What binoculars did for vision, this product does for listening. Produces an adjustable 50 decibel gain on sounds picked up from its multi-element high sensitivity microphone.

With only a single AAA battery, this lightweight device produces nice results. Use to amplify bird sounds (can be clipped to binoculars), frogs at night, or use during a lecture to get all the details. Comes with high quality stereo headphones.
