I purchased my studio 3 wireless headphones not even a year ago, about 7 months. They were working fine, even this morning. However, I came home and plugged them to charge as the LED indicators were off. Plugging the headphones in usually lights them up and I can power on the headphones. However, when I plug them in, the LED indicators are very dim and steady. Then, they fade out to nothing. I can't even power them on. I can't even reset them. Nothing happens. Very disappointed.
