Best Wireless Speaker: UE Boom 2

Last year, our favorite Bluetooth speaker—really, one of our top tech products overall—was the UE Boom 2. It wins again this year. The compact $200 speaker sounds amazing and goes more than 15 hours on a charge. It stands vertically, spreading stereo sound in a wide arc, and has a footprint about the size as your morning beer. Incredibly, it's fully waterproof, so you can take it to the beach and try to lose it in the ocean. And since the speaker is massively popular and all of your friends have one, you can take advantage of a new software update that lets you connect two, three, seven, twenty-eight speakers together to blanket the whole party in sound.
