Who Should Buy This
The Sonos One SL (2019) is perfect for people who want great sound in a small space. It works well for those who want to add music to any room without extra wires. If you already have other Sonos speakers, this is a great way to expand your system. It is also good for those who do not need voice control but want clear, rich audio.
This speaker is not the best choice for people who want built-in voice assistants like Alexa or Google Assistant. Also, if you need a very loud speaker for big rooms or outdoor use, you might want to look for something bigger. Finally, if your budget is very tight, the price might be a bit high for just one speaker.
