Some Common Problems & Troubleshooting

Left/Right/One side of the earbuds has stopped working

If this happens, it may be because it is low on battery or it did not connect correctly with the device. To fix this, you can do the following:

1. Try charging the earbud that is not working or both, placing them in the charging case.

2. Try factory resetting the earbuds.

3. Check if the earbuds are operating within a normal working range.

If that doesn’t work, the earbud is probably faulty, and I can go for a refund or replacement of it.

Left/Right/One side of the earbuds has a low volume

1. Try cleaning the earbud using a cotton swab or carefully clean the mesh with a pin.

2. Try factory resetting the earbuds.

The microphone is not working

If this happens, it can be because the microphone is muted, or the earbuds are badly positioned. To fix this, you can do the following:

If the microphone is muted, check the device microphone volume. If that doesn’t work, that means that there might be a defect in the earbuds, so try replacing them or getting a refund.
