Welcome to the Apple Support Communities!
It sounds like you are not able to turn your Beats Flex earphones off, and we'd like to help.
Try charging your earphones for at least 30 minutes before troubleshooting.
Set up and use your Beats Flex earphones
"The power button is on the right control module. Press and hold the button for 1 second to turn your earphones on or off."
When you tried to reset the earphones, did you wait until the LED indicator light flashed before releasing the buttons?
If not, try resetting the earphones again.
