UE Megaboom

Ultimate Ears’ Boom is amongst the overall best portable Bluetooth speakers you can buy, but if the compact device isn’t big or loud enough to fill your [evidently immense] room with music, the Megaboom should do the trick. This Bluetooth speaker blasts out 360 degree sound like its smaller sibling but boasts a longer, thicker form factor and bigger drivers, including dual 2″ drivers and two 4″ passive radiators, all in all translating into much more substantial sound. It can also Double Up with a second Boom or Megaboom to go full stereo, is IPX7 rated — i.e. fully waterproof to survive accidental trips to the bottom of your pool — and lasts for 20 hours on a single charge.
