I have tried 5 different blue tooth speakers since getting my Nexus.
Ihome, Soundfreaq, JBL Flips and Jambox. Each one just wasn't very good. The last one I tried being the Big Jambox. It is comparable to the Bose Sound link. This thing rocks. It isn't as portable as the others I have had but still has a 10 plus hour battery life. I can bring it room to room with no problem. I love bringing my music with me in the morning when I shower. Helps me wake up! Great bass and volume.
Movies are incredible. It has a live sound option that really does an amazing job at spacializing. It gives the illusion of speakers around the room. It is kind of pricey retail over 250 but I was lucky enough to find one on CL for half that. Now I just need to sell my mini Jambox!
