My suggestion you try to drain the battery. Simply put led light or anything to usb. And after that charge it using low amp (0.5A) charger or connect it to computer and USB port.
Left it overnight and try to turn it on. PS. After the batter drain. Charging led won’t blink even you plug in the charger and its normal behavior
I asked for a return and exchange with other model. You should do it too. Also dont insert anything inside the microphone thinking it is a reset button.
If I connect another device it charges the connected device and i also hear windows sounds.
