    Perfect BT speaker for teens. This is the 3rd or 4th one we’ve purchased. Makes a great gift. A pair of them will work together as left and right stereo channels. Sounds great for its size.

    I was honestly underwhelmed about the sound quality of the wonderboom 4. It was not even as good as a common amazon echo. There is no app support to eq the sound either, so you get what you get.
