Auto power off

port (7) and the other USB end to any device with a USB charging port (PC, USB wall charger, car charger, etc.). The
charging time is approximately 2 hours.
Note:
To optimise battery life, do not store or leave the device completely discharged for a long time.
Caution: Do not charge your headphones with fast charging adapters or dedicated laptop charging adapters, Because
their output voltage exceeds 5V and the device may become unusable.

playback from your music player and not from the headphones.

for FM radio stations. The process may take a few minutes. Once the search has been completed, press and hold

storage card. If you connect the same removable storage unit once again, playback will resume from the last track you
listened to.
Press and hold Volume + / Next (1) or Volume - / Back (3) to switch to the next or previous track.

stops and the ringing tone sounds instead. You can also press and hold the very same button for 2 seconds to reject a
call.

The built-in microphone is designed to answer conventional phone calls from the smartphone. If you intend to connect
these headphones to your Windows PC or MAC and use them for home office purposes such as video calls (Teams,
Skype, Zoom, etc.), we recommend purchasing this add-on specifically designed for optimal performance:
