I have a BlueAnt bluetooth headset which my Droid 4G can't seem to pick up. I repeat the steps over and over. Meanwhile, my phone can detect my computer. The headset is a couple of years old. I also have a Plantronics headset that is about one year old, and my phone did pair with it once but then lost the settings and refuses to pair with it again - can't detect it. Help! I don't want to have to buy another headset!
