Echo Dot (3rd Gen) Charcoal | with Amazon Basics

Like previous Echo Dots, the speaker has a colored light ring around the edge and four buttons on top: volume buttons, a mic mute, and an action button. I like the Echo Dot's volume buttons better than the Home Mini's slightly mysterious touch controls, although you'll almost certainly be controlling the volume with your voice. The speaker is 3.9 inches in diameter by 1.7 inches high, and weighs 10.6 ounces. It's portable in the sense that it's easy to pick up and move from room to room, but it needs to be plugged in for power.
