I use stereo headphones and a dumb box with a 3 position, 2 pole rotary
switch. Left position = left radio/both ears, center position = left
radio/left ear and right radio/right ear, right position = right radio/both
ears. Have heard others like Jay who use a potentiometer to mix audio in
both ears and find it helps. I've never tried it so can't comment on it's
effectiveness. Others ?
