FAQ
The earbuds are on, but not connecting to my device
For the earbuds and your device to establish a connection, you need to put them both in pairing mode. Please follow the instructions in the “Pairing” section of this manual.
I’ve connected the earbuds with my smartphone but can’t hear any sound Double-check the volume level on your smartphone and the earbuds.
