I just bought a new Plantronics M70 bluetooth headset. It says that when you turn it on something is supposed to happen, but it didn't. I tried plugging it up to charge and nothing happens. I haven't seen the indicator light come on at all, with the power switch turned on or off. I don't know if I'm doing something wrong if this thing just doesn't work?
