Using the LD Systems ANNY 10 BPH2 is a breeze. First, charge the battery fully. You can use the USB - C port to charge your mobile device too. Then, connect your microphones or music sources to the 6 - channel mixer. You can play music wirelessly via Bluetooth 5.0. If you want a more powerful sound, use the True Wireless Stereo (TWS) feature to link two ANNY 10 speakers. Adjust the sound using the 3 - band EQ according to your preference. When it comes to maintenance, keep the speaker clean by wiping it with a dry cloth. Avoid exposing it to extreme temperatures and moisture. When not in use, store it in a cool and dry place. And remember, the battery life is up to 25 hours in ECO mode and 5 hours at max volume, so manage your usage accordingly.
