Zoweetek mini amplifier has quality sound

This was my first product to review on Rank Bosster. Very grateful to have the opportunity to test this amplifier. It worked very well as I tested it on my kids. When they are upstairs with the door closed and the fan on, they can never hear me. I even try to call there cell phones at time but either they are on "Do not disturb' or they don't pick up. Well, they heard me loud and clear when I called them with this amplifier. The sound is actually very crisp& clear with no static or echo and loud enough for them to hear upstairs with all of the things I described going on.
