Portable Bluetooth speakers still rock, but they definitely aren't in vogue like they were a few years ago. That doesn't mean they're stepping aside, though. As fun as it is to ask a smart speaker to play your favorite track, offbeat band names and track titles can still trip them up. They also rely on home Wi-Fi, and often lack batteries or features like waterproofing. For the past six months, I've tested about two dozen different Bluetooth-capable speakers, and researched dozens more online—these are still some of the best devices I've had the pleasure of hearing.
