Review on 📢 TK Products VoiceBooster MR1505: Powerful 12w Voice Amplifier - Ideal for Teachers, Coaches, and Presentations! by Shirley Johnson

I wish this product was available when I teach six hours a day and strain my voice. Now I work as a tour guide and a voice amplifier helps a lot when working with large groups. I leave the battery charged between events but haven't used it for more than three consecutive hours. This should take much longer. My voice is not distorted even at maximum volume. My only criticism is the microphone. It must be positioned correctly in front of the mouth. Head movements during a call will cause the headset to move. Otherwise it's a good product at a good price.
