I am very sorry to hear this, I would like to do what I can to help!
Lets begin by rebooting your speaker, this will restore your Micro to its out of box state.
Power on your product
Press and hold the Power button for about 10 seconds until the Bluetooth® light blinks blue and a voice prompt instructs you to select a language.
Following this, check for any available firmware updates for your speaker. This can be done via a computer using a USB and visiting our firmware update website btu.bose.com, which will provide you with full instructions.
