I cant hear anything out of my headset

My H700 worked perfectly, until I tried to turn up the volumn. Since then I have no sounds at all, except the beeps on the ear set. Everything is still working on the phone. Example, when I tap the ear piece phone button, you hear the beep, after which it use to say, "say a command". It shows that on the phone, but that is it. If it connects to the a phone, and you answer that phone you can hear nothing. Anyone know what's going on? I am assuming the mute is still on, but can not get it off?
