These days it's hard to break new ground with wireless Bluetooth speakers, but UE is doing its best with the Roll, a waterproof Bluetooth speaker that looks like a saucer-shaped UFO, is fully waterproof, and comes in six different color options at launch. It costs $100 in the US, £80 in the UK and AU$150 in Australia.
You can get cheaper Bluetooth speakers that do the job, but the small yet versatile UE Roll has more to distinguish itself for the price -- both in terms of design and performance.
The UE Roll is a compact, waterproof Bluetooth speaker with a unique design, very good sound for its size, and decent battery life; It has an integrated bungee cord and an inflatable life preserver (included if the speaker is purchased through UE's website) that allows it to float in water.
It has no speakerphone capabilities.
