Hi there @Aditya
Thanks for letting us know. Sorry for the inconvenience.
Could you please try charging your case with the supplied cable? If not, do you have a QI wireless charger to give it a go as well? It could be that your phone charger doesn’t meet the requirements to charge the ear (1).
Do the LED lights switch on when connected to your charger? You should have a red light constantly on.
Rest assured, we’ll get this sorted for you.
