Does BeHear use the cell phone’s microphone? If so, what is the lag time before the sound reaches your ears?
All models of the BeHear personalized hearing amplifier have their own microphones, four in total. Two are located in the ear buds, and two in the control boxes on the cables. BeHear doesn’t use the cell phone as a microphone. The lag/processing time is undiscernible – about 20 milliseconds.
