Consider the Mic Switch When Choosing a Smart Speaker

Why the microphone switch matters
The Era 300 ships with a built‑in microphone array and a hardware toggle on the rear panel that physically cuts power to the mics. In the Sonos app you also enable or disable voice assistants (Alexa, Google) and set hot‑word detection. This two‑step control—hardware switch plus software setting—gives you a clear privacy breakpoint.
The Era 100 has no microphone hardware at all. All voice‑assistant features are unavailable, and there is nothing to toggle. It functions purely as a networked speaker.
Conditional buying judgement
- Choose the Era 300 if your household regularly uses voice commands (e.g., asking for music, news, or smart‑home control) and you are comfortable keeping the mic enabled most of the time, relying on the physical switch for a quick privacy kill‑switch when needed.
- Choose the Era 100 if you prefer a speaker that never listens, or if voice control is an occasional, separate device (like a dedicated Echo or Google Nest) that you can place away from the main listening area.
Practical alternative
If you want voice control but are uneasy about a permanent mic on the speaker, keep the Era 100 for music and add a stand‑alone voice assistant on a nightstand or kitchen counter. That device can be turned off or moved when privacy is a priority, while the speaker remains microphone‑free.
In short, match the hardware presence of a mic (Era 300) or its absence (Era 100) to how often you need voice interaction versus how strongly you value privacy.
