Mobile music enjoyment means earphones to a lot of people. But when meeting with friends outside, sharing of music is at the top of the list. This is child’s play with the UE Boom from Ultimate Ears. The source remembers up to eight devices. If a stronger volume is needed, two devices can be used in parallel. The distance between sender and receiver can be up to 15 meters. The Lithium-Ion battery runs up to 15 hours and is re-charged via micro USB. But the absolute highlight is the omnidirectional sound radiation. This eliminates the adjustment to the listeners. Just put the UE Boom into the center, switch it on and fun starts immediately.
