Known for putting huge sound in a small package, Ultimate Ears releases its flagship wireless speaker, the UE Megaboom ($299). The Megaboom is their biggest speaker in the lineup with the same 360-degree sound as the original UE Boom, but now even more powerful and as rugged as ever. 

Just like the previous model, the Megaboom is waterproof, IPX7-rated to be exact, shock-resistant, a Bluetooth range of 100 feet, 20 hours of battery life, and can reach sound levels of up to 90dBA. You can even pair it with another UE Megaboom or a UE Boom for even bigger sound.
