Sonos One SL
The Sonos Era 100 and Sonos One SL are compact wireless speakers designed for home audio, but they target slightly different users. The Era 100 is the newer generation model, featuring Bluetooth 5.3, auxiliary input support, dual tweeters for wider stereo separation, and upgraded processing for deeper bass performance. In contrast, the Sonos One SL focuses on simple Wi-Fi streaming and AirPlay 2 integration in a smaller and lighter design. If connectivity, flexibility, and future-proof features matter, the Era 100 has a clear advantage, while the One SL remains a capable option for users already invested in the Sonos ecosystem.
Verdict
The Sonos Era 100 is the stronger overall speaker thanks to its enhanced acoustic design, Bluetooth connectivity, auxiliary input support, and improved stereo performance. It is the better choice for most buyers looking for versatility and richer sound. The Sonos One SL is still a solid option for users who primarily stream over Wi-Fi and want a more affordable entry into the Sonos ecosystem, but it lacks the modern connectivity features found on the Era 100.
