t700 icon headsent ever up! :(

Hello I have a problem with my T700. As soon as I turn I see the icon of the headset alone although this is not connesso.Alcune times before it loads all the files you can hear the music but also of the headset icon appears and does not feel anything. I think it's a software problem as I reset it?
