Sonos Era 100 review: Affordable multi-room audio that actually sounds good

Of the two speakers Sonos announced earlier this month, the Era 100 is much easier to sum up: it's a replacement for the Sonos One, which was first introduced in 2017. Unlike the Era 300, there's no need to ponder the value of spatial audio; the Era 100 is a relatively straightforward mono speaker, just like the One and the Play:1 before it. Don't let that simple description deceive you, though – the $250 Era 100 is a complete redesign, inside and out, and the end result is a worthy upgrade and a very versatile speaker. At first glance, the Era 100 looks quite similar to the One, but upon further examination you'll notice a number of small but meaningful changes. That starts with the vertically-oriented Sonos logo that you'll find on most of their other speakers like the Roam and, naturally, the Era 300.
