, and clean the charging pins with a dry cloth. Bluetooth signals may be influenced by obstructions, such as walls, pillars, home appliances, Wi-Fi, and more. Access the Bluetooth settings on one device and disconnect the earbuds from the list of available devices.

The earbuds keep connecting to the device even after being put back in the charging case with the cover closed. If one of your earbuds doesn't fit well, please try a combination of the ear tips, such as medium in the left and large in the right. Overall not as good as the 2s but I’ve lost them now so will hope that XXL tips become available for the 4. Try different types of music and turn up the volume on the connected device to see if it helps at all.The battery is good, it lasts a long time, the noise quality is great and it let's you pick pre-set sound or customised. 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 still can't connect using the steps above, provide the mobile phone model, app version, screenshots in Step 5, mobile phone system region, and language settings. If there is a pop-up window to confirm pairing for "soundcore Liberty 4 NC," please select "pair" If you accidentally select "cancel" you need to refresh (turn off and turn on) the Bluetooth of your device and pair the earbuds again. To ensure a successful reset, make sure that the left and right earbuds are placed correctly inside the charging case, and you should see white LED indicators, indicating a proper connection.

In LDAC mode, high-speed transmission leads to increased power consumption, and it is normal for power consumption to increase. When the charging case is fully charged, all the white lights will stay on for 5 minutes and then go out. 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.

When the battery of the charging case is at 60-100%, all the lights will turn white for 5 seconds and then go out.
