There are two situations for sound dropping out when use them as a pair of true wireless earbuds.

1. Only sound from left earbud cuts in and out

2. Sound from both earbuds drop out

Please refer to the following troubleshooting:

Only sound from LEFT earbud cuts in and out - it means bad connection between the both earphones.

Sound from both earbuds drop out - Since the RIGHT earpiece is the MASTER, it means bad connection between the mobile device and the right earpiece.

  • Please try to clear pairing history and try again
  • Please make sure you put the smart phone at the RIGHT SIDE of your body for better connection with master piece.
  • Please stay away from any interfered environment, such as wifi router, other Bluetooth device and any other wireless devices.
