In-Ear Amplifier

     I got this little amplifier made for kids on E-bay for $3 (it is called a "Spy Ear"). It is an amplifier with a built in microphone that will amplify sounds up to 50db. I use this with earphones to listen for faint sounds, or I attach it directly to a recording device to make it more sensitive. For $3 it's a great little gadget to play with.
