Sonos Play:3 (Overall Winner)
Battery life: Plug-in only
Not only a wireless speaker, Sonos is a music-management and distribution system that includes hardware and software. The lunchbox-size Play:3 adjusts its output depending on whether it’s flat or sideways. All Sonos products work on a proprietary wireless network. The instructions are clearly written and not altogether hard, but it does require more effort than a Bluetooth setup.
