It is very small and inconspicuous, yet it can amplify sounds up to 40 or more decibels (that means you will be able to hear some things over 1000 times better!). It is a fun toy for kids, and a useful tool for adults!Just plug in the earphones and turn on the device, adjust the volume to your comfort level, and you are ready to go! You can wear it at your side and amplify all sounds around you, or you can aim the microphone at a source to amplify specific sounds! Batteries not included.
