I recently received a Jambra bluetooth ear piece for Christmas. I don't use it often except for when I'm in the car, however, each time I use it my ear and the area around it feels weird. My ear even rings a little. I'd like to use this thing but its very uncomfortable. Everything I've read about radiation etc., says the earpieces are safe and they actually emit less radiation than cellphones themselves. Does anyone have an idea why I might be experiencing these strange sensations?
