The UE Boom 2, UE Megaboom and UE Roll Bluetooth speakers stand for musical enjoyment at any time. All of the speakers are waterproof and thus optimally suited for any kind of weather. Their plasma coating is conceived in such a way that the speakers can acquire a beautiful unique patina differing from user to user. Those who prefer a device without traces of usage can easily clean the speaker by rinsing it under a faucet. Each speaker also offers individual advantages, such as tap control on the UE Boom 2, full range sound with the UE Megaboom and the elastic strap of the UE Roll.
