does this make anything from your phone louder?
hubby uses his phone GPS when he travels and is hard hearing in 1 ear, would this make the voice from the GPS louder? Also does it make any application that has sound louder?
There is a volume control and I am hard of hearing on one ear also. I don't have any trouble hearing without it being set on the highest volume. I've never tried anything other than making a cell phone call, but seems to me it would make the GPS voice louder also.
