Frequently Asked Questions

  • What is the best way to tell if your Bluetooth earphones are completely charged?
    When the battery is charging, the indicator light will turn on. The light may take up to one minute to turn on. 3. The indicator light will turn off when the headset’s battery is fully charged (approximately 2-3 hours).
  • How do I convert my Chinese earbuds to English?
    Put one earbud in each ear and turn it on. 3. After you hear the first earbud “talk,” wait for the second one to “speak,” then double-click it and it will say “English.” Both of these documents should now be in English.
  • What is the best way to see if my earbuds are charging?
    The light indicates the charge status of your AirPods if they are in your case and the lid is open. The light indicates the status of your case when your AirPods aren’t in it. Green indicates that the battery is completely charged, while amber indicates that less than one full charge remains.
  • How long does it take to charge earbuds?
    The earphones take around 2 hours to fully charge. If the battery is low, charging it in the charging case for 10 to 20 minutes can give you an extra hour of use. Connect the charging case to a USB power source or an approved wall charger.
  • How long does it take to charge Bluetooth earbuds?
    Bluetooth headphones have 22-hour battery life and take two to three hours to fully charge. The average Bluetooth earphone charges between one and a half to two hours. The earphones have a battery life of 5 hours and the charging case has a battery life of 24 hours.
  • Why are my Bluetooth earbuds only working on one side?
    Depending on your audio settings, headphones may only play in one ear. Check your audio properties to make sure the mono option is disabled. Also, make sure that the voice levels on both earphones are equal.
  • Why aren’t my Bluetooth earbuds communicating with one another?
    Turn off your device’s Bluetooth option. Remove the earbuds from the casing and they will automatically turn on. To manually sync the left and right earbuds, double-press both of them at the same time. NOTE: Try it again if it doesn’t work the first time.
  • Why aren’t my earbuds working together?
    Step 1: To reset the headphones, double-press the power keys on both sides while the headphones are charging (the white LED indication on the earphones is on). Remove both headphones from the charging case, and they will automatically turn on and connect within 60 seconds.
  • On Bluetooth headphones, where is the power button?
    You’re referring to the middle of the “three.” It’s fantastic because everything is on the same side. If you want to connect to your phone, the center button also serves as a “answer and hang-up” button.
  • What happens if one of the earbuds fails?
    If a single earbud only cuts out every now and again, try twisting and taping the cable until sound returns. If twisting the wire doesn’t work, you may need to open the earbud and, if possible, solder the connection. You may need to purchase new earbuds in some circumstances.
