You might be familiar with Sonos’ high-quality music gear, which lets
you stream tunes anywhere in your home over its own Wi-Fi network. The
new S5 is a set of self-contained powered speakers that can expand an
existing system or serve as the starting point for a new one.
Intriguingly, the S5 lets you take a pass on Sonos’ effective (but
pricey!) $349 dedicated remote, offering a free iPhone app to control
all your Sonos gear.
