We moved these units from phone to phone. I have it plugged into the new phone and if you are looking at the unit, the red light on the left just blink and the blue light that is on top is not on at all. I let them charge all day yesterday and today thinking it might be the battery. Can someone please help? I have to of these and they are doing the same thing.
