This Mic-Less Sonos Speaker Is Now on Sale at Its Lowest Price Ever.
As the first Prime Day deals roll out (for more details, check out our Prime Day 2026 guide), the Sonos Era 100 SL on Amazon has dropped to $169 from its regular price of $189, which, according to price tracking sites , is its lowest price yet. Essentially, this is a microphone-less version of the standard Era 100. You lose support for Alexa and other voice assistant features, but everything else remains the same, including stereo sound, Bluetooth connectivity, room correction technology, and access to the broader Sonos ecosystem.
Unlike the Sonos One SL , which is a mono speaker, the Era 100 (and its SL counterpart) uses a stereo speaker configuration, which delivers a noticeably wider soundstage and better instrument separation. In practice, this means instruments and vocals sound more distinct, rather than merging in the center of the room, which is crucial for high-quality recordings. There are also room correction tools that adjust the sound output based on your listening environment, as well as manual bass and treble adjustments for further customization. Built-in Bluetooth support, which hasn’t always been a feature of Sonos products, makes it easy to connect guests without having to connect to your home network.
Another compelling reason to consider this model is its ecosystem: the Era 100 SL works with the Sonos app and can be combined with other compatible Sonos speakers to create a whole-home audio system. You can start with a single speaker and expand the system over time without replacing anything. It doesn’t support Dolby Atmos music like the more expensive Era 300 , and it lacks the power to fill very large rooms with sound without issue. The sound can also lose some clarity at maximum volume. However, if you’re looking for a compact wireless speaker that prioritizes sound quality over smart assistant features, the Era 100 SL offers much of what makes Sonos popular at its lowest price to date.
