Welcome to the community, thank you for your message. I am very sorry to hear that you are experiencing this issue with your SoundLink Color speaker. We would love to do what we can to get this resolved for you.
Could you inform me with that your systems LED indicators state when you attempt to charge your speaker? Have you attempted using different charger outlets and cables.
I would firstly check for any available firmware updates for your headphones. This can be done via a computer using a USB and visiting our firmware update website which can be found in THIS LINK.
