Sonos Era 100 SL Review: Big Sonos Sound Without the Microphones
The Sonos Era 100 SL is the Era 100 minus its microphones: the same compact speaker, the same room-filling stereo sound for its size, and the same Sonos app and whole-home system, with no built-in voice assistant. Owners single out the sound quality, the quick app setup and how cleanly it pairs into stereo or surround setups, while the trade-offs are the closed Sonos ecosystem and the optional adapters that line-in and Ethernet require. For Sonos owners and privacy-minded buyers who already have a voice assistant elsewhere, it is a strong value.

Who is the Sonos Era 100 SL for?
The Era 100 SL is the microphone-free version of the Era 100, made for people who want Sonos sound without an always-listening mic in the room. It is the same compact speaker as the Era 100, so it suits small and medium rooms, kitchens, desks and covered outdoor spots. It is also the natural pick for building out an existing Sonos system: pair two for true stereo, add them as rear surrounds behind a Sonos soundbar, or spread them from room to room for whole-home audio. Buyers who already control their home through a phone, a soundbar or another assistant get the sound and the multi-room features without paying for a voice assistant they will not use.
What owners love
Sound is the headline. Owners repeatedly call it excellent for its size, with strong bass, clear vocals and enough output to fill a room, and several rate it above other compact speakers they have tried. Setup is a close second: the Sonos app walks through it in minutes, the speaker joins an existing system cleanly and stays in sync with the other Sonos speakers. Many buyers use them as surround rears or as a stereo pair and describe the result as a real step up. The microphone-free design is itself a selling point for people who run Apple Home or simply do not want microphones at home, and reviewers also like the fast Bluetooth pairing and the well-behaved AirPlay 2 streaming from Apple devices.
What to know before you buy
The Era 100 SL lives inside the Sonos ecosystem. Setup and control run through the Sonos app, and at least one owner found that unrelated music apps would not see the speaker, so treat it as a Sonos system device rather than an open Bluetooth speaker. There is no built-in voice assistant: the SL drops the microphones that let the Era 100 answer Alexa or Sonos Voice Control on its own, though it still works with the major smart-home platforms when you drive it through them. Two connections need accessories sold separately, the Sonos Line-In Adapter for a turntable or other analog source and the Sonos Combo Adapter for wired Ethernet. A handful of owners report the app losing a speaker or a unit that stopped appearing after setup, and the warranty runs one year.
Is the Sonos Era 100 SL worth it?
For anyone already inside the Sonos system, the Era 100 SL is close to a no-brainer: it is the cheaper route to the Era 100 sound and multi-room features if you do not need an on-board assistant, and it is an easy way to add stereo or surround channels. For newcomers it is an appealing entry point into Sonos sound quality, provided you accept the app-driven ecosystem and the optional adapters. If you want a speaker that answers you by voice, or you want to keep using an unrelated music app for playback, weigh the standard Era 100 or another brand first.
Frequently asked questions
Does the Sonos Era 100 SL have a microphone?
No. The SL is the microphone-free version of the Era 100, so there is no microphone to mute and no built-in voice assistant. The acoustics and the rest of the feature set match the Era 100.
Does it work with Alexa, Google Home, Apple Home and Home Assistant?
Yes. It integrates with Apple Home over AirPlay 2, plus Google Home, Alexa, Samsung SmartThings and Home Assistant, so you can control playback and grouping through those platforms. That control comes from the platform, not from a microphone on the speaker.
Can I use two Era 100 SL speakers for stereo or surround sound?
Yes. Two units pair into a true stereo pair, and they can serve as rear surrounds behind a Sonos soundbar. Owners commonly buy a pair for exactly this.
Does it have Bluetooth and a line-in?
It has Bluetooth 5.3 for direct streaming and AirPlay 2 for Apple devices, on top of dual-band Wi-Fi. A 3.5 mm line-in for a turntable or other analog source needs the Sonos Line-In Adapter, and wired Ethernet needs the Sonos Combo Adapter, both sold separately.
What colors does the Sonos Era 100 SL come in?
Two: Black and White.
Do I need the Sonos app to use it?
Yes. Setup, grouping and most day-to-day control run through the Sonos app, and the system is built around it, so the speaker suits people who are happy to stay in the Sonos ecosystem.
