GENERAL TIPS FOR TRUE WIRELESS EARBUDS

• Hold the earbud stem when putting or adjusting the earbuds in your ears. This way you avoid touching the sensitive touch area which control different functions.
• The volume effects the capacity of the battery. If you play your music with lower volume, you will increase battery life.
