No i literaly meen like a fuzz sound that changes its pitch like the inner working of a computer almost kind of like an old land line connection if u picked up the phone and listened, obviously not as loud. I hear it in calls as well as not. Sometimes i dont hear it at all but usually in a call i hear it. Again ive only had the device for 5 days. I have no idea what it could be. I just picke dit up now and listened without fone call didnt hear anything at first but than heard a patern of fuzz noises like duhhh duhh da duhh duhh almost morse code like
