Summary: Bought it during Black Friday, so there should be no complaint for the 80 bucks spent. However there are reviews saying that it's a top class bluetooth speaker are really doubtful/irresponsible. It's in fact not as good as Bose Soundlink Mini, Klipsch KMC1... not even come close to them.
Summary: Great sound and very good price. Bought 2 of D5x speakers and one DSx subwoofer and made a 2.1 channel speaker system. Blutooth paring works great and the music comes out with much more wonderful sound.
