Just like earlier iterations, the Echo Dot is a small speaker with the Alexa virtual assistant, so you can use voice commands to play music, control smart home devices, and perform other tasks. The new Echo Dot has a “redesigned audio architecture,” with higher quality speakers that aim to deliver clear vocals and twice the bass of the previous model. It’s still shaped like a sphere — if you were hoping for a return to the more compact disc shape of the original Echo Dots, you’ll have to look elsewhere.
