It's been nearly two years since Sonos unveiled its PLAY:1 streaming speakers, though there have definitely been some special editions of it since then. Today, Sonos is showing that it hasn't forgotten about it nor has it abandoned the faithful fans who purchased one. The latest 5.4 update makes the speakers still relevant by improving its output quality. Of course, that's not the only thing that Sonos is pulling in. It is also emphasizing its commitment to rid your home theater system of restricting and tangling cables.
