Press twice within 5 seconds of a new track to replay the previous track. Press twice after the 5 seconds will bring the song to the begnining of the current track. Press three times, and you will go to the next track. When you start to speak, the volume will lower, and you will be able to hear what the person might be saying.

All earphones will come with a case, and that case will charge the earphones. You can see the percentage by tapping the screen, and you would charge up to 30 watts with USB.
