Smart speakers have become a must-have for most homes by offering an impressive suite of features that allow users to perform a variety of tasks through voice commands. While Amazons Echo series is arguably one of the best range of smart speakers, anyone looking for an affordable alternative can't go wrong with the Sonos Era 100. Usually sold for $249, Amazon's big Spring Sale has seen the Sonos speaker get discounted by 20%. Now, the speaker is available for $198, allowing new buyers to save $51.
