Our top pick is a larger version of the UE Boom, which was our previous favorite. They share a similar sound: The UE Boom is fuller, clearer and more robust than most Bluetooth speakers can muster. The Boom doesn’t play as loudly as the Megaboom, though, and it’s not as waterproof. It will survive a splash, but not a full dunk in water. If you want something more affordable and/or more portable, the Boom ($180 on Amazon) is a great choice. The UE Boom has a big sound for its size, plus the same app-based features as the UE Megaboom, our top pick. It can be used vertically or horizontally and is available in 16 color combinations.
