Product Information

Find the most suitable ear tips for your ears, then check the bass to see if it has improved at all. Press and hold the charging case button for 10 seconds until the LED indicators in the charging case flash white rapidly three times.

Note: Battery playtime is obtained from testing in the Anker laboratory using the earbuds' default settings, in normal mode, and 50% volume. I like to listen to music or podcasts wherever I go, but I rarely have an ideal listening environment. If you are using a Samsung mobile phone, you may need to manually activate the LDAC switch in the Bluetooth settings interface.Use a dry cloth or cotton swab with a bit of rubbing alcohol to clean the charging pins in the charging case and on the earbuds to ensure a better connection. Use a Q-tip with a bit of rubbing alcohol to gently clean the metal mesh filter under the rubber ear tips.

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 you can also clean the charging pins with a dry cloth. Unfortunately none of them XXL so the tip test still reveals a poor seal and when exercising they occasionally fall out. Charge the charging case with a different charging cable and wall charger and make sure the charging case has enough power.

If you only want to listen to the audio on the computer, select "soundcore Liberty 4 NC Stereo" for the computer audio. Try different sizes of ear tips and make sure you're wearing the earbuds in the correct position so that they create a tight seal. Ensure that the ear tips are not blocking the charging pins on the earbuds and in the charging case.

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. 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. I also like the feature that you can stop listening on your phone then open the iPad and it connects instantly. Noisy environments get an extra layer of dampening, so even when I was exercising with equipment at a very busy gym, nothing was distracting me from my playlist.That's a pretty big claim to make, so naturally, we're curious to see if it can live up to those high expectations. 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. When resetting the earbuds, make sure the earbuds are well connected with the charging case, or it may cause the reset to fail. In LDAC mode, high-speed transmission leads to increased power consumption, and it is normal for power consumption to increase.

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. After the update is completed, you will notice an LDAC icon on the Liberty 4 NC interface in the soundcore app. If the problem still persists, please provide your phone model and the Serial Number on the app so our team can investigate further. 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.When you place the left and right earbuds in the charging case, there will be white LED indicators that confirm the earbuds are properly connected to the charging case. 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. Soundcore has a variety of high-quality headphones and earbuds, and the Liberty 4 NC is a great demonstration of that. Replace the ear 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.
