Sonos Era 100 Wireless Smart Speaker – Comprehensive Review

Today we’re taking an in-depth look at the Sonos Era 100, the latest addition to Sonos’ lineup of premium wireless speakers.

This compact yet powerful smart speaker promises impressive sound quality, seamless multi-room audio, and smart home integration. But does it live up to the hype? We’ll examine every aspect of this speaker to help you decide if it’s worth your investment.

Design & Build Quality.

The Era 100 maintains Sonos’ signature minimalist aesthetic with a sleek, cylindrical design that fits beautifully in any room. Measuring just 6.3 inches tall and 4.7 inches wide, it’s compact enough for bookshelves, countertops, or nightstands while still delivering room-filling sound.

The matte plastic exterior feels premium and durable, with a subtle texture that resists fingerprints. Physical controls are limited to a touch-sensitive top panel for play/pause, volume, and microphone mute – a clean look that prioritizes app control. The speaker comes in black or white options to match any decor.

Sound Performance.

Where the Era 100 truly shines is in its audio performance. Sonos has made significant upgrades from previous models:

Dual-tweeter array creates impressive stereo separation from a single speaker.

• 25% larger midwoofer delivers deeper, punchier bass.
• 47% faster processor enables more advanced sound processing.

In testing, the Era 100 produces remarkably clear highs, detailed mids, and surprisingly robust bass for its size. The soundstage is wide and immersive, especially when placed properly in a room. Compared to the Sonos One it replaces, the Era 100 offers noticeably better instrument separation and vocal clarity.

At around 40% volume, the speaker hits its sweet spot – delivering rich, balanced sound. While it can get quite loud without distortion, very low volumes (below 20%) do sacrifice some clarity as noted in the negative review. This is common among most speakers in this class.

Smart Features & Connectivity.

The Era 100 is packed with modern connectivity options:

• WiFi streaming for high-quality audio from all major services.
• Bluetooth 5.0 for direct device playback.
• Line-in capability (with optional adapter) for turntables or other audio sources.
• Alexa voice control built-in (but no Google Assistant).
• AirPlay 2 support for Apple users.

The WiFi streaming is particularly impressive, supporting high-resolution audio from services like Tidal, Amazon Music HD, and Apple Music. Bluetooth is convenient but limited to standard quality – WiFi is where this speaker truly excels.

One notable limitation is that Android users miss out on some features. The advanced Trueplay room correction (which automatically optimizes sound for your space) requires an iOS device. Android users only get basic microphone-based calibration.

Setup & App Experience.

Setting up the Era 100 is refreshingly simple: Plug in power, Open Sonos app, and follow on-screen instructions.

The entire process takes just a few minutes. The Sonos app has received criticism for being buggy, but in our testing the latest version worked smoothly for basic playback and grouping functions.

The app provides: Bass/treble adjustment, Loudness compensation, Speaker grouping, and controls.

Music service integration.

While the EQ options aren’t as comprehensive as some audiophiles might want (just bass and treble sliders), the default tuning is excellent for most listeners.
Multi-Room & Expandability

One of Sonos’ biggest strengths is its multi-room capabilities. The Era 100 can be grouped with:

• Other Era 100 speakers.
• Any Sonos speakers (including soundbars)

Sonos Sub Mini for enhanced bass.

As mentioned in the positive review, you can easily control which speakers are active – perfect for moving between rooms. The ability to pair with a Sub Mini (though only one per system) significantly enhances the low-end performance.
