Editor's Pick: You can safely take it to the poolside or have it float in the water—it's IP67 waterproof and floats, so playing music in the bathroom while you shower is totally worry-free. The sound spreads 360 degrees, so if you bring it to a backyard BBQ or hang out on the lawn, everyone sitting in a circle can hear it clearly. A single charge lasts about a day of regular listening, and the USB-C charging cable works with your phone too.
