GENERAL TIPS

• Because of interference with other Bluetooth devices, the earbuds can get disconnected from each other. If you experience this problem, put the earbuds in the charging case and close the cap. After a few
  seconds, open the cap and start using the earbuds.

• Hold the earbud stem when putting or adjusting the earbuds in your ears. This way you avoid touching the touch area which controls different functions.

• The volume affects the capacity of the battery. If you play your music with lower volume, the battery life will last longer.

• Pause between each touch control command, e.g. wait 1 second between each volume control tap to further increase/decrease volume.
