Why my h910n not playing any sound

So I had this Sony h910n for a couple of months and it was working perfectly until one day I turned it on and I couldn't hear any sound not even its own opening sound. Tried factory resetting it and looked through the internet but I couldn't fix it .

Any advice/solution will be much appreciated :))

Kacem Abdelbaki how old is it and have you replaced the battery yet? Have you tried to pair it again? What happened when you did the factory reset?

First of all sorry for taking so long .

Well when the problem appeared it was just a couple of months old and no didn't try to replace the battery because the application shows that it's fine and no the factory reset did nothing . I'm just using it paired all the time now .
