Sonos Era 300 Review: Stunning Spatial, Superior Sound

No, of course you don't buy a speaker to look at it. But should your gaze fall upon your speaker while you're enjoying its sound, ideally the sight of it shouldn't make you wince. So it's just as well that Era 300, the latest Sonos wireless speaker and the company's first foray into spatial audio (except for its Dolby Atmos–enabled soundbars, of course), is such an impressive and accomplished performer--its physical appearance is easy to overlook. Unless you somehow find it in your field of vision unexpectedly, anyhow, in which case it never ceases to be startling. It's fair to say Sonos' ubiquity has, until now, been established as much on its utterly painless ownership experience as on the sound its products actually make.
