DO NOT charge the battery or turn off your headphones while downloading updates, transferring
data, or updating. Doing so may cause the headphones to become unusable.

other devices that use the 2.4 GHz band frequency radio waves.
Make sure both devices (Android/iOS device and the headphones) are fully charged.
