I just bought my UE hyperboom speaker 3 days ago and when I came back home then I charged it, and after charging when I tried to turn on the UE hyperboom speaker but it keeps turning off.. and I was thinking to myself,what's happening with this UE hyperboom speaker because it is brand new., but then I put back on charge and when I turn it on then it works, and now I tried to turn on again it keeps turning off..why is that??
