FAQ

• How long does it take to fully charge the earbuds?
It takes around 1.5 hours to fully charge the earbuds.


• How long does it take to fully charge the charging case?
It takes around 3 hours to fully charge the charging case via a wall charger; 3.5 hours via a wireless charger.


• What should I do if one side is discharging quickly?

Normally, the earbuds can be used for around 8 hours in ANC mode and 10 hours in Normal mode at 50% volume, but playtime may vary slightly based on the music content and volume. If you use the earbuds to make/receive calls, playtime will be shorter as it consumes more power than playing music.

Try the following steps to troubleshoot this problem:

1. Ensure the protective film has been removed from the earbuds.
2. Use a dry cloth/cotton swab with rubbing alcohol to clean the charging pins in the charging case and on the earbuds to ensure a better connection. Ensure the ear tips are not blocking the charging connectors and fully charge your earbuds.
3. Charge the charging case with a different charging cable and wall charger and make sure the charging case has enough power. When the indicators turn off, the charging case is fully charged.
4. Test the battery when playing music.

ANC is turned on by default. If you want to test the playtime in Normal mode, switch to Normal mode first.


• What is Liberty 4 NC's playtime from a single charge/with the charging case?

Normal: 10 hours of playtime for earbuds and 50 hours for the charging case.
ANC: 8 hours of playtime for earbuds and 40 hours for the charging case.
Transparency: 8 hours of playtime for earbuds and 40 hours for the charging case.
LDAC and ANC Mode: 5 hours of playtime for earbuds and 25 hours for the charging case.
LDAC On (ANC Off): 6 hours of playtime for earbuds and 30 hours for the charging case.
Calls (ANC Off): 4.5 hours of use.
Calls (ANC On): 4 hours of use.

Note: Battery playtime is obtained from testing in the Anker laboratory using the earbuds' default settings, in normal mode, and 50% volume. The actual playtime may vary by volume, audio source, environmental interference, usage, etc.


• What should I do if any of the following problems occur? 1) The earbuds don’t recharge in the charging case. 2) The earbuds keep connecting to the device even after being put back in the charging case with the cover closed. 3) The earbuds don't turn on when taken out of the charging case.

1. Remove the protective film covering the charging pins on the earbuds.
2. Ensure that the ear tips are not blocking the charging pins on the earbuds and in the charging case. Make sure that the earbuds are connected to the charging case. If you place the left and right earbuds in the charging case and the LED indicators on the charging case flash white, it means they are connected properly.
3. 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.
4. Charge your charging case with a different charging cable and wall charger, and make sure the charging case has enough power.

If your earbuds haven't been used for a long time, please make sure you charge them for at least 2 hours to see if it helps at all.
