• Disconnect other Bluetooth devices from your mobile: If you’ve already connected them to your mobile, then disconnect or remove them from the Bluetooth list. Then you can try these earbuds again on a device.
• Charge the Earbuds and Charging Case: It’s also worth recommending to keep charging your earbuds by placing them inside the charging case and then connecting the USB cable to the case and plugging the cable into a power source. Keep it charging for at least 30 minutes before checking for the connectivity issue again.
• Ensure both devices are compatible: It’s also possible that your earbuds aren’t compatible with the mobile or laptop due to the Bluetooth version. Although Bluetooth 5.2 is the latest one, and most of the next-gen Bluetooth devices do come with it, some other devices may have Bluetooth 4.0 or lower. In that scenario, you may experience Bluetooth connectivity issues or stability with the connection in some scenarios.

You can also check out the user manual guide for more clear information. (Note: You can repeat these steps if the reset was not successful or verify the results)

2. Hear Music only in One Earbud

The chances are high that somehow you’re able to hear music only in one earbud and the other one doesn’t offer you any sound at all.

• Reconnect the earbuds to each other: Sometimes the earbuds may cause such issues or you can say this is one of the main features. So, active noise-canceling earbuds offer individual connectivity with other devices simultaneously. You don’t need to disconnect or reconnect from the device every time if you’re using only one earbud. However, even if you’re not using an earbud individually, you may experience only one earbud working. So, try reconnecting the earbuds to each other. Just “Restart your earbuds by putting them into the charging case and closing the lid for around 10 seconds before trying again”.
  • If that doesn’t work for you, then place both earbuds in the charging case and then simultaneously press and hold the Left and Right buttons on the earbuds for 10 seconds until the LEDs on the earbuds flash purple > Close the lid of the charging case for 5 seconds to complete the reset process. Make sure to delete the previously paired device in the Bluetooth menu.
• Repair the earbuds: Try unpairing and pairing them again by putting them into the charging case. It’ll refresh the system.

3. Either the Right or Left Earbud is Not Working

There are possibilities to have issues with the right or left earbud not connecting in some cases. If you’re also facing the same issue then try performing the following steps below:

• Perform a Factory Reset: Make sure to do a factory reset as mentioned in the above methods. Then try reconnecting or re-pairing the left and right earbuds to a mobile device or a computer.
• Properly Charge Both Side Earbuds: Clean the charging pin/connector inside the case using a soft dry cloth and then return the earbuds. Then close the lid and charge the case to check whether both earbuds are charging.
• Ensure Both Earbuds Fits Well in the Charging Case: Make sure that both the left and right side earbuds are properly inserted inside the charging case, and that there is no issue with the charging pin/connector too.
• Use the Right Pairing Method: You’ll need to enter the pairing mode by pressing and holding the Left and Right buttons simultaneously on the earbuds for around 3 seconds until the LED on the right earbud flashes blue > Now, both the earbuds are ready to pair with your mobile device or computer.
