Beats Studio Wireless headphones not powering on

My headphones stopped working two days ago and I cannot get them to turn on now. I plug them into the charger and the charge light turns on red. After about a minute the light turns green. However, I can't get them to turn on, reset or flash any function lights while unplugged or plugged in. I have tried 10 second and 2 minute reset durations holding the power button, power and volume button, and power and mute button. I am still not getting any response from them. They still work when the audio cord is connected though. What is up with these headphones??
