The strangely named APA-WBA-200 is the perfect answer for people that have voice problems or simply want their audio message to reach a bigger public audience. It is a little device that can increase the volume of your voice, just attach it to your waist and control the volume up or down as required. The microphone is an adjustable headset that looks like one of those old-school bluetooth devices, I’m almost sure a new (read more technical and easy to use) mic could be implemented.

The Waistband Speech Amplifier works with 6AA batteries and the sound range is 50 meters.
