Depending on the other music app you are using (other than the Music Player), the (play/pause) button on the unit may not be enabled correctly.
If this is the case, the music you hear may overlap, since the Music Player and the other app may both start when press the (play/pause) button.
Follow these steps to play music using an app other than the Music Player:
- Press the (play/pause) button on the unit, then pause the music that has been played overlapping.
- Play or pause the running player app by operating on the app screen.
