I think I was around 11 years old when my parents gave me an extremely fun device. The best description I could give of it was that it was a very small directional microphone. You would point it in the direction of what you wanted to hear, and the sound would be amplified. It worked really well - like, if people were whispering all the way across the yard, you could point it at them and understand what they were saying. It had a jack that a pair of headphones plugged right into; the microphone itself was small enough to be concealed in the hand.
What was this exactly? Browsing on eBay there are a lot of directional microphones but most of them are much bigger and fancier than this thing that I remember. Was there ever a small, children’s version of it made - sometime around 1997?
