First looks

Sonos Era 100 review

Sonos uses the term ‘hourglass’ to describe the form and overall exterior of the Era 100. Maybe the manufacturer wants to throw us off because the design team’s take on the hourglass concept is not what you’d expect. Their take translates to a black or white cylinder with curved surfaces at the top and bottom of the speaker.

Cylindrical smart speakers like the Sonos Era 100 have an aesthetic that works with all kinds of décor.  This six-inch elliptical cylinder is all curves and neutral colors that blend with whatever space the speaker occupies. A solid exterior with a polycarbonate grill covers the bulk of the speaker’s curved surface. The only break to the mesh texture of the cylinder is the smooth plastic panels at the top, bottom, and back of the speaker.

Sonos Era 100 review: Build

The back panel runs along the height of the Era 100; from top to bottom. At the very top of the panel is a Bluetooth button that you use to enable and disable Bluetooth functionality.

You also get a physical ON/OFF switch that lets you activate and deactivate the microphone. This is an important feature for people who are strict about privacy in their spaces. Next to the microphone button is a USB-C port that you can use to connect all manner of devices. All you need is one or more adapters with a USB-C connector on one end.

Connectivity and controls

The USB-C connector and the power jack are the only physical ports on the Sonos Era 100. All other connections will be wireless, via an internal adapter that provides Bluetooth  5 and WiFi 6E connectivity.

You’ll find a few capacitive touch controls on the top surface of the Sonos Era. For starters, you get a backlit groove that lets you control the volume by swiping a finger along its length. You also get a pair of navigation buttons that you can use to scroll through playlists. A play/pause button completes the set of physical controls on the speaker.

Sonos Era 100 review: Hardware configuration

Sonos designed the Era 100 to disperse sound from the front and sides of its curved exterior. The speaker uses two tweeters and a 4.5-inch oval woofer to execute a three-channel, 270-degree soundstage. Each tweeter forms a side channel that covers treble and upper mid-range frequencies. The forward-firing woofer simulates a center channel while doing a good job of rendering bass and mid-range frequencies.

The drivers are powered by an array of amplifiers that get their instructions from circuitry at the back of the speaker. Lastly, a set of waveguides shape, steer, and direct sound output from the drivers. creating the ultra-wide soundstage of the Era 100.

What you get from this configuration is a stereo soundstage with distinct audio elements that seem to come from exact, pinpoint locations.

Sound profile

The Sonos Era 100 renders the type of sound that delivers definition, detail, and cohesion; all at the same time. Different sound elements seem to come from different locations in the wide soundstage. Each strain of sound stands out in its own right, without overpowering sound elements with similar frequencies.

Only the deepest bass elements threaten to overpower the high-treble sound. So it’s a good thing that the Sonos companion app comes with an equalizer module that allows you to adjust the bass levels of the Era 100.
