Amazon Prime Big Deal Days means sweet sales on some of our favorite gear, and as perhaps the best smart speaker we've ever tested, the Sonos Era 100 certainly qualifies. This is the lowest price we've ever seen for Sonos' entry-level speaker, so if you've been looking to grab one or two of these stylish columns to fill your home's halls with sound, now's the time to strike. Also, be sure and check out our main Absolute Best Prime Day deals post and our Amazon Prime Day live blog for tons of deals across our favorite tested products. The Era 100 has it all: tons of features, responsive microphones for voice commands, sleek style, and even the great Giancarlo Esposito (or his voice, at least). Best of all for my money is the Era 100's fantastic sound, offering smooth midrange frequencies, sparkling treble, and punchy bass that's much more robust than you'd expect for the size (and price). Of course, there is an elephant in the room. The Sonos app, once the pride of the Sonos empire, has had some major issues of late, including dropping speakers off user networks, among other quirks. That said, Sonos has admitted its failures and worked hard to address user issues, including appointing a new CEO who has spoken frankly on the matter. That work seems to have paid off, as the software and hardware seem to be much more stable for users in recent months. For my part, the Sonos Era 100 and its pricier sibling, the Era 300, have both been working great on my network for months, providing stalwart connection to go along with their excellent performance. I've even recently connected an older Sonos/Ikea Symfonisk Lamp on my network for our newborn baby's nursery, and all three speakers have been working well in concert. The setup lets me enjoy all the bounty Sonos has to offer, including features like multi-room connection, prompt voice response, access to nearly any and every music streaming service, and extras like Bluetooth, Spotify Connect, and Apple AirPlay. The Era 100 also provides smooth and meticulously designed touch controls on top of the speaker, and even a line-in input. It all adds up to a slick and seamless smart speaker experience. Looking for bigger and bolder sound, including Dolby Atmos multi-directional speakers for 3D audio? Check out the Sonos Era 300, which is anoher one of our favorite smart speakers on a great sale right now for $379. Either way you go, you'll save big on Sonos' best.
