Beats Solo 3 won’t stay connected to any devices

My Beats Solo 3 will not stay connected to any devices and do not show that they are charging. When I try resetting them they will show connected for a few seconds and then disconnect. When I plug them in to charge none of the lights are on except the power button. After I reset all of the lights are on. My firmware is 7.8.8. What else can I try. The trouble connecting has happened on two different iPhone 11s and an iPad.
