Powerhouse Sound

I have had wonderboom devices since they first started making them. If you connect two speakers together they make an amazing sound pair in any room. Only have one, no problem! They are a powerhouse of great sound!

Great Buy

There was no product photo when I purchased so I added one. These speakers work really great and you can connect them to each other. It's a great buy!

Upgrade from previous version

This is a good product. Upgraded from a previous version that I already loved and this one has a superior sound and battery life!
