Mine did that yesterday and I still haven't been able to get it paired again. It had been working fine the previous hunts. I'd turn on the detector, choose the wireless headphone icon, and it would pair right up. Yesterday, I did the same steps and it didn't pair......just went totally silent everywhere. The detector seemed to work....at least it gave a visual reading on the screen when I ran it over a target, but, no sound anywhere. I then restarted the detector and chose the external speaker, That worked no problem. Tried several more times to get the headphones paired again, but, no luck. Even went through the initial procedure to pair a set of headphones. No dice, I even unpaired and then tried to pair. Still no good. Headphones show a full charge just like all the other components. Any ideas before I throw this thing in the trash?
