Beats will not turn on. Help pls.

I recently bought a pair of Beatsx earphones. I have charged them, updated software, tried to find if there are any loose cables, attempted a reset on them and still they will not turn on. I know they work because when they are attached to the lightning cable the LED’s light up. It’s when i take it off charge when the problems start. They will not turn on. I hold down the volume down and power button for 10 seconds and it doesnt change anything. Just confused on what i can do.
