Amazon's Echo Dot drops to just 28

Not all connected speakers have a voice assistant built in. The Sonos One SL, for instance, doesn't have a microphone. So, if you want to use your voice to control such devices, you may need to pick up a secondary smart speaker, such as Amazon's Echo Dot. As luck would have it, that little Alexa-enabled device is on sale for 28. The Echo Dot is a solid smart speaker, especially at this price.
