Troubleshooting

Audio from earbuds is lagging or one side dropped out:

Possible Cause: Signal interference from surrounding environment (cellular signal tower, WIFI broadcast antenna).
Solution: Leave the premises to reduce interference.
Possible Cause: Earbuds are not properly connected or paired.
Solution: Turn off both earbuds, remove "TW100" from the Bluetooth device list on your mobile device, and re-initiate the pairing process.

Charging case cannot be recharged:

Possible Cause: A loose connection on the USB charging cable between the charging case and USB power source.
Solution: Check both connections of the USB charging cable.
Possible Cause: USB power source is not working.
Solution: Check the status of the USB power source.

Earbuds are not charging:

Possible Cause: Battery level in the charging case is low.
Solution: Connect the charging case with the included USB charging cable to a USB power source.
Possible Cause: Earbud charge points do not connect with charge points in the charging case.
Solution: Take out both earbuds and reposition them in the charging case until the red indicator light is on.

Earbuds cannot be paired with the mobile device:

Possible Cause: The pairing steps were missed.
Solution: Turn off both earbuds and go through the pairing steps again.
Possible Cause: Previously connected devices have not yet disconnected from the earbuds.
Solution: Check the Bluetooth setting on the previous connected device to either turn off the Bluetooth function or remove "TW100" from the list of devices.
Possible Cause: Battery level is low in earbuds.
Solution: Put both earbuds into the charging case to recharge (check the battery level in the charging case and connect to an external USB power source if necessary).
