Yea that true but UE is more outdoors durable. Thouse JBL Xtreme and Big Blue party more inside house but for inside house you can get spearkers that you dont need to charge :D. Big Blue party sound nice but battery holds only ~4.5h sad :(
I´m not going to vote, because I´m not going to buy, but if you want to add more, I recommend you JAM STREET bluetooth speaker, it is cheap and durable.
I'd love to see the UE Boom on MD. A friend of mine got one of these and I was crazy surprised how good it sounded. The idea that I could bring a second one over to her place and we could connect them makes me want one of these even more.
