I've been using these headphones for a while but a glitch keeps occurring. I plug my headphones in when I go to bed. The red light shows up like in the manual then turns off once charged. In the morning I unplug it and there is no response whatsoever. I have to wait for it to fix itself. Sometimes I have put it back to charge but no red light appears and then it fixes itself somehow. I'm using the right adapter and the charging time is 3 hours.
