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!

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!

Small but awesome

I love these speakers. The sound quality is excellent and the battery life is much better then the previous edition I had. Love the big sound from syncing two together.
