The regular Amazon Echo and Echo Dot product lines have been gotten more similar with each generation, and the newest Echo Dot is pretty hard to tell apart from the Amazon Echo (4th Gen). In fact, there’s almost no difference between these two products. The software side is identical, and there’s really only one meaningful difference to the hardware—the Echo Dot (5th Gen) lacks an aux input port. It is cheaper though, so if having a wired input method isn’t important to you, it may still be worth buying.
