I was trying to use my headset the other night and it turned on but I couldn't talk nor hear through it, it keep making a really quite beeping noise to when i had it in my ear. I tried deleting it and re-resgistering it but when I tried to turn it on it just kept going into discovery mode. Its not flat either. I tried it with both methods of pairing, discovery mode and using a USB cable but nothing. Someone please help, I don't want to have to buy a new one but I'm out of ideas.
