Samsung is releasing three new 360-degree wireless speakers -- the R1, R3 and R5, which it showed off at IFA this year -- as a follow-up to its Portal-esque R7 device. They're not quite egg-shaped like their predecessor (and its own predecessors), but they feature the same "ring-radiator" technology that helps them fill a room with sound. Plus, they now have a physical user interface on the top panel that allows users to quickly play, pause, adjust the volume and switch music sources.
