Losei support FAQ

Common questions about manuals, registration, and support for this brand.

  • How do I reset my Losei earbuds?

    Place both earbuds into the charging case and ensure they are charging. Touch and hold the sensor area on both earbuds for about 8 seconds until the indicator lights flash. Take them out of the case to automatically pair them again.

  • What should I do if my Losei earbuds stop charging?

    First, make sure to remove the plastic protective film on the earbuds' charging contacts. Also, ensure the charging case is fully charged and that the charging pins are clean and dry.

  • Why does the sound cut in and out on my Losei earbuds?

    Make sure there are no physical obstacles between the earbuds and your device. Avoid being near microwave ovens or Wi-Fi transmitters, as these can cause electromagnetic interference and dropouts.

  • Can I use just one Losei earbud at a time?

    Yes, Losei earbuds typically support a single mode. Simply take either the left or right earbud out of the charging case, then search for and connect to the corresponding designated single earbud name in your device's Bluetooth menu.
