“Modal Over-the-Ear Headset Won't Turn Off < MD-HPBT01 > I experienced this issue, and I found the answer in the manual at http://goo.gl/VOFVcD To reset the headset, press the Play, Talk, and Volume Up (+) buttons simultaneously. These are the buttons with the picture of the phone, the >||, and the + buttons. It will power off. This seems to occur every couple months randomly. I love the headset, so I am thrilled now that I know how to resolve this issue easily. It will be necessary to pair it with devices again, but no big deal.”
