The advanced technology Bionic Ear is a battery operated (one 9 volt) professional sound amplifier that allows you to zero in on sounds and whispers up to 100 yards away. This professionally-used unit comes complete with headphones, a 12 inch parabolic “BIONIC BOOSTER” dish and Omni-directional microphone to increase the power, clarity and directionality of the specific sound while eliminating a large proportion of surrounding background noises.
